62bf296a9c Make assert handling less error-prone 
Prevent my future self or other contributors from using assert in
tests and then having that assert not do anything because of the
NDEBUG macro.

c365a26e9d Revert "Remove QPDFObjectHandle::replaceOrRemoveKey" 
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. :-)

5bbb0d4c30 Replace switch statements with static map initializers 
Character transcoding from Unicode to single-byte characters used
hard-coded switch statements because the code predated our adoption of
C++11. Now we have thread-safe, static initialization of map literals,
so use that instead.

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.

Add comments to force line breaks, parenthesize function arguments
that are contatenated strings, etc. -- these kinds of changes improve
clang-format's results and also cause emacs cc-mode to match
clang-format. After this type of change, most of the time, when
clang-format and emacs disagree, clang-format is better.

1065bbb016 Handle odd PDFDoc codepoints in UTF-8 during transcoding (fixes #650) 
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.

c62ab2ee9f QPDFJob: use pointers instead of references for Config

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.

appropriate division between qpdf.cc and QPDFJob.

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

They have to be ot_* rather than qpdf_ot_* for compatibility.

* Different enumerated types are not assignment-compatible in C++, at

* 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.

f45dacf4cb Make recovery logic flexible about where objects end (fixes #573) 
Don't assume endobj is at the beginning of the line. This means we are
looking at tokens for every line, but the odds of n n obj appearing in
the middle of the object are likely much lower than endobj not being
at the beginning of the line or missing entirely. This will probably
have a negative impact on recovery time for very large files.
Hopefully it will be worth it.

96767fb104 Fix foreign stream copying bug (fixes #478) 
This reverts an incorrect fix to #449 and codes it properly. The real
problem was that we were looking at the local dictionaries rather than
the foreign dictionaries when saving the foreign stream data. In the
case of direct objects, these happened to be the same, but in the case
of indirect objects, the object references could be pointing anywhere
since object numbers don't match up between the old and new files.

9a3791c53b Properly detect OPENSSL_IS_BORINGSSL 
OPENSSL_IS_BORINGSSL is not actually set by configure, so it will be
undefined until a BoringSSL header is included.  Hence the #ifdef logic
in QPDFCrypto_openssl.h would usually never apply.

This still worked because evp.h transitively included BoringSSL's
cipher.h and digest.h, but the latter are the correct (documented)
headers.

By re-ordering the includes, we can ensure the macro is defined when we
use it.

Also: fix case in the header guards.
