Apply GUC name from central table in more places of guc.c

Browse Source 
The name extracted from the record of the GUC tables is applied to more
internal places of guc.c.  This change has the advantage to simplify
parse_and_validate_value(), where the "name" was only used in elog
messages, while it was required to match with the name from the GUC
record.

pg_parameter_aclcheck() now passes the name of the GUC from its record
in two places rather than the caller's argument.  The value given to
this function goes through convert_GUC_name_for_parameter_acl() that
does a simple ASCII downcasing.

Few GUCs mix character casing in core; one test is added for one of
these code paths with "IntervalStyle".
