devel/cdecl: update to 11.7

ChangeLog:
Cdecl keywords
When an unexpected name token is encountered, if said token is a cdecl keyword, it's now mentioned in the error message:

cdecl> declare ptr as pointer to void
               ^
16: syntax error: "ptr": name expected ("ptr" is a cdecl keyword)
Additionally, cdecl keywords are now also offered in suggestions.

register arrays
register arrays are now correctly allowed.

Zero-sized arrays
Zero-sized arrays are now correctly forbidden.

No files as arguments
Command-line arguments were treated as files if they weren't commands.
This dubious use-case was a hold-over from the original cdecl and has
been removed. (If you want to read a file use -f.)
