This will let help us verify that we got the right thing when we pull
it out of of Doxygen XML for the official HTML documentation.

Fix @file in many places. Also fix up the descriptions where it's
appropriate. This standardizes the @file formatting across the library
to explicitly include any parent directories up to the repository
root.
Besides being nice, this will hopefully let us manage Doxygen's XML
output so as to make extracting series-specific pieces via Breathe in
the leaflabs-docs repo possible.

Change the values of the STM32_F1_LINE_xxx macros to match the part
number better (so performance line, or F103s, now have
STM32_F1_LINE_PERFORMANCE==3, F100s have STM32_F1_LINE_VALUE==0,
etc.). This will hopefully make debugging or error checking easier for
someone at some point.

Breaking change set up: struct dma_handler_config is no longer part of
the public API in <libmaple/dma.h>. User code which was touching
these was always mistaken; it should be using dma_attach_interrupt()
or dma_detach_interrupt() instead.
Other than that, just move the nonportable bits in <libmaple/dma.h>
and libmaple/dma.c to the appropriate places under
libmaple/stm32f1/. (Ouch. This is almost everything.) Patch the
(new) STM32F1 <series/dma.h> here and there to make everything
compile; this is mostly limited to forward-declaring struct dma_dev
and providing a hack _dma_dev_regs() declaration so inline functions
in the series header can still access a device's registers.

Add STM32_HAVE_USB feature test macro requirement for
<series/stm32.h>. This will let us test if we've got a USB peripheral.
wirish/stm32f1/boards_setup.cpp is set up to use this when turning on
USB CDC ACM support at init() time.
Rework the STM32F1 <series/stm32.h> to make it easier to support the
various lines that subdivide that series. We don't really support
anything besides performance line yet, but there's been enough
enthusiasm for value and connectivity line support in the past that
these hooks seem worth adding. This means adding an STM32_F1_LINE
macro and STM32_F1_LINE_[PERFORMANCE,VALUE,ACCESS,CONNECTIVITY] macros
for values that STM32_F1_LINE can take, and generalizing the rest of
the file to begin taking this into account. Some TODOs remain, but
filling these in is the responsibility of future libmaple porting
efforts.
One pleasant consequence of the F1 stm32.h rework is that the build
system no longer has to tell us what density of F103 we're building
for, so remove that from the relevant support/make/board-includes/
files.
Add some tweaks to <libmaple/stm32.h> and the STM32F2 stm32.h header
to make sure this went through properly, and continues to go through
properly in the future.

Put the section defining MCU-specific values before the other
sections. Surround the density-specific defines with #ifndef/#endif
pairs. This allows any of the settings in the STM32F1 stm32.h to be
overridden on a per-MCU basis. That's hopefully useful to e.g. people
porting libmaple to STM32F100 MCUs, which have slower clocks.

Standard family support refactoring: add STM32F1 series spi.h, spi.c,
and move anything that won't port to STM32F2 there.
As part of a general effort to be cleaner, remove the dependency on
libmaple/util.h from libmaple/spi.h by not using BIT(). Also forward
declare struct gpio_dev for spi_gpio_cfg() to remove that include.

This applies to XL-density STM32F1 devices.
In stm32f1/timer.c, add timer_dev's for the new timers, using the
timer_private API. These definitions are conditionally compiled based
on the target density to avoid wasting space on smaller MCUs. Also add
calls to the appropriate timer_private.h dispatch routines within the
IRQ handlers for these timers. We need to change the IRQ handler names
to reflect this eventually, but put that off for now, as it could
break backwards compatibility in some exotic situations where the user
refers to the libmaple IRQ handlers directly.
In stm32f1/timer.h, add register map base pointers and device
declarations for the new timers. timer_dev* declarations are compiled
in only when the target MCU supports them, in keeping with the above
stm32f1/timer.c changes.
In libmaple/timer.c, update the (static) IRQ enable routines to
account for the additional timers. This adds some code that's
unnecessary on smaller STM32F1s, but it's minimal (40 extra bytes on
my machine), so portability and readability win out.
Size change, using GCC version "(Sourcery G++ Lite 2011.03-42) 4.5.2":

This is a backwards-compatible change, but it deprecates some existing
functionality.
XL density STM32F1 devices have additional timers 9 through 14. These
share NVIC lines with timers 1 and 8. This scheme is also used on
e.g. STM32F2, so the corresponding nvic_irq_num enumerators on that
series have names like "NVIC_TIMER1_BRK_TIMER9" instead of
"NVIC_TIMER1_BRK". For portability (and XL-density support), it makes
sense to add these enumerators to the F1 version of nvic_irq_num,
which we do here.
For backwards compatibility, we keep the old enumerators (like
NVIC_TIMER1_BRK) around as aliases to the new ones (like
NVIC_TIMER1_BRK_TIMER9). These old enumerators are now deprecated.
Also fix up the Doxygen @file header.

Fix copy-paste errors in, and add missing, register bit
definitions. For copy-paste errors that would result in source
incompatibilities with past releases, add some legacy defines.
Add series header and C file for STM32F1 which fills in the missing
API. Much of the F1 timer.c would be repeated on F2, so also add
timer_private.h to hold these.
Support for timers 9 through 14 is still missing.

