cee2592ed1 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.

a85007cb0d Handle more broken files 
Space rather than newline after xref, missing /ID in trailer for
encrypted file.  This enables qpdf to handle some files that xpdf can
handle.  Adobe reader can't necessarily handle them.

16051788ed Handle /Outlines dictionary being a direct object 
Even though this case is not valid according to the spec, it has been
seen, and caused an internal error.

a3576a7359 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.

5039da0b91 Add QPDFObjectHandle::getObjGen()

fd64959398 Favor strerror_s and fopen_s on MSVC

on MSVC.

ac4deac187 Call QUtil::safe_fopen in place of fopen 
fopen was previuosly called wrapped by QUtil::fopen_wrapper, but
QUtil::safe_fopen does this itself, which is less cumbersome.

a11081085b Handle warning flags better 
Make --enable-werror work properly on msvc, handle extra warnings
flags for msvc in configure.ac instead of hardcoding into
make/msvc.mk, separate warnings flags into WFLAGS in autoconf.mk to
avoid duplication and to make it easier to override.

and use it in place of sprintf where possible.

6c7bf114dc 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.

7e7c93951f Do not remove libqpdf.la 
Some distributions (like debian) don't want .la files to be installed,
but the responsibility for doing this should like in the packaging,
not in qpdf itself.

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.
