This will allow for easier implementation of ARM-optimized functions in
libraries other than libavcodec.

This adds some macros simplifying Thumb and pre-v6T2 compatibility.

Due to apprent bugs in the GNU assembler and/or linker, relocations
can be incorrectly processed if the alignment of a Thumb instruction
is changed in the output file compared to the input object.

This fixes crashes in h264 decoding with Thumb enabled. No effect in
ARM mode since everything is 4-byte aligned there.

This prevents build errors when compiler and assembler default
targets differ.  Ideally each file would declare the highest
level it requires.  This is however not easily possible as it
complicates assembling pre-armv6t2 code in Thumb-2 mode.

HAVE_NEON is used as indicator for ARMv7-A since no other
symbol exists for this and NEON is only available in this
variant.

From 52.503s (~40fps) to 27.973sec (~80fps) decoding of 480p sintel

This enables UAL syntax for all asm files instead of only those
which happen to be incompatible with the old, deprecated syntax.

Apparently Apple platforms do not handle movw/movt relocations
properly, leading to runtime crashes in code using them.

This ensures code always goes into the .text section and avoids the
need to specify it explicitly after changing sections.

Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
