[PATCHv2 0/2] fixes to gitweb feature check code

This is v2 of the gitweb feature check fix patch, which has now been
split into into a code patch and cleanup patch.

The first patch introduces git_get_feature() to clearly distinguish the
feature retrieval from the boolean feature check (which is kept at
git_check_feature()). The new function is used where appropriate.

The second patch cleans up use of git_check_feature(): since the
function now returns a boolean instead of an array, the often-used
construct
  my ($somevar) = git_check_feature('somefeat');
although still valid, becomes a rather clumsy stylistic choice, as it
introduces an unnecessary ambiguity. Make it clear that we're now
dealing with scalars by using scalar assignment.
