Board-specific values; corresponding QA test generalizations.

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.
