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.
