This won't work on F2, which at times has SDA and SCL on different
ports (e.g. I2C3 SDA on PC9, SCL on PA8). Add .sda_port and .scl_port
replacements, which are used when the now-deprecated .gpio_port is
null. Use them correctly everywhere, with some new i2c_private.h
helper functionality.
Sigh. The F1 I2C code tries too hard to guess what you wanted; it's
not porting well at all.

Do this via new private _i2c_set_ccr_trise().

This is ad-hoc and nonportable. If you really want I2C mapped
elsewhere, then mess with the I2C device fields and call afio_remap()
yourself. (This is also cleaner for F2).

The IRQ priority hack is unnecessary on targets with properly
functioning I2C IRQ handlers, so we shouldn't use it unless we have
to. Add a mechanism so a series header can provide such a hack if
necessary. Have the F1 series header use this mechanism.

I'm going to be moving a lot of code around without changing it soon,
so git blame will be unreliable.

These are necessary to pull out some calls to gpio_set_mode().

Calling throb() directly like that breaks the abstraction.

Bring back <libmaple/i2c.h> support on STM32F1 with a view towards how
it'll be implemented on STM32F2. There are still many F1-isms in
libmaple/i2c.c and <libmaple/i2c.h>, to be dealt with subsequently.
Move device declarations and base pointer definitions to a new F1
<series/i2c.h>. The register maps and bit definitions themselves are
identical on both series, so leave them in the libmaple header.
Add i2c_private.h, which contains:
- I2C_DEV(), a convenience macro for defining an i2c_dev, and
- declarations for the event and error IRQ handlers.
The IRQ handlers are large, and I2C is slow anyway, so I see no reason
to make them inline in the private header (as we do for some other
peripherals). We just expose the existing ones that were formerly
static in libmaple/i2c.c, but prefix the names with underscore.
Move the device declarations and IRQ handlers into new
stm32f1/i2c.c. These use the i2c_private.h API.

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.

Move libmaple/*.h to (new) libmaple/include/libmaple/. The new
accepted way to include a libmaple header foo.h is with:
#include <libmaple/foo.h>
This is more polite in terms of the include namespace. It also allows
us to e.g. implement the Arduino SPI library at all (which has header
SPI.h; providing it was previously impossible on case-insensitive
filesystems due to libmaple's spi.h).
Similarly for Wirish.
The old include style (#include "header.h") is now deprecated.
libmaple/*.h:
- Change include guard #defines from _FOO_H_ to _LIBMAPLE_FOO_H_.
- Add license headers where they're missing
- Add conditional extern "C" { ... } blocks where they're missing
(they aren't always necessary, but we might was well do it against
the future, while we're at it.).
- Change includes from #include "foo.h" to #include <libmaple/foo.h>.
- Move includes after extern "C".
- Remove extra trailing newlines
Note that this doesn't include the headers under libmaple/usb/ or
libmaple/usb/usb_lib. These will get fixed later.
libmaple/*.c:
- Change includes from #include "foo.h" to #include <libmaple/foo.h>.
Makefile:
- Add I$(LIBMAPLE_PATH)/include/libmaple to GLOBAL_FLAGS. This allows
for users (including Wirish) to migrate their code, but should go
away ASAP, since it slows down compilation.
Wirish:
- Move wirish/**/*.h to (new) wirish/include/wirish/. This ignores
the USB headers, which, as usual, are getting handled after
everything else.
- Similarly generify wirish/boards/ structure. For each supported
board "foo", move wirish/boards/foo.h and wirish/boards/foo.cpp to
wirish/boards/foo/include/board/board.h and
wirish/boards/foo/board.cpp, respectively. Also remove the #ifdef
hacks around the .cpp files.
- wirish/rules.mk: put wirish/boards/foo/include in the include path
(and add wirish/boards/foo/board.cpp to the list of sources to be
compiled). This allows saying:
#include <board/board.h>
instead of the hack currently in place. We can allow the user to
override this setting later to make adding custom board definitions
easier.
- Disable -Werror in libmaple/rules.mk, as the current USB warnings
don't let the olimex_stm32_h103 board compile. We can re-enable
-Werror once we've moved the board-specific bits out of libmaple
proper.
libraries, examples:
- Update includes accordingly.
- Miscellaneous cosmetic fixups.

stm32.h has been updated to prefix its definitions. Update the rest
of libmaple to take this into account.

Changes to struct i2c_dev members:
- uint8 clk_line's type is changing and is being renamed, is now
rcc_clk_id clk_id
- uint8 ev_nvic_line's type is changing to nvic_irq_num
- uint8 er_nvic_line's type is changing to nvic_irq_num
Previous names were badly typed and inconsistent with the rest of
libmaple.
Exposing i2c_init(), also for consistency.
Adding/editing many Doxygen comments, for documentation and general
housekeeping.

10-bit slave addressing is untested until I have a device that speaks
such.
