That code is only ever initialized with that flag set.

Fixes valgrind warning "Conditional jump or move depends on
uninitialised value(s)." from avio_flush().

The current code will ignore the init_get_bits() failure and do an
invalid read from the uninitialized GetBitContext.

It does not break anything currently, but should not be done anyway.

This fixes retrieving a valid profile for many of the FATE conformance samples,
allowing them to be properly decoded by the HWAccel after adding a profile check.

These bits are set by exceptions in NEON instructions.

Also print the differing bits when FPSCR is clobbered,
and use bic instead of lsl, for clearing the topmost bits.

Fixes AS error on non NEON builds introduced in 71a04721. Also
set the fpu directly to vfp in checkasm.S to cause build errors on NEON
builds.

Each const block needs to be terminated by one endconst
invocation so either call endconst after each, or just
declare plain labels to the later strings.

This fixes errors such as this, on some binutils versions:

checkasm.S:38: Error: Macro `endconst' was already defined

Since we only know whether a NAL unit corresponds to a new field after
parsing the slice header, this requires reorganizing the calls to slice
parsing, per-slice/field/frame init and actual decoding.

In the previous code, the function for slice header decoding also
immediately started a new field/frame as necessary, so any slices
already queued for decoding would no longer be decodable.

After this patch, we first parse the slice header, and if we determine
that a new field needs to be started we decode all the queued slices.

This function's purpose is not very well defined. Currently it does two
(only marginally related) things: selecting the next output frame and
calling ff_thread_finish_setup() for frame threading. The first of those
more properly belongs under field_start(), while the second can be
called directly from decode_nal_units().

Also set FF_CODEC_CAP_INIT_THREADSAFE while adding internal capabilities.
