ftp: allocate the wildcard struct on demand

Browse source 
The feature is rarely used so this frees up data for the vast majority
of easy handles that don't use it.

Rename "protdata" to "ftpwc" since it is always an FTP wildcard struct
pointer. Made the state struct field an unsigned char to save space.

Closes #10639
