fix crash in QXmlStreamReader

this fixes a possible off-by-one data corruption which apparently is
only triggered in rare circumstances.

The problem was: We were checking whether we would need to reallocate
the stack (line 1245), but sometimes were incrementing tos (line 1278)
and then accessing the state stack at an out-of-bounds position (line
1951).

Additionally, adapt the qlalr generator for changes made to
qxmlstream_p.h directly and recreate that file with qlalr.
