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.

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.

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.

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.

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.

It's not really a shallow copy. It just doesn't cross indirect object
