b1dad0de2a Fix previous fix to setting checkbox value (fixes #1056)
The code accepted values other than /Yes but still used /Yes as the
checked value instead of obeying the normal appearance dictionary.

...as well as some cases generated in CI from earlier attempts at
fixing this.

cb0f390cc1 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.

6e3b7982db 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.

because, in both cases, `file` was alphabetically before the other
keys, but this implementation gives a stronger guarantee.
