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.

56f1b411fe Back out fluent QPDFObjectHandle methods. Keep the andGet methods. 
I decided these were confusing and inconsistent with how JSON works.
They muddle the API rather than improving it.

c365a26e9d Revert "Remove QPDFObjectHandle::replaceOrRemoveKey" 
This reverts commit dc059560e7.

90cfe80bac Clean up/fix DLL.h 
* Change DLL_EXPORT to libqpdf_EXPORTS (internal to the build). The
  new name is cmake's default, is more conventional, and is less
  likely to clash with other symbols.
* Add QPDF_DLL_PRIVATE for non-Windows
* Make logic around when to define QPDF_DLL et al more explicit
* Add detailed comments

acc24ba494 Only install docs if they exist 
Sometimes someone may build only a subset of the documentation. The
logic has to be conditional upon whether it exists, not whether it is
built, since we pull pre-built docs in for CI installation.

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.

At one time, it seems that I was starting to use the <firstterm>
feature of docbook, but I forgot about it long ago, and there is
nothing consistent. In the absence of an actual glossary, just use
emphasis for terminology and don't tag it in any special way. This
could be fixed later if we wanted to.

@3@replaceable@3@...@3@replaceable@3@ inside of :samp: and :file: so
that all remaining @1@replaceable@1@...@2@replaceable@2@ are outside.
Since the {...} syntax for replaceable only works in :samp: and
:file:, we will have to enclose the remaining ones in :samp: for them
to work.

Replace @1@...@2@ stuff from prior to the conversion with new
representation.

cf3b9a7783 doc: fix whitespace and indentation in pandoc output 
Pandoc indented lists with two spaces after the dash, which is ugly
and messes up emacs fill-paragraph. I transformed the spacing using a
combination of this perl script and manual edits. I verified that the
HTML generated by sphinx was identical before and after the edits and
that this commit contains only whitespace changes. The perl script as
it stands does not do indentation quite right for variable lists, but
there were only about 8 cases that it missed, so I just fixed them
manually.

```perl
#!/usr/bin/env perl
require 5.008;
use warnings;
use strict;
use File::Basename;

my $whoami = basename($0);

my @liststack = ();

while (<>)
{
    if (m/^( *-  )\S/)
    {
        my $pre = $1;
        while ((scalar(@liststack) > 0) &&
               ($liststack[-1] >= length($pre)))
        {
            pop(@liststack);
        }
        if ((scalar(@liststack) == 0) && ($pre =~ m/^ /))
        {
            push(@liststack, 1);
        }
        push(@liststack, length($pre));
        my $n = scalar(@liststack);
        #print "** $n\n";
        my $newpre = ('  ' x ($n - 1)) . '- ';
        s/^$pre/$newpre/;
    }
    elsif (scalar(@liststack) > 0)
    {
        if ($_ ne "\n")
        {
            while (scalar(@liststack) > 0)
            {
                my $pre = m/^( *)/;
                if (length($1) < $liststack[-1])
                {
                    #print "XXX pop\n";
                    pop(@liststack);
                }
                else
                {
                    last;
                }
            }
            my $n = scalar(@liststack);
            #print "** $n\n";
            my $indent = '  ' x $n;
            s/^ +/$indent/;
        }
    }
    print;
}

Also remove linearization from qpdf-manual.pdf. It's a small file, and
removing the dependency on the qpdf executable significantly shortens
build times.

9a5d16a403 Prepare for docbook -> rst: replace SGML entitles 
We were using SGML entities for various non-ASCII characters so they
could convert properly for both HTML and print, but this is no longer
necessary as we move from docbook to RST, so just replace them. Note
that the conversions done by sphinx automatically handle "smart
quotes", so it works to just use regular quotes in place of &LDQUO;
and &RDQUO;.

78206a4651 Prepare for docbook -> rst: protect some XML elements 
Pandoc docbook -> rst fails to convert the following elements, so
change them to @1@tag@1@ ... @2@tag@2@ for later processing. This way,
they will survive the conversion, and we can deal with them later.

f721fed9d6 doc: Replace Gajic with Gajić (finally) 
With docbook, this was not converted properly in the PDF version, but
since we are moving out of docbook, we can just put the Unicode
character in the source.
