4e8d21d849 Build Windows releases with openssl; automate external libraries 
External libraries for Windows are now built automatically in the
qpdf/external-libs repository and include openssl in addition to zlib
and jpeg. Use these, and update the Windows build to build with the
openssl crypto provider by default. We leave the native crypto
provider enabled in case there is a problem with openssl and also to
continue to exercise that code.

956c8f6432 Obscure bug fix copying foreign streams in special cases (fixes #449) 
Specifically, if a stream had its stream data replaced and had
indirect /Filter or /DecodeParms, it would result in non-silent loss
of data and/or internal error.

ef127001b3 Remove some fuzz files with Mal/PDFEx-H (fixes #460) 
There isn't really an issue with these files causing a real problem,
but malware and virus checkers trip on them, and the value to leaving
them in the test suite is too low to be worth the hassle.

whether wmain is in use.

658b5bb3be QPDFWriter: clean up overloaded functions 
In a small number of cases, it makes sense to replace an overloaded
function with a function that takes a default argument. We can do this
now because we've already broken binary compatibility since the last
release.

79f6b4823b Convert remaining public classes to use Members pattern 
Have classes contain only a single private member of type
PointerHolder<Members>. This makes it safe to change the structure of
the Members class without breaking binary compatibility. Many of the
classes already follow this pattern quite successfully. This brings in
the rest of the class that are part of the public API.

a5a016cdd2 Revert preservations of outlines with --split-pages 
The preservation of outlines didn't provide very useful behavior
anyway as it copied all outlines but most didn't work. This
implementation also caused a very significant performance hit and so
is being reverted until a proper solution can be coded. The eventual
solution will not be compatible with the reverted solution anyway, so
it's best not to leave this in.
