69151f6850 jifmux: Make it more colorspace smart 
This makes it able to recombine rgb images, making it possible
to add tags to rgb jpegs as well.

Uses a simple strategy to check what are the possible colorspaces
and avoid adding jfif to ones that aren't YUV/Gray.

27333b0ef2 jifmux: Do not limit the size of the image on 16bits 
Use guint instead of guint16 to represent the size of the encoded image,
this would make some recombined images lose most of their data and
show like a big black image with a small line of content on top.

Also adds a minor log message.

pushed downstream.

d49acb5588 jifmux: Detect EOI correctly 
EOI are not always at the last 4 bytes. We need to search
the last 5 bytes to find the 0xFFD9 sequence as jpegenc seems
to round the buffer size to the next 4 multiple.

ba15ad9387 jifmux: Put APP0 first always

be first.

407f615887 jifmux: Avoid recombining RGB jpegs 
JFIF only allows YUV as colorspace, when we receive an RGB jpeg,
we should just push it forward without adding the JFIF marker.

Fixes #627413

In particular, this makes the jpegparse unit test pass again.
Also add a debug statement.

Fixes #622690.

20a8666388 Revert "jifmux: Merge xmp and tagsetter tags." 
This reverts commit 4e5c412234.

jifmux shouldn't be able to handle jif and shouldn't expect
any xmp on its data. So, no need to handle them.

parse them and merge with the tagsetter ones.

reject buffers without caps.

jifmux was only appending a new xmp packet to the stream,
it should replace if there is already one.

d68a4c1dcc jpegparse: improve buffer scanning 
Specifically, when scanning for entropy data segment length and needing
more data, do not rescan from start next time around, but resume at
last position.

f3122f2b30 jpegparse: provide a getcaps function for src pad and improve setcaps 
Previously jpegparse was failing in decodebin as the caps we were setting where not
setting all caps fields. We need the own getcaps function to report what we actualy
accept.
