[GENERAL] VARCHAR to CIDR type cast : external function for 6.5

[Nicolas Huillard]

With the patch from Alex Pilosov (7.1), I was able to create external functions (6.5) 
to cast TEXT type to CIDR.
These function allow things like :
        SELECT text_inet(text_field);
        SELECT ... FROM ... WHERE text_cidr(text_field) >> '192.168.200.1'::inet;
...which are impossible with the current Postgres.
The code has greatly changed from 6.5 to 7.1, so these function might help users of 
older versions...
Extract the tarball, compile and install (tested on Linux/Postgres 6.5.3).
