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.

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.

041397fdab Allow reading from InputSource and writing to Pipeline 
Allowing users to subclass InputSource and Pipeline to read and write
from/to arbitrary sources provides the maximum flexibility for users
who want to read and write from other than files or memory.

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.

8a217eb3a2 Add concept of reserved objects 
QPDFObjectHandle::{new,is,assert}Reserved, QPDF::replaceReserved
provide a mechanism to add objects to a PDF file when there are
circular references.  This is a prerequisite to copying objects from
one PDF to another.

81e8752362 Use qpdf_offset_t in place of off_t in public APIs. 
off_t is used internally only when needed to talk to standard
libraries.  This requires that the "long long" type be supported by
the compiler.

5d4cad9c02 ABI change: fix use of off_t, size_t, and integer types 
Significantly improve the code's use of off_t for file offsets, size_t
for memory sizes, and integer types in cases where there has to be
compatibility with external interfaces.  Rework sections of the code
that would have prevented qpdf from working on files larger than 2 (or
maybe 4) GB in size.
