e0c49a7590 jpegenc: Keep variables in sane state after _reset 
When reseting, keep 'row' variables at a sane state after
freeing to avoid it being freed again on _resync realloc
when the element is reused.

Fixes #619943

3cfd7968b4 jpegdec: increase acceptable output sizes 
We can perfectly decode 1x1 images so lower the min width and height to 1.

Fixes #618392

566bd22435 jpegenc: also lift the arbitrary restrictions for width and height 
This was already done for jpegdec.

52c71352e0 jpegdec: optimise buffer scanning 
Specifically, when needing more data, do not rescan from start next time
around, but resume from last position.

cec48383b1 jpegdec: more sanity checks on input 
Specifically, verify input components / colour space is as code
subsequently expects, thereby avoiding crashes or otherwise bogus output.
Presently, that means 3 components YCbCr colour space, and somewhat
limited sampling factors.

Fixes #600553.

6b2a0c7c46 jpegdec: don't crash if jpeg image contains more than three components 
Our code currently only handles a maximum of 3 components, so error
out for now if the image has more components than that.

Fixes #604106.

b1984b72bb jpegenc: Fix getcaps function 
When creating the caps allowed to upstream using downstream
restrictions, use gst_pad_get_allowed_caps as that has the
usable formats and puts into it the width, height and framerate
fields. This avoids getting errors about getcaps returning
non subset caps of its pad template.

This error showed up on the metadata plugin unit test in -bad.

74ac172bc2 jpegenc: should not return caps ANY based on downstream 
When downstream has a sink pad with ANY caps, jpegenc should
treat it the same as NULL and return its template caps.

Fixes #614842

Raimo Järvi
10f092dc61 jpegenc: Set correct getcaps/setcaps functions on srcpads and simplify them 
This fixes downstream negotiation, upstream negotiation isn't really
supported by jpegenc yet.

Fixes bug #613789.

384c4a2495 jpegdec: reset segment info after flush 
Reset the segment info after a flush. We use the segment for handling QoS and if
we don't reset the segment, QoS is basically disabled after a flushing seek.

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).

87bd79f4ba jpegdec: fix bogus warning about discont flag on first buffer 
The very first buffer should always have the DISCONT flag set, no
need to warn about that. Only warn if we get a DISCONT buffer in
non-packetised mode and we already have some data.
