Replace some assertions with std::logic_error
...
Ideally, the library should never call assert outside of test code,
but it does in several places. For some cases where the assertion
might conceivably fail because of a problem with the input data,
replace assertions with exceptions so that they can be trapped by the
calling application. This commit surely misses some cases and
replaced some cases unnecessarily, but it should still be an
improvement.

Change API/ABI and withdraw 4.2.0
...
4.2.0 was binary incompatible in spite of there being no deletions or
changes to any public methods. As such, we have to bump the ABI and
are fixing some API breakage while we're at it.
Previous 4.3.0 target is now 5.1.0.

Bug fix: handle generation > 0 when generating object streams
...
Rework QPDFWriter to always track old object IDs and QPDFObjGen
instead of int, thus not discarding the generation number. Switch to
QPDF::getCompressibleObjGen() to properly handle the case of an old
object eligible for compression that has a generation of other than
zero.

Mark secure CRT warnings with comment
...
Put a specific comment marker next to every piece of code that MSVC
gives warning 4996 for. This warning is generated for calls to
functions that Microsoft considers insecure or deprecated. This
change is in preparation for fixing all these cases even though none
of them are actually incorrect or insecure as used in qpdf. The
comment marker makes them easier to find so they can be fixed in
subsequent commits.

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.
