Added emulations of the C APIs in _locale to be used when the
_locale module is not enabled. They return the correct values
assuming the 'C' locale.

Added a new locale name aliasing engine which also supports
locale encodings, a feature which is used by the new default
encoding support in site.py.

*this* set of patches is Ka-Ping's final sweep:

The attached patches update the standard library so that all modules
have docstrings beginning with one-line summaries.

A new docstring was added to formatter.  The docstring for os.py
was updated to mention nt, os2, ce in addition to posix, dos, mac.

format(), str(), atof(), and atoi().  The last three are locale
sensitive versions of the corresponding standard functions (only for
numbers though); format() does general %[efg] formatting taking the
locale into account, optionally with thousands grouping.
