Commit fixes from Gmond_python_modules
gmetad: Add wildcard support to gmetad http query interface.

The character '*' is treated as a wildcard. A query for "/*/*/metric_name"
would include all metrics named "metric_name" from all hosts. This change
does not affect the non-http query interface.

Fix bug for carbon timeout.

While trying to modify carbon_timeout using gmetad.conf
noticed timeout wasn't affecting actual socket timeout.
this was due to a bug in rrd_helpers.c while checking the
configuration value of the carbon_timeout variable in
gmetad.conf
and relying on the default 500 ms value.

Credit for the discovery of the bug goes to Leonid
