Cleaned out libmaple.h; this had wide-ranging implications.
Many of the #defines in libmaple.h were board-specific, not MCU-specific. Most of these were only used by code under libmaple/usb/. These were moved into usb_config.h, and are clearly marked as being terrible hacks. I'm going to treat the USB stack as a black box that we'll deal with later. Further, instead of having a variety of #defines like "How many USARTS do I have?", we decide that based on the density of the chip. This is determined by testing for STM32_MEDIUM_DENSITY or STM32_HIGH_DENSITY defines. libmaple currently doesn't support low-density chips, so that suffices. The Makefile will set these automatically based on the MCU. Other offending #defines are ERROR_LED_PORT and ERROR_LED_PIN; these were made optional, but they're set in the Makefile as a hack to keep things working.
