The encoder has its own tables and does not access the idct_factor
member of the DVVideoContext structure.

The coefficients must be in the appropriate zigzag scan order.
Also fix their values at the same time, as they were pretty wrong.
Fixes ticket #2970.

Conflicts:

Merged-by: Michael Niedermayer <michaelni@gmx.at>
While a standalone implementation is nice, we already depend on
gmtime and gmtime_r in a number of places.

If it isn't available in the system, we've got a fallback to
the normal localtime function, so normal code can assume it is
available as long as time_internal.h is included.

gmtime isn't thread safe in general. In msvcrt (which lacks gmtime_r),
the buffer used by gmtime is thread specific though.
One call to localtime is left in avconv_opt.c, where thread safety
shouldn't matter (instead of making avconv depend on the libavutil
internal header).

This allows writing most code as if they always are is available.
These are ok to use from other libraries even though it's not a
public header, since they only provide an inline declaration, and
doesn't add an actual dependency on lavu internals. (This can be
considered more a build system compatibility fallback than a
libavutil feature.)

If the buffer provided to strftime is too small, the buffer contents
are indeterminate - it does not guarantee actually null terminating
the buffer.
Signed-off-by: Martin Storsjö <martin@martin.st>
It is derived from the actual equations of the specs. In
particular, it is closer to the inverse of what the encoder uses.
fate tests accordingly updated.

flac_picture: prevent a possible out of bound write
This is only partly merged, the condition this checks for
is impossible to be true as it would imply avio_read() to
read more than the size passed to it

None of these are likely unless the user is writing a file with two billion
streams or a duration of around two months.
