pyGlobus features needed

[Robert Olson]

Ivan wanted me to send this out for today's discussion with Keith..

The things that were added to the older pyGlobus that we depend on include 
support for programmatically creating proxies, including the passing of 
passwords into the gpi function.  The primary patch for this can be seen here:

http://fl-cvs.mcs.anl.gov/viewcvs/viewcvs.cgi/pyGlobus/src/sslutils.i.diff?r1=1.4&r2=1.5

but the latest code at

  http://fl-cvs.mcs.anl.gov/viewcvs/viewcvs.cgi/*checkout*/pyGlobus/src/sslutils.i?rev=1.11

has the various fixes that were required after the initial patches.

The related addition is the return of any underlying SSL or Globus errors 
as python exceptions instead of error codes or printed error messages. the 
primary patch that added those is here:

http://fl-cvs.mcs.anl.gov/viewcvs/viewcvs.cgi/pyGlobus/src/sslutils.i.diff?r1=1.10&r2=1.11

A minor change was the addition of the exposure of globus_libc_getenv and 
_setenv, in order to support runtime setting of GLOBUS_HOSTNAME:
