[PATCH 2/2] Smart-http: check if repository is OK to export before serving it

[Tarmigan Casebolt <tarmigan+git@gmail.com>]

Similar to how git-daemon checks whether a repository is OK to be
exported, smart-http should also check.  This check can be satisfied
in two different ways: the environmental variable GIT_HTTP_EXPORT_ALL
may be set to export all repositories, or the individual repository
may have the file git-daemon-export-ok.
