0873e42300 SHA2 pipeline with support for 256, 384, and 512 bits 
Implemented pipeline around sph sha calls using standard test vectors
for full-byte values.  Did not test or support partial byte values.

c9da66a018 Incorporate sha2 code from sphlib 3.0 
Changes from upstream are limited to change #include paths so that I
can place header files and included "c" files in a subdirectory.  I
didn't keep the unit tests from sphlib but instead verified them by
running them manually.  I will implement the same tests using the
Pl_SHA2 pipeline except that sphlib's sha2 implementation supports
partial bytes, which I will not exercise in qpdf or our tests.

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.

b26ce88ea1 Minor fixes to copyEncryptionParameters 
This fixes were to code added yesterday; the problems would not have
impacted any previously released code.  These are all changes related
to the possibility that copyEncryptionParameters may be called on
behalf a different QPDF than the one being written.

8a217eb3a2 Add concept of reserved objects 
QPDFObjectHandle::{new,is,assert}Reserved, QPDF::replaceReserved

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

e2dedde4bd Don't require stream data provider to know length in advance 
Breaking API change: length parameter has disappeared from the
StreamDataProvider version of QPDFObjectHandle::replaceStreamData
since it is no longer necessary to compute it in advance.  This
breaking change is justified by the fact that removing the length
parameter provides the caller an opportunity to simplify the calling
code.

abb53ac369 Limited inheritance to the attributes explicitly listed in the PDF spec 
Previous versions of qpdf incorrectly passed arbitrary objects from
/Pages objects down to individual pages in direct contradition with
the PDF specification.  These are now left in /Pages.  When
intermediate /Pages nodes are being discarded as when the /Pages tree
is being flattened, a warning is issued when unknown keys are
encountered.

Significantly improve the code's use of off_t for file offsets, size_t

compatibility with external interfaces.  Rework sections of the code
that would have prevented qpdf from working on files larger than 2 (or
