Fixes the corner case in which the internal buffer size
is larger than input buffer provided and resizing it
before moving the left over samples would make it write
to now unallocated memory.

The existing check has two problems:
 1) i + count can overflow, so that the check '< 256' returns true.
 2) In the (i == 'N') case occurs a j-- so that the loop runs once more.

This can trigger the assertion 'nut->header_len[0] == 0' or cause
segmentation faults or infinite hangs.

If a PAT is finished while a PMT section filter is opened but
not yet finished, the PMT section filter is closed and all
the received data is discarded.

This is usually not an issue but some multiplexers (With very
quick PAT/PMT repetition settings) consistently emit a PMT
section start, then a PAT, and then the rest of the PMT,
causing the aforementioned behavior to result in no PMT being
finished.

In the most pathologic situation the stream information are lost
and the probe fallback miscategorizes subtitles as mp3 audio.

Avoid the issue through eliminating redundant PSI/SI table
updates by checking their version field, which is required by
the standard to be incremented on every change no matter how
minor.

Check extended sync word for 16-bit LE and BE core streams to reduce
probability of alias sync detection. Previously sync word extension was
checked only for 14-bit streams.

This follows up the similar change in avcodec/dca_parser.

Fixes a memory leak on init failure.

Convert exisiting free functions to av_freep() to avoid accidental
double frees, and always intialize all buffers to NULL.

This avoids allocating/freeing memory at every function call,
checking its return value, and carrying the error around.

s->decoded_buffer is allocated with a min_size of:
    2 * FFALIGN(blockstodecode, 8) * sizeof(*s->decoded_buffer)

Then it is assigned to s->decoded[0] (and s->decoded_buffer + FFALIGN(blockstodecode, 8)
to s->decoded[1]) and passed as out buffer to decode_array_0000.

In this function 64 elements of the out buffer are written
unconditionally and outside the array if blockstodecode is too small.

This causes memory corruption, leading to segmentation faults or other
crashes.

Thus change decode_array_0000 to write at most blockstodecode elements
of the out buffer.

AVOpenCLDeviceNode and AVOpenCLPlatformNode used fixed static buffer for holding the device and platform name.
This patch modifies these structures to use pointers instead. The memory required to hold the names is
now dynamically allocated, the size for which is determined by querying appropriate OpenCL runtime APIs.

The opt_opencl_bench function copied the device name using strcpy without checking if the source string was larger.
This patch fixes this by replacing the strcpy with av_strlcpy, with the string copy size capped to the destination buffer size.

Remove the direct profile from UTCTiming element. Per DASH spec,
direct profile value should be the time at which the request was
made to the server and not the time at which the manifest was
written. So ffmpeg cannot write this value. This patch removes
the direct profile and write the UTCTiming element with the http
profile only if a URL is passed as a parameter. Update the fate
test to reflect this change.

This will test properly CRLF with make fate, make fate-subtitles and any
make fate-sub-* test. Before this commit, the rawdiff was triggered only
by make fate-subtitles.

Also make sure fate-sub-* only match the tests relying on fmtstdout
command, to at least avoid failing on MingW. See
