Still a polling driver, but the libmaple proper interface exposes
enough that users enable the various interrupts and define their own
IRQ handlers if they feel like it.
Wirish HardwareSPI interface was largely redone; it's more like the
Arduino implementation now, although there are some differences when I
didn't like their API. The old methods are still there, but are
deprecated and slated for deletion in 0.1.0.
New board-specific values: BOARD_NR_SPI, BOARD_SPIx_NSS_PIN,
BOARD_SPIx_MOSI_PIN, BOARD_SPIx_MISO_PIN, and BOARD_SPIx_SCK_PIN, for
x from 1 to BOARD_NR_SPI.
Documentation was updated appropriately.

- gpio.h: afio_mapr_swj_config() renamed afio_cfg_debug_ports()
- [new] wirish_debug.h: disableDebugPorts(), enableDebugPorts()
- Maple, Maple Native, and Maple RET6 PIN_MAPs are now larger by 5,
have mappings for the extra JTAG/SW pins.
Documentation was updated appropriately.

Various board-specific #defines and arrays of pins added.
For the changelog (some of this information predates this commit):
* wirish/boards.h now declares the following arrays of pin numbers:
* boardPWMPins - PWM-capable pins
* boardADCPins - ADC-capable pins
* boardUsedPins - pins already in use, e.g. BOARD_BUTTON_PIN
It also declares a bool boardUsesPin(uint8 pin) function for
convenient testing of whether a pin is in use.
* wirish/boards/*.h now define:
* BOARD_USART1_TX_PIN
* BOARD_USART1_RX_PIN
* BOARD_USART2_TX_PIN
* BOARD_USART2_RX_PIN
* BOARD_USART3_TX_PIN
* BOARD_USART3_RX_PIN
* BOARD_NR_GPIO_PINS (renamed from NR_GPIO_PINS)
* BOARD_NR_USARTS (renamed from NR_USARTS)
* BOARD_NR_PWM_PINS
* BOARD_NR_ADC_PINS
* BOARD_NR_USED_PINS
* wirish/boards/maple_native.h now defines:
* BOARD_UART4_TX_PIN
* BOARD_UART4_RX_PIN
* BOARD_UART5_TX_PIN
* BOARD_UART5_RX_PIN
(Unfortunately, wirish/boards/maple_RET6.h cannot, since at least
one of the UART4/UART5 pins are used already; this will require layout
changes for a wide-release Maple form factor RET6 board).
* wirish/boards/*.cpp all include the corresponding array definitions.
They all live in flash by default, thanks to the new __FLASH__ macro
in wirish/wirish_types.h, which is a synonym for the existing __attr_flash
#define in libmaple/libmaple_types.h.
The documentation was updated to include this information. It also
gained various FIXME/TODO comments related to its generalization
across boards.
The quality assurance-related examples (examples/qa-slave-shield.cpp
and examples/test-session.cpp) now make heavy use of board-specific
values to ensure portability.

/wirish/boards/ contains xxx.h and xxx.cpp (for xxx=maple,
maple_native, maple_mini, maple_RET6). The headers contain the
board-specific #defines that used to live in boards.h (except
BOARD_INIT, which was removed). The CPP files contain the PIN_MAP
definitions that used to live in boards.cpp, and a proper boardInit()
function to replace the old BOARD_INIT macro. This will make it
easier to add new boards in the future.
struct PinMapping was renamed struct stm32_pin_info, and was moved
into a new wirish_types.h. Its external interrupt field was moved
into struct gpio_dev, which saves memory by storing an afio_exti_port
per port, rather than one per pin. Also rearranged the stm32_pin_info
fields to improve packing. Maple's PIN_MAP is now down to below 500
bytes.
