cmdline/docs: add a required 'multi' keyword for each option
The keyword specifies how option works when specified multiple times:

 - single: the last provided value replaces the earlier ones
 - append: it supports being provided multiple times
 - boolean: on/off values
 - mutex: flag-like option that disable anoter flag

The 'gen.pl' script then outputs the proper and unified language for
each option's multi-use behavior in the generated man page.

The multi: header is requires in each .d file and will cause build error
if missing or set to an unknown value.

Closes #9759

Write the received protocol headers to the specified file. If no headers are
received, the use of this option will create an empty file.
When used in FTP, the FTP server response lines are considered being "headers"
and thus are saved there.
