This disables everything that was deprecated at least 18 months ago.

Readjust the minimum API version as needed, postponing any
API-incompatible changes until the next bump.

Hook up all attributes that don't have a MSVC specific version at the
moment.

See f637046d for details.

These don't seem to be critical for building with clang in MSVC mode
though, and thus haven't been hooked up until now.

These seem to build fine with as old clang as 3.3 at least.
(clang 3.3 disguises itself as gcc 4.2 normally, so all of these
have been used for clang before, except for av_cold.)

The clang version numbers themselves are useless for detecting what
attributes are available, since Apple's clang builds use a completely
different versioning (presenting itself as e.g. clang 8.0 instead
of 3.8).

This is a follow-up to f637046d.

Without the noreturn attribute set, avconv_opt.c fails to build after
d2e6dd32 with the error "control may reach end of non-void function".
By making sure the noreturn attribute is set properly, this compiles
as intended.

Having a mismatch between the number of channels in the stream and those
in the channel map will lead to a segfault or worse.

Make easier to handle the polling function before we implement
full threading support.

JACK is not commonly installed and should not be picked up as a
dependency unless specifically requested.

This supports retrieving the device from a provided hw_frames_ctx, and
automatically creating a hw_frames_ctx if hw_device_ctx is set.

The old API is not deprecated yet. The user can still use
av_vdpau_bind_context() (with or without setting hw_frames_ctx), or use
the API before that by allocating and setting hwaccel_context manually.

This "reuses" the flags introduced for the av_vdpau_bind_context() API
function, and makes them available to all hwaccels. This does not affect
the current vdpau API, as av_vdpau_bind_context() should obviously
override the AVCodecContext.hwaccel_flags flags for the sake of
compatibility.

Not yet enabled for any hwaccels.

Adds functions to convert to/from strings and a function to iterate
over all supported device types.  Also adds a new invalid type
AV_HWDEVICE_TYPE_NONE, which acts as a sentinel value.

Creates a new device context from another of a different type which
refers to the same underlying hardware.

The rtmpcrypt protocol requires it.

Align the second/third operands as they usually are.

Due to the wildly varying sizes of the written out operands
in aarch64 assembly, the column alignment is usually not as clear
as in arm assembly.

Minor cosmetic changes by committer.
Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

Jack uses weak symbols on purpose.

Also do some small cosmetic changes: Drop pointless _MMX suffix from ABSD2
macro name, drop pointless check for MMX support, we always assume MMX is
available in our SIMD code, fix spelling.

Section 9.2.3.2 of the spec implies that run_before must not be larger
than zeros_left.

Fixes invalid reads with corrupted files.

The code does some nontrivial jumping around in the buffer, so it is
safer to use a checked API rather than do everything manually.

Fixes a bug in nalff parsing, where the length field is currently not
counted in the buffer size check, resulting in possible overreads with
invalid files.

In the half/quarter cases where we don't use the min_eob array, defer
loading the pointer until we know it will be needed.
Signed-off-by: Martin Storsjö <martin@martin.st>

This reduces the number of lines and reduces the duplication.

Also simplify the eob check for the half case.

If we are in the half case, we know we at least will need to do the
first three slices, we only need to check eob for the fourth one,
so we can hardcode the value to check against instead of loading
from the min_eob array.

Since at most one slice can be skipped in the first pass, we can
unroll the loop for filling zeros completely, as it was done for
the quarter case before.

This allows skipping loading the min_eob pointer when using the
quarter/half cases.
