qmp: fix handling of cmd with equal mark in qmp-shell
qmp-shell splits the argument and value of input command
by equal mark("="). But there are commands whose values
include equal mark themselves, and the json built by
qmp-shell will not correct. For example, when using NBD as
the target of block-backup command, the input
"block-backup target=nbd+unix:///drive0?socket=/tmp/nbd.sock"
will fail, because the json built will be as follows:
{
"execute":"block-backup",
"arguments":{"target":"nbd+unix:///drive0?socket"}
}
Fix it by joining the sections split by equal mark excluding the
first section in __build_cmd function when the length of sections
is larger than two.

qmp-shell converts only integer arguments and the rest
is assumed to be strings which are faithfully sent as
quoted strings by json. But QEMU refuses to accept qmp
command with boolean argument whose value is escaped
as string.
Fix it by special-casing true/false keywords and store
value as corresponding boolean.

Add a '-p' arg to the QMP/qmp-shell test program, which uses
the python pprint module to pretty-print the dictionary
returned from a command
$ qmp-shell -p /tmp/qemu

In which qmp-shell will exclusively use the HMP passthrough feature,
this is useful for testing.
Example:
# ./qmp-shell -H qmp-sock

As sending "qmp_capabilities" on session start became mandatory, both
python examples were broken.

This is a very simple shell written in Python for demonstration
purposes.
Unfortunately it's a bit awkward right now, as the user has
to specify the arguments names and the printed data can be
a raw dictionary or list, like the following example:
(QEMU) pci_add pci_addr=auto type=nic
{u'slot': 5, u'bus': 0, u'domain': 0, u'function': 0}
(QEMU)
It's worth to note that the shell is broken into two files.
One is the shell itself, the other is the QMP class which
handles the communication with QEMU.
