Refactoring the big image format switch in ContinueDecode to call

By catching this early we are now actually returning the wrong
value. The bad value should be passed into the jpeg library code,
which will cause a fatal error and jump out to the common error
handling code for this method.

This moves the setjmps needed for handling fatal errors in the jpeg
library up a level to be in line with how other instances of this are
being modified. This additionally reduces the number of times that
setjmp needs to be called and documents why it is occurring.
This covers the Start and ReadScanLine methods. It also adds in
setting the error member, which had been missed in previous CLs.

This functional part of this CL is mostly a revert of
"Change behaviour of FPDF_RenderPageBitmapWithMatrix"
24b0733a72bbc4013bff8628f198b0aea807aa06
Besides the revert, the parameters passed to
pPage->GetDisplayMatrix() are changed to fix a bug with the previous
implementation: the page was scaled to fit inside the clipping_rect,
instead of clipped.

The current implementation treats both returning false and longjmp'ing
out of jpeg_start_decompress as indicating that the decompression has
paused and needs more data. This is incorrect, in reality only the
false return value indicates this. The longjmp path indicates a fatal
error in the processing of the jpeg. The default implementation
actually calls exit() in this case, and the documentation explicitly
calls out that in this case recovery isn't possible and the decode
process will have to start from scratch.
This resolves a situation where the progressive decoder would get a
malformed jpeg and keep on grabbing blocks from it and try to start
decoding it. This would eventually fail when it ran out of data to
read, but would cause a large memory leak and a crash on the MSAN
fuzzers.
