Log Message:
qpdf: Update to 11.6.3

Changelog:
11.6.3: October 15, 2023

        Bug fixes:

            Fix a bug in which qpdf could potentially discard a character in a \ 
binary string if that character was preceded by an octal escaped string with \ 
fewer than three digits. This bug was introduced in the 11.0.0 release. The bug \ 
would not apply to content streams with default settings.

            The linearization specification precludes linearized files that \ 
require offets past the 4 GB mark. A bug in qpdf was preventing it from working \ 
when offsets had to pass the 2 GB mark. This has been corrected.

11.6.2: October 7, 2023

        Bug fixes:

            Fix a very old bug that could cause qpdf to call an internal finish \ 
function twice on certain stream decoding errors. With certain incorrect input \ 
files, this could cause qpdf to call gnutls or openssl 1 in a way that could \ 
cause them to crash.

        Development changes:

            Control some .idea files for JetBrains CLion. We will be iterating \ 
on making it easier to work with qpdf in CLion in coming releases.
