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 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.