Whether or not a given peripheral is present on an F1 series MCU
doesn't matter. It doesn't take up any extra space to include these
enumerators, and it's convenient to have them defined so portable
libmaple routines can safely refer to them. This can prevent the need
for special series-specific versions of some functions.

This function has been with us from the earliest days of libmaple.
It's showing its age, as the API it presents is tied to the
STM32F1. Deprecate it, and provide instructions for how to use newer,
more portable APIs. The new way is more verbose, but we can always add
a portable "just set up the PLL, dammit" convenience function later (a
nice candidate is to extract an interface from setup_clocks() in
boards.cpp).

Standard refactoring: add series headers for F1 and F2, along with
series adc.c files. There are some issues relating to adc_extsel_event
to hammer out later, but this will do for now.
We also add some new portability interfaces to libmaple/adc.h in order
for Wirish to use the same code to initialize the ADCs at init() time.
As usual, F1 is untested.

FIXME:
- Test F1 support
- Solve problem of duplicated bytes being TXed unless delay is
inserted after configuration but before first bytes are TXed.
Rip out nonportable bits from top-level interfaces. The USART register
maps are basically the same between F1 and F2, so leave these, but add
register bit definitions which had name changes to the libmaple header
to avoid needless repetition. There are also a few new bits in the F2
USART registers; add definitions for these in the F2 USART header. Add
Doxygen comments for all USART bit definitions.
Deprecate struct usart_dev's max_baud field. This is just bloat that
doesn't bring us much real benefit.
Add new series-specific USART files for F1 and F2:
- libmaple/stm32f[1,2]/usart.c
- libmaple/stm32f[1,2]/include/series/usart.h
These are standard series-specific files, providing register map base
pointers, defining devices, implementing nonportable routines, etc.
We need a portable way to configure the USART GPIOs. To this end, add
usart_async_gpio_cfg() to the top-level USART interface. This function
is implemented in new F1 and F2 USART backends to take the appropriate
action to configure the RX and TX pins for asynchronous full duplex
mode.
USART baud rate calculation is done differently on the different
series. Keep the usart_set_baud_rate() declaration in the top-level
USART header, but move the implementations into the series-specific
usart.c files.
In usart_set_baud_rate(), allow for deriving clock_speed automatically
by letting user tell us to figure out the peripheral clock speed by
mapping the device's rcc_clk_id onto an STM32_PCLK[1,2] value. This
preserves flexibility for users with non-default clock configurations,
but makes things easier on everyone else.
Add private USART files for portable private USART routines:
- libmaple/usart_private.h
- libmaple/usart_private.c

The new style for configuring the PLL is to initialize
a (series-specific) struct rcc_pll_cfg, and pass a pointer to it to
rcc_configure_pll(). After that's done, you can use
rcc_turn_on_clk(RCC_CLK_PLL) to turn on the main PLL, and busy-wait
until rcc_is_clk_ready(RCC_CLK_PLL) is true to make sure the new
configuration took effect.
- libmaple/rcc.h:
-- Add struct rcc_pll_cfg, which specifies a PLL configuration. This
specifies a PLL source and a void pointer to series-specific PLL
configuration data.
-- Add rcc_configure_pll(), which takes a pointer to struct
rcc_pll_cfg, and configures the main PLL. It's up to each series
to define this function.
- stm32f1/rcc.h: Add struct stm32f1_rcc_pll_data, to store F1-specific
PLL configuration state.
- stm32f1/rcc.c: Add an implementation for rcc_configure_pll().
- stm32f2/rcc.h: Add struct stm32f2_rcc_pll_data, to store F2-specific
PLL configuration data.
- stm32f2/rcc.c: Add an implementation for rcc_configure_pll().

Additions:
- rcc_switch_sysclk():
For changing the clock used as SYSCLK's source.
- enum rcc_clk:
One for each system and secondary clock source (e.g. HSE,
LSE). These are defined on a per-series basis in each of the
<series/rcc.h>.
- rcc_turn_on_clk(),
rcc_turn_off_clk(),
rcc_is_clk_ready():
For turning on system and secondary clock sources, and checking
whether or not they're ready. Uses enum rcc_clk.
Removals:
- rcc_clk_init(): There's no way to port this to F2. Move it to the F1
header. This also means we can remove the empty implementation and
enum rcc_pll_multiplier from the F2 RCC header, where it doesn't
make any sense.
Also fix up some includes, and rewrite rcc_clk_init() in terms of the
new clock source management functions.

Make a single function, flash_enable_features(), to control the access
characteristics of Flash memory (i.e. to write to the non-latency bits
of ACR).
In so doing, make everybody pretend to allow instruction and data
caching. On STM32F1, trying to turn these on simply has no
effect. This allows unconditionally trying to turn them on, which will
simplify users' lives.
This has the ancillary benefit of making the stm32f2- and
stm32f1-specific flash.c files unnecessary; delete these.

This is for greater consistency with the ST application notes, which
refer to migrating "across" series (e.g. F1 to F2), but compatibility
"within" a family (e.g. F1).
So:
- Move libmaple/stm32x/include/family to .../include/series/ and fix
up includes appropriately.
- Refer to "family" headers as "series" headers in comments.
- Make similar "find and replace"-style changes to build system
variable names and comments.
- Move support/ld/stm32/family to .../stm32/series.
