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.

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.

e4e2e26d99 Properly handle pages with no contents (fixes #194) 
Remove calls to assertPageObject(). All cases in the library that
called assertPageObject() work fine if you don't call
assertPageObject() because nothing assumes anything that was being
checked by that call. Removing the calls enables more files to be
successfully processed.

ee44aef8d0 Treat loop in xref tables as damage (fixes #192) 
Prior to this fix, if there was a loop detected in following /Prev
pointers in xref streams/tables, it would cause qpdf to lose data.
Note that this condition causes many PDF readers to hang or fail.

4bb3046f0b Properly handle strings with PDF Doc Encoding (fixes #179) 
The QPDF_String::getUTF8Val() method was not treating strings that
weren't explicitly Unicode as PDF Doc Encoded. This only affects
characters in the range 0x80 through 0xa0.

d0e99f195a More robust handling of type errors 
Give objects descriptions and context so it is possible to issue
warnings instead of fatal errors for attempts to access objects of the
wrong type.
