With the help of the PEP8 script, a semi-automated clean
of the code base was made, and effectively changing some
of the coding style rules of our code base:

 * No more 2 lines spacing among functions
 * No more combined module imports

In the end, it was going to be too difficult to take
into consideration E501 (line length > 80) errors and
W601 (.has_key() is deprecated), so these were ignored,
at least for now.

Quite often the only difference between HMP and QMP monitor
output is missing or additional space. Add '' around outputs
to help finding those bugs.

This test previously only checked, if any CPU contains 'current=True'.
With this patch it goes through all cpus and checks, whether the
'current=True' is set only for the last CPU.

Additionally this verification method works with all smp setups.

This script have coverd following qmp command:
query-hpet, query-kvm, query-mice, query-status
query-name, query-uuid, query-version, query-chardev
query-blockstats, memsave, pmemsave, query-cpus
cpu, query-vnc, query-block, query-commands
query-balloon, balloon, cont, stop
and a negative test with wrong command.

This script will check result by following way:
cmd_result_check = equal, will compare cmd_return_value with qmp command output.
cmd_result_check = contain, will try to find cmd_return_value in qmp command output.
cmd_result_check = m_equal_q, will compare key value in monitor command output and qmp command output.
cmd_result_check = m_in_q, will try to find monitor command output's key value in qmp command output.
cmd_result_check = post_contain, will try to find cmd_return_value in post command output.

This update is base on upstream QMP patchset.
