Summary: maxfwd module - internal corruption

Initial Comment:
The issue occurs when calling 'mf_process_maxfwd_header' or 'is_maxfwd_lt' script functions more than once within a single script execution
The second occurrence always returns as if the max forward header value has reached zero due to an issue with the temporary value (max forwards count) stored by the module being overwritten with zero during an int to string conversion

We are calling it more than once during a single execution to detect and trap possible call forwarding loops between accounts

Cheers!
