Summary: making Python LC_NUMERIC agnostic

Initial Comment:
  This patch offers conversion string<->float
conversion functions that are locale agnostic.  This
way, Python will be able to run perfectly even when
LC_NUMERIC is set to something other than C.  It
happens frequently when using external modules that
these modules change LC_NUMERIC without python knowing
about it.  It will never stop happening, unfortunately,
so it is best to make python not depend on LC_NUMERIC
being always set to 'C'.

  I have to incorporate glib code, otherwise what happens if
glib is not installed? It is my intention that the current
behaviour *never* be preserved.
  Well, that's not exactly an accurate statement.  What I
mean is that str() and float() should keep the current
C-locale behaviour.  
  However, underneath these python functions we could have
LC_NUMERIC set something other than 'C'.  This is vital for
some modules, like GTK+, that depend on LC_NUMERIC to be set
the locale dependent value, otherwise it behaves different
from what the user expects.

I recommend that you do not incorporate the code of glib,
but rather arrange to link with glib (perhaps only if
activated by --with-glib). If no guaranteed-C-locale strtod
is available, the current behaviour should be preserved.
