a85007cb0d Handle more broken files 
Space rather than newline after xref, missing /ID in trailer for
encrypted file.  This enables qpdf to handle some files that xpdf can
handle.  Adobe reader can't necessarily handle them.

16051788ed Handle /Outlines dictionary being a direct object 
Even though this case is not valid according to the spec, it has been
seen, and caused an internal error.

a3576a7359 Bug fix: handle generation > 0 when generating object streams 
Rework QPDFWriter to always track old object IDs and QPDFObjGen
instead of int, thus not discarding the generation number.  Switch to
QPDF::getCompressibleObjGen() to properly handle the case of an old
object eligible for compression that has a generation of other than
zero.

6c7bf114dc Bug fix: properly handle overridden compressed objects 
When caching objects in an object stream, only cache objects that
still resolve to that stream.  See Changelog mod from this commit for
details.

errors when possible, add test case for parsing a file with content
stream errors on some but not all pages.

4237a29c94 Refactor Dictionary writing code 
Original code was written before we could shallow copy objects, so all
the filtering was done by suppressing the output of certain keys and
replacing them with other keys.  Now we can simplify the code greatly
by modifying shallow copies of dictionaries in place.

e57c25814e Support for encryption with /V=5 and /R=5 and /R=6 
Read and write support is implemented for /V=5 with /R=5 as well as
/R=6.  /R=5 is the deprecated encryption method used by Acrobat IX.
/R=6 is the encryption method used by PDF 2.0 from ISO 32000-2.

35873031a7 Uncompress stream data for some linearization tests 
For linearization tests where we are actually comparing the exact
output of the test with a known file, uncompress stream data so we can
see what's there.  This makes looking at future changes a little
easier.

6bbea4baa0 Implement QPDFObjectHandle::parse 
Move object parsing code from QPDF to QPDFObjectHandle and
parameterize the parts of it that are specific to a QPDF object.
Provide a version that can't handle indirect objects and that can be
called on an arbitrary string.

A side effect of this change is that the offset used when reporting
invalid stream length has changed, but since the new value seems like
a better value than the old one, the test suite has been updated
rather than making the code backward compatible.  This only effects
the offset reported for invalid streams that lack /Length or have an
invalid /Length key.

Updated some test code and exmaples to use QPDFObjectHandle::parse.

Supporting changes include adding a BufferInputSource constructor that
takes a string.

a101533e0a Add command line option to copy encryption from other file 
Add --copy-encryption and --encryption-file-password options to qpdf.
Also strengthen test suite for copying encryption.  The strengthened
test suite would have caught the failure to preserve AES and the
failure to update the file version, which was invalidating the
encrypted data.

8a217eb3a2 Add concept of reserved objects

circular references.  This is a prerequisite to copying objects from
one PDF to another.
