Smart-http: check if repository is OK to export before serving it

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.

and the backwards-compatible dumb HTTP protocol, as well as clients
pushing using the smart HTTP protocol.
It verifies that the directory has the magic file
"git-daemon-export-ok", and it will refuse to export any git directory
that hasn't explicitly been marked for export this way (unless the
GIT_HTTP_EXPORT_ALL environmental variable is set).
By default, only the `upload-pack` service is enabled, which serves
'git-fetch-pack' and 'git-ls-remote' clients, which are invoked from
'git-fetch', 'git-pull', and 'git-clone'. If the client is authenticated,
