d71f05ca07 Fix sign and conversion warnings (major) 
This makes all integer type conversions that have potential data loss
explicit with calls that do range checks and raise an exception. After
this commit, qpdf builds with no warnings when -Wsign-conversion
-Wconversion is used with gcc or clang or when -W3 -Wd4800 is used
with MSVC. This significantly reduces the likelihood of potential
crashes from bogus integer values.

There are some parts of the code that take int when they should take
size_t or an offset. Such places would make qpdf not support files
with more than 2^31 of something that usually wouldn't be so large. In
the event that such a file shows up and is valid, at least qpdf would
raise an error in the right spot so the issue could be legitimately
addressed rather than failing in some weird way because of a silent
overflow condition.

found. This commit just refactors the code without changing the
functionality and adds tests to make sure the old and new code behave
identically.

this is still a significant improvement.

a01359189b Fix dangling references (fixes #240) 
On certain operations, such as iterating through all objects and
adding new indirect objects, walk through the entire object structure
and explicitly resolve any indirect references to non-existent
objects. That prevents new objects from springing into existence and
causing the previously dangling references to point to them.

f78ea057ca Switch annotation flattening to use the form xobjects 
Instead of directly putting the contents of the annotation appearance
streams into the page's content stream, add commands to render the
form xobjects directly. This is a more robust way to do it than the
original solution as it works properly with patterns and avoids
problems with resource name clashes between the pages and the form
xobjects.

3440ea7d3c JSON::serialize -> unparse

comes from the "clu" programming language.)

a11549a566 Detect loops in /Pages structure 
Pushing inherited objects to pages and getting all pages were both
prone to stack overflow infinite loops if there were loops in the
Pages dictionary. There is a general weakness in the code in that any
part of the code that traverses the Pages structure would be prone to
this and would have to implement its own loop detection. A more robust
fix may provide some general method for handling the Pages structure,
but it's probably not worth doing.

Note: addition of *Internal2 private functions was done rather than
changing signatures of existing methods to avoid breaking
compatibility.

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.

43c404b45a Add QPDFObjectHandle::newStream(QPDF *, std::string const&) 
This makes the code simpler than having to create a buffer of a fixed
size and copy the string to it.

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

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.

b856379370 Portability issues: off_t, unlink

defined on any platform and in a way that would work with large file
support.  Additionally, missing header files are included to get
unlink.

Fix libtests test suites to pass on Windows, mostly by dealing with
ascii vs. binary and NL vs. CRNL change ($td->NORMALIZE_NEWLINES).
Convert some test suites to use fread instead of read.
PCRE.hh: define PCRE_STATIC if on Windows.

using time(0).
