System memory functions refactoring + addition of memory percentage

[giampaolo]

Currently we have:

psutil.TOTAL_PHYMEM
psutil.avail_phymem()
psutil.used_phymem()

psutil.total_virtmem()
psutil.avail_virtmem()
psutil.used_virtmem()

I think it makes sense to deprecate them and provide 2 separate functions 
instead, returning a namedtuple:

>>> psutil.get_phymem()
mem(total=..., used=..., free=..., percent=...)
>>>
>>> psutil.get_virtmem()
mem(total=..., used=..., free=..., percent=...)



Pros:
- it would be compliant with  the rest of the API which massively uses 
namedtuples (see 
https://code.google.com/p/psutil/source/browse/tags/release-0.2.1/psutil/_common.py#37 )
- more compact
- extra "percent" value which is what we usually need when we do system monitoring
- the total physical memory can be recalculated every time solving the issue 
related with virtualized OSes changing it at runtime (see original proposal: 
https://code.google.com/p/psutil/issues/detail?id=140#c5 )

Implemented in r1011 and r1012 for FreeBSD and Windows.
OSX implemented in r1013 (not tested - Jay please close this one once you're 
verified everything's ok).

Any idea when 0.2.2 might roll out?  I'd love to use this.

Python 2.6 on OS X 10.6

[user@host ]$ python -c 'import psutil; print psutil.virtmem_usage()'
usage(total=2147483648L, used=1403551744L, free=743931904L, 
percent=65.400000000000006)
[user@host ]$ python -c 'import psutil; print psutil.phymem_usage()'
(4294967296L, 4227334144L, 67633152L)

Does that look right? I'm not sure if the phymem_usage() results should be 
showing named values?

Not sure when exactly but it's close.
What's missing is Process.terminal and disk information implementations for OSX.

No, it should return a namedtuple.
ps: I'm at euro python now.
