[PATCH 2/3] gitweb: rename gitweb_check_feature to gitweb_get_feature

[Junio C Hamano <gitster@pobox.com>]

The function is about retrieving the configuration parameter list for the
feature.  A more robust way to check if a feature is enabled is introduced
in the next patch, and the function will be called gitweb_check_feature.

Signed-off-by: Junio C Hamano <gitster@pobox.com>

 * The earlier "fix ctags and friends" is the 1/3; this shows how I would
   have liked to see your patches as a reviewable series.  The end result
   is almost identical.
