Fixed a logic error with my recent gzip patch

The gzip patch I submitted recently assumes that apr_socket_data_get
returns with an error code if there is no data in the socket;
however, this is not always the case. This patch explicitly checks
for the data we want instead of relying on the error code to
indicate its presence.

Reduce CPU utilisation of gmond running in deaf mode

TCP thread should only poll every 100ms and should not start
at all if the gmond is configured to be deaf. Fixes #85.

Add configurable graphite path. Fixes issue 87

Deprecate the "graphite_prefix" attribute in favor of "graphite_path"
which is configurable via macros (%s %m %h). Sane defaults ensure that
existing configurations are not broken by this change. This should solve
issue 87 and any future needs in its general direction. I've moved code
relating to graphite and memcached from rrdhelpers.(c|h), to
export_helpers. This is housekeeping that reflects how those features
should have been implemented in my original ganglia patch.
