xdvipdfmx problems after update from version 20190225 to 20190503

[Shunsaku Hirata]

Hi Jens,

The problem occurs when dvipdfmx tries to zlib decompress data.

I observed similar error when extracting data from provided file by
qpdf program,

$ qpdf --filtered-stream-data --show-object=4 Spectrum-pdfreport.pdf
WARNING: Spectrum-pdfreport.pdf (file position 179): error decoding
stream data for object 4 0: stream inflate: inflate: data: incorrect
data check
stream inflate: inflate: data: incorrect data check

suggesting corrupted data.
I also checked error code and message returned by inflate() and found
the same error.

I think there must be some recoverable (since Acrobat, Ghostscript,
and many other PDF viewers can process it) error in
compressed data but I don't know the exact reason.

The reason why previous versions of dvipdfmx can process it is that
they do not decompress data in some cases.

I will consider workaround for this issue but it may take some time.
Also for FontAwesome TrueType font problem I will inspect it later.

Thanks,
Shunsaku Hirata
