Summary:                    [patch] Bridge application fails when both channels
have a similar name
Description: 
I've found that when two channels have a similar name (one channel name
contains the other one), for example "IAX2/Corp-1" and "IAX2/Corp-16548",
the Bridge application fails giving the following warning message "Unable
to bridge channel IAX2/Corp-1 with itself".

It's due to the fact that we are comparing only the first 'n' characters
(with strncmp) of both strings where 'n' is the lesser of both string
lengths. The problem can be solved by comparing the whole strings with
strcmp instead of strncmp.

  Fix channel name comparison for bridge application.
  
  The channel name comparison was not comparing the whole string and
therefore
  if one channel name was a substring of the other, the bridge would fail.
