Avoid buffer overrun copying digest
...
Converting a password to an encryption key is supposed to copy up to a
certain number of bytes from a digest. Make sure never to copy more
than the size of the digest.

Security: replace operator[] with at

For std::string and std::vector, replace operator[] with at. This was
done using an automated process. See README.hardening for details.

Handle more broken files
...
Space rather than newline after xref, missing /ID in trailer for
encrypted file. This enables qpdf to handle some files that xpdf can
handle. Adobe reader can't necessarily handle them.

Support for encryption with /V=5 and /R=5 and /R=6
...
Read and write support is implemented for /V=5 with /R=5 as well as
/R=6. /R=5 is the deprecated encryption method used by Acrobat IX.
/R=6 is the encryption method used by PDF 2.0 from ISO 32000-2.

Add command line option to copy encryption from other file
...
Add --copy-encryption and --encryption-file-password options to qpdf.
Also strengthen test suite for copying encryption. The strengthened
test suite would have caught the failure to preserve AES and the
failure to update the file version, which was invalidating the
encrypted data.

ABI change: fix use of off_t, size_t, and integer types
...
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.

Implement changes suggested by Zarko and our subsequent conversations:
...
- Add a way to set the minimum PDF version
- Add a way to force the PDF version
- Have isEncrypted return true if an /Encrypt dictionary exists even
when we can't read the file
- Allow qpdf_init_write to be called multiple times
- Update some comments in headers

Fix libtests test suites to pass on Windows, mostly by dealing with
