When the packet size is known in advance like here, one can avoid
an intermediate buffer for the packet data by using
ff_get_encode_buffer() and also set AV_CODEC_CAP_DR1 at the same time.

When the packet size is known in advance like here, one can avoid
an intermediate buffer for the packet data; this also makes it easy
to allow user-supplied buffers. Only one thing needed to be changed:
One can no longer use a pointer to uint16_t for the destination buffer
because its alignment is unknown.

Up until now, the cljr encoder used buffers that were too big by a
factor of eight (probably bit/byte confusion). This has been fixed.
And because the needed buffer size can be easily calculated in advance,
one can avoid the implicit use of an intermediate buffer and can even
allow user-supplied buffers.

The size of the output buffer is always known in advance and
the code has no alignment requirement (it uses mostly the PutBits API),
so allowing user-supplied buffers is trivial.

There are cases where using 1000 as the MP4 timescale is not
accurate enough, for example when one needs sample-accurate audio
handling.
This adds a new AVOption to the MOV/MP4 muxer to override the
movie timescale, but it still defaults to 1000 to maintain current
default behavior.

The MLP/TrueHD encoder uses pointers to non-const to access several
static objects that are only initialized at runtime and are therefore
not declared as const. This does not result in compiler warnings, but it
is fragile, as these objects are really not to be modified as they are
not owned by any encoder instance. Therefore this commit adds const to
the pointed to type of the pointers used to access them after their
initialization. One object has even been made const.
