Clean up imports across the board in tp-qemu. The criteria
followed was:

1) Remove unnecessary imports
2) Turn multi imports from a single entry point to one
   import per line. This increases both patch and
   source code readability.
3) Separate blocks of imports with a line:
   * Python standard library imports
   * Autotest imports
   * virttest imports
   * Internal tp-qemu imports
4) Remove try/except blocks refering autotest libs and
   stick with the virttest.staging copy

This paves the way for the future removal of autotest
references, replacing those references with avocado ones.

User wants to collect sysinfo of host/guest, but different users
might have different requests, and many kinds of system might be
used. So I would like to use custom-built scripts to collect the
information that will make users happy.

User needs to add shell scripts to autotest/client/tests/virt/shared/scripts/,
and set the script path in config file.

eg:
 #log_hostinfo_script = scripts/rh_perf_log_hostinfo_script.sh
 #log_guestinfo_script = scripts/rh_perf_log_guestinfo_script.sh
 #log_guestinfo_exec = bash
 #log_guestinfo_path = /tmp/log_guestinfo.sh

Then the script output will be saved to $test.resultsdir/sysinfo,
analyzer can use 'diff' to compare the system information when
regression occurs.

I will send a pull request to add to example scripts to virt-tests repo.

When we enable multiple queue, there are multiple virtio
input/output interrupts in guest.

This patch counts interrupt for each queue, and output
a summary in result.

This patch also moves the volatile items to the end of
record list. Then the avg_update in perf.cfg should be

Some times when boot guest with two nics, the second nic can not

The wait_for_get_address will try to renew guest ip and try to get

The largest timeout_netperf_start should be int(l) * 0.5,
if netperf threads start all at once, it will still need
int(l) * 0.5 time waste. Therefore, the netperf_start_timeout

There's no need to have the name of the "run_<name>" method (main
test entry point) depend on the test name. So, for simplicity sake,
let's just name the test entry point "run".

I have decided to not fallback gracefully to the previous naming
convention as I believe this can lead to confusion in the future.

There is a background tcpdump thread that records DHCP leases
in the env["address_cache"] dictionary. Sometimes, this thread
might write to this dictionary while the environment object is
being saved, triggering a RuntimeError in virt-test.

So the solution involves:

1) Creating a save lock, (a threading reentrant lock object),
that is acquired by the env.save() method when it wants to
save env.data to a pickle file, and for methods that alter
env.data.

2) Move the tcpdump thread to a env object attribute, rather
than one of the keys of env.data, given that the lock object
can't be pickled.

With the implementation of env.save_lock, we can also fix
the problem identified by the locking unittest. The base of
the solution was Pavel's idea, including a good deal of the
implementation, so kudos to him.

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.

Currently we use many threads/heavy control sessions to launch many
clients, Autotest takes too much of the host resources.

This patch introduces an agent script, it'll be executed inside the
client system to launch multiple sessions, and Autotest only needs
to use one background thread to control clients.

We can consider to process the raw results in this agent script in
future, if it can help to simplify the case.
