iv decrypt handling code needs to be executed regardless of CONFIG_SMALL
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

This fix a bunch of "assignment from incompatible pointer type" warnings
with GCC.

Also fix some dates (use the commit date instead of the author date).

Note that a lavf bump was missing so I'm using 54.28.100 as a reference.

In CBC mode, when src=dst and we are decrypting a block different
from the first one, we need to save the current block of ciphertext
(which will constitute the initialization vector for the next block)
before we overwrite it.

This generalizes the previous work on disposition printing.

Disposition flags are shown in a dedicated section, which should improve
output intellegibility, extensibility and filtering operations.

This breaks output syntax with the recently introduced disposition
printing.

Do not make use of ad-hoc "tags" code, introduce a new section flag
SECTION_FLAG_HAS_VARIABLE_FIELDS to deal with the tags in a
content-agnostic way.

This is required by the pending disposition change.

It is similar to av_set_options_string() but accepts a list
of options that can be in shorthand: if the key is omitted
on the first fields, the keys from the shorthand list are
assumed, in order.

This fixes a theoretical signed overflow

Fixes Ticket1620
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

When decode_nal_units() previously encountered a NAL_END_SEQUENCE,
and there are some junk bytes left in the input buffer, but no start codes,
buf_index gets stuck 3 bytes before the end of the buffer.

This can trigger an infinite loop in the caller code, eg. in
try_decode_trame(), as avcodec_decode_video() then keeps returning zeroes,
with 3 bytes of the input packet still available.

With this change, the remaining bytes are skipped so the whole packet gets
consumed.

It is got_output, not data_size.

Avoids a forward declaration of decode_chunks().

The decode function assumes that the video will have those dimensions.
