0b25487cd1 jpegdec: don't overwrite the last valid line
If the the height is not a multiple of the macro block size then the memory
of the last line is reused for all extra lines. This is no problem if the
last line is duplicated properly. However, if the extra lines are not
initialized properly during encoding, then the last visible line is
overwritten with undefined data.
Use a extra buffer to avoid this problem.

addbc3c4ca jpegdec: add "max-errors" property to ignore decoding errors
Add property to ignore decoding errors. Default is to ignore a few
decoding errors if the input is packetized, but error out immediately
if the input is not packetized.

Ignoring errors for packetized input most likely doesn't work
properly yet, so don't do that for now.

7cbfe3eae1 jpegdec: fix memory leak
Don't leak result of gst_adapter_take(). There are most likely
smarter things we can do, but let's keep things simple for the
release.

Fixes #623172.

26e7fe27d7 jpegdec: only allocate as much temporary memory as needed for indirect decoding
When we can't decode directly into the output buffer, make our temp buffers
only as big as needed instead of allocating for the worst case scenario (well,
we still alloc more than strictly needed for some cases, but significantly
less than before).

e14bae6637 jpegdec: use slightly more adaptive formula for QoS
Should work at least a tad better if the decoder can't keep up, and
should also spread dropped frames a bit more evenly over time.

Original commit message from CVS:
* ext/jpeg/gstjpegdec.c: (gst_jpeg_dec_init), (gst_jpeg_dec_chain),
(gst_jpeg_dec_change_state):
* ext/jpeg/gstjpegdec.h:
Fix crashes/invalid memory access for pictures that have a height
that is not a multiple of 16 (or rather: v_samp_factor * DCTSIZE).
Also fix the state change function for downwards state changes
(need to chain up to parent before destroying our resources, to
make sure pads get deactivated and our chain function isn't
running and using those very same resources in another thread).
The jpeg line buffer only needs to be v_samp_factor*DCTSIZE lines
per plane, not picture_height lines; allocate that on the stack.

New mimetypes gone into effect today - this commit changes all old mimetypes over to the new mimetypes spec as described in the previous commit's document. Note: some plugins will break, some pipelines will break, expect HEAD to be broken or at least not 100% working for a few days, but don't forget to report bugs
