Handle parse error stream data ( fixes #1123 )
...
A parse error in stream data in which stream data contained a nested
object would cause a crash because qpdf was not correctly updating its
internal state. Rework the QPDF json reactor to not be sensitive to
parse errors in this way.

Fix incorrect handling of invalid negative object ids

Fix two errors introduced in #1110 and #1112 . Since
#1110 , encountering the invalid indirect reference #1110
-2147483648 n R produces an integer underflow which, if
undetected, immediately trigger a logic error. Since
#1112 , object -1 0 R may be incorrectly identified as
an earlier generation of itself and deleted,
invalidating a live iterator.
