Fix possible crash when long_name is not defined (for example if
--enable-small).

Possibly safer.

Previously when saturation was reinited, the old value was freed when
setting options, and freed again in PARSE_EXPRESSION().

Avoid possible segmentation fault if codec_long_name is defined as
NULL (for example if --enable-small).

Fixes bug 372.

The Apple assembler refuses to assemble the 3-operand form
in Thumb2 even though it is valid syntax.

When building Thumb2 code, the end of a function, where the PIC
offsets are placed, need not be aligned.  Although the values
are only accessed with instructions allowing unaligned addresses,
keeping them aligned is preferable.

v5.0 of the TI ARM compiler changes the version string.

This occurs with fuzzed mpeg-ts files. set_codec_from_probe_data() is
called with a zeroed AVProbeData since no packet made through for
specific stream.

Previously the device was returning EOF when the first sink was ending,
with the current change the device will continue to return frames until
all the sinks are EOF, which seems the most expected behavior.

Compute duration in microseconds, rather than in timebase units. Decrease
approximation errors.

Inline functions declared without extern do not provide an external
definition in standard C99.  This code only works because most
compilers do not implement the inline semantics correctly.  With a
stricter compiler, linking fails with unresolved references to these
functions.

Declaring the functions extern inline works correctly with some
compilers while some others still fail to create external definitions.

For maximum portability, create a static inline version with an
externally visible wrapper for ff_get_mb_score.  ff_epzs_motion_search
is so large that no sane compiler inlines it anyway, so there the
inline keyword can simply be dropped with no effect.
