Changes with nginx 1.7.10 10 Feb 2015

    *) Feature: the "use_temp_path" parameter of the "proxy_cache_path",
       "fastcgi_cache_path", "scgi_cache_path", and "uwsgi_cache_path"
       directives.

    *) Feature: the $upstream_header_time variable.

    *) Workaround: now on disk overflow nginx tries to write error logs once
       a second only.

    *) Bugfix: the "try_files" directive did not ignore normal files while
       testing directories.
       Thanks to Damien Tournoud.

    *) Bugfix: alerts "sendfile() failed" if the "sendfile" directive was
       used on OS X; the bug had appeared in 1.7.8.

    *) Bugfix: alerts "sem_post() failed" might appear in logs.

    *) Bugfix: nginx could not be built with musl libc.
       Thanks to James Taylor.

    *) Bugfix: nginx could not be built on Tru64 UNIX.
       Thanks to Goetz T. Fischer.
