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.

4f8c734d8e Missing free in some test code
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.

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.

e0d1cd1f4b Fix test case
There was an unintended recoverable error in a test file. It wasn't
hurting anything, but it was obscuring the actual intent of the test.

this is handled as a special case.

ef8ae5449d Allow QPDFTokenizer::readToken to return bad tokens
Sometimes we want to ignore bad tokens rather than having them throw
an exception. A coverage case is commented out here and added in a
later commit.
