Move public headers to include directories; related cleanups.

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.
