shuffle some code to handle all the page types in the switch. ok tracey@

gotd still requires the config file, of course, but gitwrapper must treat is as optional and remain silent if the file cannot be found.

Since we're going to unconditionally execute gotsh or git-*-pack, don't bother fork()ing and having the main process to wait(2), just execle()! ok stsp@

simplify gotweb_process_request more, handling all the pages inside the big switch. There's only one entrypoint for rendering the templates gotweb_render_page() that takes the page' content as argument. The only real difference is that gotweb_render_index() now skips directory entries which fails to handle. ok tracey@

If a short read happens, or if all the fastcgi record to read don't fit in the buffer, gotwebd fails to continue reading and hits the timeout. If this happens before gotweb_process_request is called, it will crash in gotweb_free_transport since c->t will be NULL. This register the event with EV_PERSIST so fcgi_request is called again when there's more to read and guards gotweb_free_transport. It also makes spaces for the records as soon as they're successfully parsed. With lots of help from stsp ok stsp@

Escape the path to the repository when connecting via SSH. This is needed if the path contains spaces, quotes or other "funny" characters, but also by git-shell which requires the argument to be surrounded by single-quote characters. Issue with git-shell reported by James Cook, fix based on an initial diff by stsp@. ok stsp@

`got log' is ran twice against $testroot/repo so log-repo and log-repo-clone are identical. Instead, run `got log' on the clone repo the second time. ok stsp@

Fixes a race condition on NFS where the file's modify time may change while the file is being edited, causing the editor to complain. OK stsp
