164cbdde46 Protect against virus warnings (fixes #216) 
Some files in the test suite trigger antivirus warnings. These are
not infected files with malicious intent. They are test files to
ensure that qpdf does not crash when it encounters the files. This
change enables those files to be obfuscated in the source repository
so that checking out qpdf from version control or extracting the
source code doesn't trigger antivirus warnings.

3d6615b276 Pl_Buffer: reduce memory growth (fixes #228) 
Rather than keeping a list of buffers for every write, accumulate
bytes in a single buffer, doubling the size of the buffer when needed
to accommodate new data.

This is not the best possible implementation, but the change was
implemented in this way to avoid changing the shape of Pl_Buffer and
thus breaking backward compatibility.

932799baab Fix memory access error 
A previous fix introduced a potentially memory overrun under certain
rare conditions. The test suite now once again passes with address
sanitizer.

b6e414b10b Remove some extraneous null pointer checks (fixes #234) 
There were a few places in the code that were checking that a pointer
wasn't null before deleting it, even though C++ has always allowed
delete 0. Most of the code did not perform these checks.

4a4736c695 Fix EOL handling inside strings (fixes #226)

to be ignored after backslash.

e1cd5891af Fix infinite loop on small files with progress reporting (fixes #230) 
Turns out you can keep adding zero to a number over and over again and
it just doesn't get any bigger. Who would have known?

c71dc6888c Don't prune resource dictionaries on errors or by request 
If we are unable to filter a page's content streams, don't attempt to
remove objects from the page's resource dictionary. Also provide a
command line option to suppress resource removal in case we ever need
this as a workaround for some bug or broken PDF files.

38c9ed23c3 Treat content stream parsing errors as an error, not a warning 
If parsing content streams is treated as a warning, there is no way
for a caller to know if a parsing operation has failed. This is very
dangerous and will likely result in data loss when token filters are
parser callbacks are in use.
