* src/extras/libc.c: Implemented a wrapper around fork() and execve()
to spawn an external process and get its output. Only implemented for UNIX-style systems at present. * src/misc/httpd.c: New "handler" node type which bypasses the internal HTTPD behaviour. * modules/control/http: New --http-handlers option to dedicate particular extensions to external programs (PHP or Perl for instance). This is in accordance with the CGI/1.1 specification.
