Subject: [PATCH] Always choose highest requested debug level
Allowing the CLI to lower the debug level specified in a config file
is dubious, and previously broken since we don't distinguish "default
value" from "explicitly requested value of 0" in popt. This resulted
in "Debug Enabled (level: 0)" even when the log level was not actually
0, which is confusing for users.
Remove the gp_debug_args() function since it is no longer used.
