Merge remote-tracking branch 'qatar/master'
* qatar/master:
doxygen: Consistently use '@' instead of '\' for Doxygen markup.
Use av_printf_format to check the usage of printf style functions
Add av_printf_format, for marking printf style format strings and their parameters
ARM: enable thumb for Cortex-M* CPUs
nsvdec: Propagate error values instead of returning 0 in nsv_read_header().
build: remove SRC_PATH_BARE variable
build: move basic rules and variables to main Makefile
build: move special targets to end of main Makefile
lavdev: improve feedback in case of invalid frame rate/size
vfwcap: prefer "framerate_q" over "fps" in vfw_read_header()
v4l2: prefer "framerate_q" over "fps" in v4l2_set_parameters()
fbdev: prefer "framerate_q" over "fps" in device context
bktr: prefer "framerate" over "fps" for grab_read_header()
ALSA: implement channel layout for playback.
alsa: support unsigned variants of already supported signed formats.
alsa: add support for more formats.
ARM: allow building in Thumb2 mode
