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.

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.

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

- 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
ascii vs. binary and NL vs. CRNL change ($td->NORMALIZE_NEWLINES).
Convert some test suites to use fread instead of read.
PCRE.hh: define PCRE_STATIC if on Windows.
Provide cross-platform function for getting current time instead of
using time(0).
