This uses C++-11 thread-safe static initializers now.
-
This was being saved until we had to break ABI.
-
This commit adds the preserve_eol flags but doesn't implement EOL preservation yet.
-
Use PointerHolder in several places where manually memory allocation and deallocation were being used. This helps to protect against memory leaks when exceptions are thrown in surprising places.
-
This code was essentially duplicated between test_driver and standalone_fuzz_target_runner.

This makes all integer type conversions that have potential data loss explicit with calls that do range checks and raise an exception. After this commit, qpdf builds with no warnings when -Wsign-conversion -Wconversion is used with gcc or clang or when -W3 -Wd4800 is used with MSVC. This significantly reduces the likelihood of potential crashes from bogus integer values. There are some parts of the code that take int when they should take size_t or an offset. Such places would make qpdf not support files with more than 2^31 of something that usually wouldn't be so large. In the event that such a file shows up and is valid, at least qpdf would raise an error in the right spot so the issue could be legitimately addressed rather than failing in some weird way because of a silent overflow condition.

…lassic one nor newer ones based on CLANG.

If set, we avoid using Windows I/O HANDLE, which is disallowed in some versions of the Windows SDK, such as for Windows phones. QUtil::same_file will always return false in this case. Only applies to Windows builds.

Also move tests to libtests.

Use 0 instead of NULL in a cast.
