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.

Remove SRAM_SIZE define. This seems like a bad idea given that
bootloader builds drop user code at an offset from the SRAM start
address.
Prefix every #define with "STM32_" to avoid polluting the namespace.
Keep and deprecate the remaining ones (except for aforementioned
SRAM_SIZE), but define them to be the same as their prefixed variant.
Take a little extra care to break libmaple builds which specify PCLK1
and PCLK2 instead of the prefixed versions. Some libmaple forks make
use of these; they will break in mysterious ways if they don't handle
this change properly.

For some unfathomable reason, Doxygen happily believes in PCLK2, but
but not PCLK1, so Breathe can't find the docs for PCLK1, and all the
children are unhappy. As a workaround, move all the Doxgyen crap into
__DOXYGEN_PREDEFINED_HACK sections immediately preceding the actual
definitions.

The delay_us() implementation multiplies its specified delay target by
a fixed constant in order to turn it into a busy-loop. This magic
number doesn't work properly when the clock configuration isn't the
same as a stock LeafLabs board. Add DELAY_US_MULT to the MCU-specific
configuration in stm32.h in order to allow other chips to use delay_us().

Put the PCLK1 and PCLK2 within #ifndef guards. This assumption is
biased towards LeafLabs boards.
