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.

63c7eefe9d replaceStreamData: accept uninitialized filter/decode_parms
These mean to leave the original values alone. This is needed for
reconstructing streams from JSON given that the stream data and stream
dictionary may appear in any order in the JSON.

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.

9a0e9a1a9e Remove offset from missing /Root error
The last offset is irrelevant to not being able to find /Root.

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.

4c7cfd5cbc JSON reactor: improve handling of nested containers
Call the parent container's item method before calling the child
item's start method so we can easily know the current nesting level
when nested items are added.

moddify -> modify. Also carefully spell checked all remaining keys by

relying on visual proofreading. That was the only one.

a9fbbd5dca Objectinfo json: write incrementally and in numeric order
This script was used on test data:

def json_dumps(data):
    return json.dumps(data, ensure_ascii=False,
                      indent=2, separators=(',', ': '))

for filename in sys.argv[1:]:

948de60990 Objects json: write incrementally and in numeric order
The following script was used to adjust test data:

----------
#!/usr/bin/env python3
import json
import sys
import re

def json_dumps(data):
    return json.dumps(data, ensure_ascii=False,
                      indent=2, separators=(',', ': '))

for filename in sys.argv[1:]:
    with open(filename, 'r') as f:
        data = json.loads(f.read())
    if 'objects' not in data:
        continue
    trailer = None
    to_sort = []
    for k, v in data['objects'].items():
        if k == 'trailer':
            trailer = v

dc9b7287cd Top-level json: write incrementally
This commit just changes the order in which fields are written to the
json without changing their content. All the json files in the test
suite were modified with this script to ensure that we didn't get any
changes other than ordering.

----------
#!/usr/bin/env python3
import json
import sys

def json_dumps(data):
    return json.dumps(data, ensure_ascii=False,
                      indent=2, separators=(',', ': '))

for filename in sys.argv[1:]:
    with open(filename, 'r') as f:
        data = json.loads(f.read())
    newdata = {}
    for i in ('version', 'parameters', 'pages', 'pagelabels',
              'acroform', 'attachments', 'encrypt', 'outlines',
              'objects', 'objectinfo'):
        if i in data:
            newdata[i] = data[i]
print(json_dumps(newdata))
