Fix a bug loading some compressed files

For https://bugzilla.gnome.org/show_bug.cgi?id=712528
Related to https://bugzilla.redhat.com/show_bug.cgi?id=877567

There is a bug in xzlib.c which causes certain compressed XML files to fail to
load correctly.  The code in xz_decomp which attempts to verify the checksum
and length of the expanded data fails if the checksum or length at the end of
the file crosses a 1024 byte boundary.  It calls gz_next4 to get those two
values.  This function uses the stream state in state->zstrm, but calls
xz_avail which uses the state->strm stream info.  This causes gz_next4 to
signal a premature EOF if the data it is fetching crosses a 1024 byte boundary.
