bfda717749 Cosmetic changes to be closer to Adobe terminology
Change object type Keyword to Operator, and place the order of the
object types in object_type_e in the same order as they are mentioned
in the PDF specification.

Note that this change only breaks backward compatibility with code
that has not yet been released.

9261f3b922 Detect binary attachments better
This fix eliminates a false test failure on some platforms and makes
the binary test work properly whether characters with the high bit
set, when treated as integers, are negative or not.

0ea70e5dae Update shared library major version to 10
The upcoming 3.1 release contains non-compatible API changes, though
they only affect parts of the interface that are extremely unlikely to
have been used outside of qpdf itself.  The methods and data types
affected were used for communication between QPDFWriter and QPDF and
would have had no real use in end user code.

9a23c3dcb6 Remove /Crypt from stream filters unconditionally
When writing a new stream, always remove /Crypt even if we are not
otherwise able to filter the stream.

4237a29c94 Refactor Dictionary writing code
Original code was written before we could shallow copy objects, so all
the filtering was done by suppressing the output of certain keys and
replacing them with other keys.  Now we can simplify the code greatly
by modifying shallow copies of dictionaries in place.

e57c25814e 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.

0873e42300 SHA2 pipeline with support for 256, 384, and 512 bits
Implemented pipeline around sph sha calls using standard test vectors
for full-byte values.  Did not test or support partial byte values.

c9da66a018 Incorporate sha2 code from sphlib 3.0
Changes from upstream are limited to change #include paths so that I
can place header files and included "c" files in a subdirectory.  I
didn't keep the unit tests from sphlib but instead verified them by
running them manually.  I will implement the same tests using the
Pl_SHA2 pipeline except that sphlib's sha2 implementation supports
partial bytes, which I will not exercise in qpdf or our tests.

b4b8b28ed2 Reference object with zero offset
This file used to exercise a zero offset test case when qpdf would
visit every object in the file.  After the next commit, qpdf no longer
touches unreferenced objects, so a reference had to be added to
continue to have this file exercise the zero offset case.

35873031a7 Uncompress stream data for some linearization tests
For linearization tests where we are actually comparing the exact
output of the test with a known file, uncompress stream data so we can
see what's there.  This makes looking at future changes a little
easier.
