f9845d0266 flacparse: Improve header validity checks
Allow sample rate, number of channels and bps to change and in that case update
the caps accordingly.

Also move (non-fatal) validity checks and storing of the header values outside
the actual parsing once we actually know that a valid frame is available.

And also don't warn on the last frame with fixed block size blocking strategy
that the block size has changed: the last frame is allowed to be smaller.

dbbfc917fe flacparse: Avoid integer overflow in available data check for image tags
If the image length as stored in the file is some bogus integer then
adding it to the current byte readers position can overflow and wrongly
have the check for enough available data succeed.

This then later can cause NULL pointer dereferences or out of bounds
reads/writes when actually reading the image data.
