Use the existing readline history function we are utilizing
to provide persistent command history across instances of qmp-shell.
This assists entering debug commands across sessions that may be
interrupted by QEMU sessions terminating, where the qmp-shell has
to be relaunched.

The qmp-shell property parser currently rejects attempts to
set string properties to the empty string eg
(QEMU) migrate-set-parameters tls-hostname=
Error while parsing command line: Expected a key=value pair, got 'tls-hostname='
command format: <command-name> [arg-name1=arg1] ... [arg-nameN=argN]
This is caused by checking the wrong condition after splitting
the parameter on '='. The "partition" method will return "" for
the separator field, if the seperator was not present, so that
is the correct thing to check for malformed syntax.

Pretty printing of JSON responses is important to be able to understand
large responses from query commands in particular. Unfortunately this
was broken during the addition of the verbose flag in
commit 1ceca07e48ead0dd2e41576c81d40e6a91cafefd
Author: John Snow <jsnow@redhat.com>
Date: Wed Apr 29 15:14:04 2015 -0400
scripts: qmp-shell: Add verbose flag
This is because that change turned the python data structure into a
formatted JSON string before the pretty print was given it. So we're
just pretty printing a string, which is a no-op.
The original pretty printer would output python objects.
(QEMU) query-chardev
{ u'return': [ { u'filename': u'vc',
u'frontend-open': False,
u'label': u'parallel0'},
{ u'filename': u'vc',
u'frontend-open': True,
u'label': u'serial0'},
{ u'filename': u'unix:/tmp/qemp,server',
u'frontend-open': True,
u'label': u'compat_monitor0'}]}
This fixes the problem by switching to outputting pretty formatted JSON
text instead. This has the added benefit that the pretty printed output
is now valid JSON text. Due to the way the verbose flag was handled, the
pretty printing now applies to the command sent, as well as its response:
(QEMU) query-chardev
{
"execute": "query-chardev",
"arguments": {}
}
{
"return": [
{
"frontend-open": false,
"label": "parallel0",
"filename": "vc"
},
{
"frontend-open": true,
"label": "serial0",
"filename": "vc"
},
{
"frontend-open": true,
"label": "compat_monitor0",
"filename": "unix:/tmp/qmp,server"
}
]
}

Add a verbose flag that shows the QMP command that was
constructed, to allow for later copy/pasting, reference,
debugging, etc.
The QMP is converted from a Python literal to JSON first,
to ensure that it is viable input to the actual QMP parser.
As a side-effect, this JSON output will helpfully show all
the necessary conversions that were performed on the input,
illustrating that "True" was transformed back into "true",
literal values are now escaped with "" instead of '', and so on.

Add a special processing mode to craft transactions.
By entering "transaction(" the shell will enter a special
mode where each subsequent command will be saved as a transaction
instead of executed as an individual command.
The transaction can be submitted by entering ")" on a line by itself.
Examples:
Separate lines:
(QEMU) transaction(
TRANS> block-dirty-bitmap-add node=drive0 name=bitmap1
TRANS> block-dirty-bitmap-clear node=drive0 name=bitmap0
TRANS> )
With a transaction action included on the first line:
(QEMU) transaction( block-dirty-bitmap-add node=drive0 name=bitmap2
TRANS> block-dirty-bitmap-add node=drive0 name=bitmap3
TRANS> )
As a one-liner, with just one transaction action:
(QEMU) transaction( block-dirty-bitmap-add node=drive0 name=bitmap0 )
As a side-effect of this patch, blank lines are now parsed as no-ops,
regardless of which shell mode you are in.

This includes support for [] expressions, single-quotes in
QMP expressions (which is not strictly a part of JSON), and
the ability to use "True", "False" and "None" literals instead
of JSON's equivalent true, false, and null literals.
qmp-shell currently allows you to describe values as
JSON expressions:
key={"key":{"key2":"val"}}
But it does not currently support arrays, which are needed
for serializing and deserializing transactions:
key=[{"type":"drive-backup","data":{...}}]
qmp-shell also only currently accepts doubly quoted strings
as-per JSON spec, but QMP allows single quotes.
Lastly, python allows you to utilize "True" or "False" as
boolean literals, but JSON expects "true" or "false". Expand
qmp-shell to allow the user to type either, converting to the
correct type.
As a consequence of the above, the key=val parsing is also improved
to give better error messages if a key=val token is not provided.
CAVEAT: The parser is still extremely rudimentary and does not
expect to find spaces in {} nor [] expressions. This patch does
not improve this functionality.

As another convenience to allow using commands that expect a dict as

qmp-shell hides the QMP wire protocol JSON encoding from the user. Most
of the time this is helpful and makes the command-line human-friendly.
Some QMP commands take a dict as an argument. In order to express this
we need to revert back to JSON notation.
This patch allows JSON dict arguments in qmp-shell so commands like
blockdev-add and nbd-server-start can be invoked:
(QEMU) blockdev-add options={"driver":"file","id":"drive1",...}
Note that spaces are not allowed since str.split() is used to break up
the command-line arguments first.
