Reimplement FastCGI interface

Due to licensing restrictions that actually don't allow anybody to use
the libfcgi code without prior approval from Open Market, which is
impossible to obtain - we decided to reimplement this interface from
scratch.  The result is actually slightly faster, and more importantly,
clear of any copyright issues.
