Up until now, writing the data of a slice uses an intermediate buffer
into which the unit (both header as well as the rest) is assembled
before being copied into a freshly allocated buffer. But given that one
has a very good upper bound on the size needed before one starts copying
the slice data,
The number of bits in a PutBitsContext must fit into an int, yet the
various cbs functions to write units did not check that the argument in
init_put_bits is in the range 0..INT_MAX / 8. This has been changed.
Furthermore, the check 8 * data_size > data_bit_start that there is
data beyond the
The earlier requirement was for the new buffer to be bigger than the old
one. This has been relaxed to only demand that the new buffer can hold
all the data written so far. This is in preparation for further commits.

In scearios where a Temporal Unit is written right after reading it using the
same
CBS context (av1_metadata, av1_frame_merge, etc), the reference frame state used
by the writer must not be the state that's the result of the reader having
already
parsed the current frame in question.

Since flushing can now also be signalled by sending an empty packet
(a packet without (side-)data), it is unnecessary to explicitly send
NULL as packet to flush the bitstream filters.
