While Vulkan itself went more or less the way it was expected to go,
libvulkan didn't quite solve all of the opengl loader issues. It's multi-vendor,
yes, but unfortunately, the code is Google/Khronos QUALITY, so suffers from
big static linking issues (static linking on anything but OSX is unsupported),
has bugs, and due to the prefix system used, there are 3 or so ways to type out
functions.
Just solve all of those problems by dlopening it. We even have nice emulation
for it on Windows.
VkPhysicalDeviceLimits.optimalBufferCopyRowPitchAlignment and
VkPhysicalDeviceExternalMemoryHostPropertiesEXT.minImportedHostPointerAlignment are of type
VkDeviceSize (a typedef uint64_t).
VkPhysicalDeviceLimits.minMemoryMapAlignment is of type size_t.

According to the PES packet definition defined in Table 2-17 of ISO_IEC_13818-1
specification, some fields like PTS/DTS or pes_extension could only appears if
the stream_id meets the condition:
if (stream_id != 0xBC && // program_stream_map
stream_id != 0xBE && // padding_stream
stream_id != 0xBF && // private_stream_2
stream_id != 0xF0 && // ECM
stream_id != 0xF1 && // EMM
stream_id != 0xFF && // program_stream_directory
stream_id != 0xF2 && // DSMCC_stream
stream_id != 0xF8) // ITU-T Rec. H.222.1 type E stream
And the following stream_id types don't have fields like PTS/DTS:
else if ( stream_id == program_stream_map
|| stream_id == private_stream_2
|| stream_id == ECM
|| stream_id == EMM
|| stream_id == program_stream_directory
|| stream_id == DSMCC_stream
|| stream_id == ITU-T Rec. H.222.1 type E stream ) {
for (i = 0; i < PES_packet_length; i++) {
PES_packet_data_byte
}
}
Current implementation skipped the check of stream_id causing some kind of
streams like private_stream_2 to be incorrectly written with actually a
private_stream_1-like PES header with PTS/DTS field. For example, Japan DTV
transmits news and alerts through ARIB superimpose that utilizes
private_stream_2 still could not be remuxed correctly for now.
This patch set fixes the remuxing for private_stream_2 and
other stream_id types.

AVCodecContext.extradata is freed generically by libavcodec for
encoders, so it is unnecessary for an encoder to do it on its own.

Was added in error very early on, passing in only the required fields.
Later, the muxer and demuxer were changed to pass the entire APMState
struct as extradata.
Technically a breaking change, but this was only around for a *very* short
time before it was updated,

Compared to the earlier behaviour the following changes:
a) AVCodecInternal.byte_buffer is freed.
b) The last_pkt_props FIFO is emptied before freeing it.
c) If set AVCodecContext.hwaccel is uninitialized and its private data
is freed; hw_frames_ctx and hw_device_ctx are also unreferenced.
d) coded_side_data is freed.
e) active_thread_type is reset.
a), b), d) should be no-ops as the buffer/fifo should be empty and
no coded_side_data should exist at any point of avcodec_open2().
e) is obviously not bad.
c) is in accordance with the documentation of hw_(frames|device)_ctx
which states that libacodec takes over ownership of these references.
At least in the case of VC-1 it is possible for the hw acceleration to
be set during init and in this case freeing it actually fixes a memleak.
avcodec_close() needed only minor adjustments to make it work with
a potentially not fully initialized codec.

Right now all AVCodecContexts except those using frame-threaded decoding
call the codec's init function and expect its close function to be
called. In order to make sure that the close function is not called for
frame-threaded decoding ff_frame_thread_free() resets
AVCodecContext.codec (and because of this it has to free the private
AVOptions of the main AVCodecContext itself). This is not obvious and
potentially fragile. Instead add a field to AVCodecInternal that
indicates whether close should be called for this AVCodecContext.
It is always zero when using frame-threaded decoding, so that resetting
the codec is no longer necessary and has been removed.

The frame_thread_encoder has so far not been freed in case an error
happened in avcodec_open2() after ff_frame_thread_encoder_init().

Given that the AVCodec.next pointer has now been removed, most of the
AVCodecs are not modified at all any more and can therefore be made
const (as this patch does); the only exceptions are the very few codecs
for external libraries that have a init_static_data callback.
