6f43bf8de3 Major rework -- see long comments 
* Replace --create-from-json=file with --json-input, which causes the
  regular input to be treated as json.
* Eliminate --to-json
* In --json=2, bring back "objects" and eliminate "objectinfo". Stream
  data is never present.
* In --json-output=2, write "qpdf-v2" with "objects" and include
  stream data.

051ae7c282 Improve handling of replacing stream data with empty strings 
When an empty string was passed to replaceStreamData, the code was
passing a null pointer to memcpy. Since a 0 size was also passed, this
was harmless, but it triggers sanitizer errors. The code properly
handles a null pointer as the buffer in other places.

This reverts commit dc059560e7.

I changed my mind. There's no harm in leaving it deprecated for a
release cycle.

4f24617e1e Code clean up: use range-style for loops wherever possible 
Where not possible, use "auto" to get the iterator type.

Editorial note: I have avoid this change for a long time because of
not wanting to make gratuitous changes to version history, which can
obscure when certain changes were made, but with having recently
touched every single file to apply automatic code formatting and with
making several broad changes to the API, I decided it was time to take
the plunge and get rid of the older (pre-C++11) verbose iterator
syntax. The new code is just easier to read and understand, and in
many cases, it will be more effecient as fewer temporary copies are
being made.

m-holger, if you're reading, you can see that I've finally come
around. :-)

07edf96440 Remove methods of private classes from ABI 
Prior to the cmake conversion, several private classes had methods
that were exported into the shared library so they could be tested
with libtests. With cmake, we build libtests using an object library,
so this is no longer necessary. The methods that are disappearing from
the ABI were never exposed through public headers, so no code should
be using them. Removal had to wait until the window for ABI-breaking
changes was open.

There are codepoints in PDFDoc that are not valid UTF-8 but map to
valid UTF-8. We were handling those correctly with bidirectional
mapping.

However, if those same code points appeared in UTF-8, where they have
no meaning, they were left as fixed points when converting to PDFDoc,
where they do have meaning. This change recognizes them as errors.

cb769c62e5 WHITESPACE ONLY -- expand tabs in source code 
This comment expands all tabs using an 8-character tab-width. You
should ignore this commit when using git blame or use git blame -w.

In the early days, I used to use tabs where possible for indentation,
since emacs did this automatically. In recent years, I have switched
to only using spaces, which means qpdf source code has been a mixture
of spaces and tabs. I have avoided cleaning this up because of not
wanting gratuitous whitespaces change to cloud the output of git
blame, but I changed my mind after discussing with users who view qpdf
source code in editors/IDEs that have other tab widths by default and
in light of the fact that I am planning to start applying automatic
code formatting soon.

If some keys depend on others, we have to check up front since there
is no control of what order key handlers will be called. Anyway, keys
are unordered in json, so we don't want to depend on ordering.

Since the functionality of argument parsing has moved into QPDFJob,
these classes no longer need to be public. Their methods still have to
be in the library's binary interface so they can be tested in libtests.

c62ab2ee9f QPDFJob: use pointers instead of references for Config 
Why? The main methods that create them return smart pointers so that
users can initialize them when needed, which you can't do with
references. Returning pointers instead of references makes for a more

67f9d0b7d5 cli.rst: remove () from end of short help 
This is used to generate a schema for the job json, which can't
contain `)"` because it breaks the R"(...)" syntax in C++. While C++
accepts R"anything(...)anything" to avoid this, as of this writing,
MSVC 2019 doesn't understand that. For now, just avoid it by removing
parentheses from the end of short help.

There are temporary bits of code to enable everything to compile and
pass the test suite, including some duplication and hard-coded values.

* While you can do `constexpr ot_xyz = ::qpdf_ot_xyz` in QPDFObject.hh to
  make QPDFObject::ot_xyz work, QPDFObject::object_type_e::ot_xyz will
  only work if the enumerated type names are the same.

have a negative impact on recovery time for very large files.

9b28933647 Check object ownership when adding 
When adding a QPDFObjectHandle to an array or dictionary, if possible,
check if the new object belongs to the same QPDF. This makes it much
easier to find incorrect code than waiting for the situation to be
detected when the file is written.

33a47d5c3c Make QPDF::findPage public (fixes #516) 
This was originally not public because I wanted to get rid fo the
pages cache, but I recently realized there were deep reasons not to do
that, and the author of pikepdf wanted this, so I decided to make it
public.
