[PATCH 01/22] gweb: Leverage 'GWEB_HTTP_STATUS_CODE_UNKNOWN' mnemonic.

In the GWebResult structure, the 'status' data member is effectively
nullable with the GWEB_HTTP_STATUS_CODE_UNKNOWN mnemonic representing
the "null" value.

Consequently, use the GWEB_HTTP_STATUS_CODE_UNKNOWN mnemonic rather
than zero (0) to make that intent and pattern clear throughout the
code.
