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.

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.

libmaple/dma.c defines DMA interrupts __irq_dma_channel[1-7],
consistent with what is specified by support/ld/names.inc. However,
names.inc is inconsistent with what support/ld/libcs3_stm32_src/
expects. Specifically, it contradicts the files
- support/ld/libcs3_stm32_src/stm32_isrs.S
- support/ld/libcs3_stm32_src/stm32_vector_table.S
Which use the names __irq_dma1_channel[1-7].
Change names.inc and dma.c to use the correct IRQ names.
The original names.inc/libcs3_stm32_src inconsistency was introduced
in 43d6921658cd29b8022af4424d340a90fbcb9a7f, but dma.c had the correct
names until ec3cf2903f4b03bc1dae5e159495c9e5ef0938ca, where they were
renamed for consistency with names.inc. At that point, DMA interrupts
stopped working. (This was documented in the commit message).
Thanks to forum user robodude666 for tracking this down.

Go through overlong source code lines and convert as many of them as
appropriate to be 80-column clean. This mostly affects license
headers. Overlong lines are determined by running following from the
libmaple base directory:
$ ack-grep --nocolor --nogroup --cpp --cc --ignore-dir=usb -- '.{80}'
Note that this excludes libmaple's usb subdirectory, which is still
full of ST code that doesn't follow the libmaple source code
guidelines.

completeness):

Simple USART receiver to SRAM buffer demo partially working.
Interrupting when buffer is full fails mysteriously. GDB thinks
we ended up in an STM32 reserved exception.

Add common linker scripts for ram and rom. Add medium and high density
libraries for libcs3.

This provides DMA, IWDG, PWR, and BKP support, and fixes several bugs.

Some bugfixes in the external interrupt code were found along the way.
Defines for nonexistent registers removed from nvic interface.

renamed SysTick_Handler back to SysTickHandler since all of our linker magic/lanchon-stm32 depends on that name. added backup register support in order to test independent watchdog support; it seems to work. next major test target is DMA support.
