Subject: [PATCH 42/64] perf probe: Make --funcs option exclusive

From: Masami Hiramatsu <masami.hiramatsu.pt@...achi.com>

The --funcs option should be given exclusively.  This adds
PARSE_OPT_EXCUSIVE flag on --funcs (-F) option.

Without this, 'perf probe --funcs -l' just shows the list of probes.

With this, it shows error message correctly.

This also fixes the help message and the documentation.
