1868a10f8b Replace all atoi calls with QUtil::string_to_int
The latter catches underflow/overflow.

abb3191c32 Add tests for previous memory issues
Now that the test suite runs clean with address sanitizer, add some
test cases that previously were used to expose memory errors.

There was a missing free causing a memory leak in some test code. The

fabff0f3ec Limit token length during xref recovery
While scanning the file looking for objects, limit the length of
tokens we allow. This prevents us from getting caught up in reading a
file character by character while digging through large streams.

f08ce00e62 Add tests for PCLm
Files written in PCLm mode have to be created in a very specific way.
qpdf doesn't know how to create PCLm files from scratch. All it knows
how to do is to write an already valid file in a suitable way.
Therefore there is no command-line support for PCLm.

389396dbbf Support Windows builds with MSYS2
Replace the old msys, mingw-w64, ActiveState perl setup with MSYS2.
This greatly simplifies the Windows build. This was facilitated by the
need to incorporate JPEG.

ddc6cf0cf6 Precheck streams by default
There is no need for a --precheck-streams option. We can do the
precheck without imposing any penalty, only re-encoding the stream if
it fails the first time.

9744414c66 Enable finer grained control of stream decoding
This commit adds several API methods that enable control over which
types of filters QPDF will attempt to decode. It also adds support for
/RunLengthDecode and /DCTDecode filters for both encoding and
decoding.
