Bug fix: properly handle overridden compressed objects
...
When caching objects in an object stream, only cache objects that
still resolve to that stream. See Changelog mod from this commit for
details.

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.

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.

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.

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.

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.
