The actual usefulness of the hack is not known, and it does cause
infinite loops with some broken input files.

Previously, s->context_initialized was left set to 1
if ff_vc1_decode_init_alloc_tables failed, skipping the
initialization completely on the next decode call.

Fragmenting blindly to a certain duration isn't a good choice
if one should be able to switch between different qualities,
therefore default to keyframes instead.

This makes sure other sanity checks for conflicting options
can work properly, e.g. for the conflict between the faststart
flag when using the ismv mode.

Use update_offset() as done for rtmp audio, video and notifications and
read update and write the fields instead of replacing them in the rtmp
packet and then memcpying it to the output buffer.
And fix the AMF_DATA_TYPE_ARRAY parsing while at it.
A MIXEDARRAY type, as the ARRAY, store the number of elements in
an uint32 before the list. The ARRAY is strict and does not have
an OBJECT terminator, MIXEDARRAY behaves like an OBJECT type and
a different than stated number of element can be present.
Prior to this on msvc/icl there was no handling of deprecated functions
and the deprecated warning was disabled.
After enabling there are a number of warnings relating to the CRT and
the use of the non-secure versions of several functions. Defining
_CRT_SECURE_NO_WARNINGS silences these warnings.

Also make sure the existing length check can't overflow.

This makes sure that it doesn't try to free an AVBuffer belonging
to an earlier packet when we free the local packet at the end.

If the height is zero, the decompression will probably end up
failing due to not fitting into the allocated buffer later
anyway, so this doesn't need any more elaborate check.

Null buffers are useful for simulating writing to a real buffer
for the sake of measuring how many bytes are written.
