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.

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.

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)

25988e8d10 Bug fix: content normalizer should not add trailing newline
Adding a trailing newline in content normalization damages files whose
contents are split across streams in the middle of tokens. Let
QPDFWriter add the newline with the indicator to ignore the newline,
which it already does. This changes the way some qdf files look.

ae0399ef87 Revert "Add page rotation example in contrib"
This reverts commit 8ee83ca722.

This is being removed because qpdf now has its own page rotation. The
example was an excellent contribution to qpdf, but now it illustrates
rotating pages "by hand", which is no longer needed because of
QPDFObjectHandle::rotatePage.
