OpenSystemsDevelopment / qpdf

Added methods to append to arrays, insert items into arrays, and
replace array contents with a vector of items.

Significantly improve the code's use of off_t for file offsets, size_t
for memory sizes, and integer types in cases where there has to be
compatibility with external interfaces.  Rework sections of the code
that would have prevented qpdf from working on files larger than 2 (or
maybe 4) GB in size.

For ELF systems, turn on versioned symbols by default, and add a
configure option to enable or disable them.

pcre_info -> pcre_fullinfo.  Closes issue 3489349.  Thanks Tim Harder.

…would probably never manifest itself without other code changes

… of delete, thus making it useful to run valgrind over qpdf during its test suite
