It's not important whether the MCU is specified. What's important is
that <libmaple/stm32.h> gets everything it needs -- which it now
ensures that it does. Requiring people to do things on a per-MCU basis
hurts hackability and is just asking for trouble.
On the other hand, it's nice to provide a clue as to why
<libmaple/stm32.h> might be giving #errors, so do leave the
warnings. People can always hack the header to shut them up if they
want.

Feature-test macros for dealing with the fact that timer support has
holes. STM32_TIMER_MASK is a bitmask where bit n is set when TIMERn is
present. STM32_HAVE_TIMER(n) just tests whether bit n is set in
STM32_TIMER_MASK.
This is necessary because e.g. the STM32F100RB has timers 1-4, 6, 7,
and 15-17. Because of this, the usual STM32_NR_whatever won't work,
and we use a bitmask instead.
For F1 performance line (F103s), STM32_TIMER_MASK can be derived from
the density. For F1 value line, I'm not as sure, so just add it for
the single MCU we support (the STM32F100RB). Same story for F2: add it
for the STM32F207IC. We can fix this up later if necessary.

avr-gcc does it this way. Seems ok to me.

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.

There are five F1 lines in total. The necessary infrastructure for USB
access line (STM32F102 MCUs) support is missing, so add it.

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.

enum stm32_series gives a tag to each STM32 series, including the ones
we don't yet support.
STM32_MCU_SERIES is a define which the series stm32.h header must
provide, identifying the series of the MCU being targeted.

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.
