The dynamic buffer does not contain the CRC32 element so calls to avio_tell()
don't take it into account. This resulted in CueRelativePosition values being
six bytes short.
This is a regression since 6724525a15
Instead of adding yet another custom check for CRC32 to fix a size or an offset,
remove the existing ones and reserve the six bytes in the dynamic buffer.

Some people seem to oppose this the patch seems to have been missed for a month on the ML
lets restart the discussion and solve this after the release
This reverts commit e936c8d176.
Allowing larger timestamps makes it impossible to calculate basic things like the
difference of 2 timestamps or their sum without checking each individual computation for
overflow.
This should avoid a significant number of overflow checks

3 parts:
- Supports multiple chapter streams
- Exports regular text chapter streams as opaque data. This prevents consumers
from showing chapters as if they were regular subtitle streams.
- Exports video chapter streams as thumbnails, and provides the first one as
an attached_pic.
This allows a consumer to run the muxer's init function without actually
writing the header, which is useful in chained muxers that support
automatic bitstream filtering.
It is negative, so can't be used for left shifting.
This fixes ubsan runtime error: shift exponent -1 is negative

Add new mime types AAL2-G726 for g726 as suggested in rfc 3551.
This patch will break interaction with applications that incorrectly
use big-endian G.726 with mime type G726 but we know of at least one

If probe_codec is called with pkt == NULL, it sets probe_packets to 0
and request_probe to -1.
However, request_probe can change when calling s->iformat->read_packet
and thus a probe_packets value of 0 doesn't guarantee a request_probe
value of -1.
In that case calling probe_codec again is necessary to prevent
triggering the assert.

- codec copy apparently required by bitstream filters

This is mostly useful for muxers that wrap other muxers, such as dashenc

but delaying the header can cause problems when the muxer intended the header
to be written to a separate file.
