Reimplement name and number tree object helpers
...
Create a computationally and memory efficient implementation of name
and number trees that does binary searches as intended by the data
structure rather than loading into a map, which can use a great deal
of memory and can be very slow.

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.

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.
