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.

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.

ddd78c1b7f Fix QPDFObjectHandle::shallowCopy 
It's not really a shallow copy. It just doesn't cross indirect object
boundaries. The old implementation had a bug that would cause multiple
shallow copies of the same object to share memory, which was not the
intention.

15ed9f8565 Fix small logic error in Token construct (fixes #206) 
The special case around name token was not reachable. This would only
affect constructors of name tokens that were represented in
non-canonical form such as with a hex substitution for a printable
character. The error was harmless but still a bug.
