Hello ppl,

as we promised there is a new version with modifications you wanted us 
to do. It's complete package based on the newest GIT version.

[Changelog]
- new structure (tests_base.cfg, ...)
- improved log
- function get_stat() raise an error when access death VM
- get_stat() splitted into 2 functions, _get_stat() returns int, 
get_stat returns log string
- use of session.close() instead of get_command_status('exit;')
- PID of VM is taken using -pidfile option (RFC: It would be nice to 
have this in framework by default)
- possible infinite loop (i = i + 1)
- 32bit host supports 3.1GB guest, 64bit without limitation, detection 
using image file_name

[Not changed]
- We skip the merge of serial and parallel init functions as the result 
would be way more complicated (= more possible errors)
