Hi,

replacing my cgit install by gotwebd, got annoyed because by default
gotwebd displays all repositories while cgitrc allows to list the
repositories to display in the index.

discussing it with stsp@ we pondered about adding per-repo settings, but
he suggested reusing the magic 'git-daemon-export-ok' file, that
git-daemon checks for existence to figure out if it should export a
repo.

so here's a diff that :
- adds respect_exportok boolean flag to the config, defaulting to
  false -> no change to existing configs needed
- if the flag is true, check that the git-daemon-export-ok magic file
  exists in the repo, and returns GOT_ERR_NOT_GIT_REPO if it doesnt
  exist

this way, i can have "hidden" git repos in /var/www/htdocs/git that can
still be cloned only by the ones who know their name, and the same repos
listed in https://cgit.rhaalovely.net/
are seen in https://cgit.rhaalovely.net/gotwebd/

feedback welcome.

Landry
