This check is redundant with the previous commit but it provides
better error messages and feedback while the previous commit
ensures that var_read_string() doesnt return uninitialized arrays
if it itself is feeded with an invalid size possibly through a
different future codepath.

should be the raw amount of pixels (for example 3840x1080 for full HD side by
side) and the DisplayWidth/Height in pixels should be the amount of pixels for
one plane (1920x1080 for that full HD stream)."
So, move the aspect ratio check in the mkv_write_stereo_mode() function
and always write the embl when stereo format and/or aspect ration is set.
Also add a few comments to that function.

While a standalone implementation is nice, we already depend on
gmtime and gmtime_r in a number of places.

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).

If the buffer provided to strftime is too small, the buffer contents
are indeterminate - it does not guarantee actually null terminating
the buffer.

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.

The new function wraps errno so that its value is correctly reported
when other functions overwrite it (eg. in case of logging).
