The patterns in GCC_CXX_INCLUDE_PATTERNS are tested in order from first
to last and the first matching pattern is used instead of the last.
The latest version within each pattern will be selected, like before, to
get the most recent tool chain version.

atmega_common: disable interrupts prior to rebooting
...
If the watchdog is being reset in another thread, then
the reboot will never take place. This commit disables interrupts prior
to setting the watchdog timer to 250ms. This functionallity was common
to all Atmega CPUs, so it was moved to atmega_common.

cpu/sam21: removed superfluous gpio_init_sercom
...
This function was a duplication of the existing gpio_init_mux,
where the exiting function is the more general one, as the mux
inititalization is not only valid for the sercom module...

periph/i2c: convert char to uint8_t where applicapable
...
In general, data transferred through I2C are bytes and thus should have
type uint8_t, not char.
Also convert uint8_t ptrs to void ptrs

boards: add support for SODAQ Autonomo
...
The following features were tested (briefly):
* UART (the first)
* I2C using a BMP180 on a SODAQ TPH board
* SPI0, connected to the on-board serial data flash (only DevID was read
using the periph_spi test program)
* xtimer is working (it's the same code as in samr21)

cpu/sam21_common: add samd21 include files from ASF CMSIS
...
This adds support for all samd21 variants. Notice that the previous samd21
was moved to cpu/samr21
To use this cpu variant you must set at least the following in your boards
Makefile.include:
export CPU = samd21
export CPU_MODEL = samd21j18a # Not sure if this is used
CFLAGS += -D__SAMD21J18A__ # or whatever variant you have
The samd21 include files were copied from ASF 3.30
