441478d161 codecparsers: jpeg: hide gst_jpeg_scan_for_marker_code()
Make this function private for now, since it's unclear whether
it's actually needed seeing that gst_jpeg_parse() scans too.

d279e12c8f codecparsers: jpeg: fix and optimize scan for next marker code.
Fix scan for next marker code when there is an odd number of filler
(0xff) bytes before the actual marker code. Also optimize the loop
to execute with fewer instructions (~10%).

This fixes parsing for Spectralfan.mov.

41ed5c0266 codecparsers: jpeg: fix calculation of segment size.
The size of a marker segment is defined to be exclusive of any initial
marker code. So, fix the size for SOI, EOI and APPn segments but also
the size of any possible segment that is usually "reserved" or not
explicitly defined.
