bug#14472: 24.3.50; Keybindings for cycling through semantic-symref results

[Jambunathan K <kjambunathan@gmail.com>]

This bug is in two parts:

1. Provide keybindings for cycling through semantic-symref results.  I
   don't see any right now.

2. Provide a more convenient and shorter prefix to replace existing 
   C-c ,

----------------------------------------------------------------
Some side notes.

(semantic-mode 1)

Atleast in C-mode, 

    Development->Navigate Tags->[Previous, Next] Tag bound to 
    C-c , n and C-c , p 

seem to be of questionable utility.  It apparently jumps to params (in
order) and function names.  More or less, what C-M-n or C-M-p what
achieves.

I was under the mistaken assumption that C-c , n and C-c , p cycle
through symref results created with C-c , g etc.  It is not so.

I think part of the confusion is because search functions (as in C-c ,
G) is mixed with non-search local navigation (C-c , p, C-c , n) on to
same prefix C-c ,.  As a rgrep user, I am quite happy with M-g M-n M-g
M-p bindings.
