 A 'b' option has been added which causes chan_local to return the actual channel that is behind it when queried. This is useful for transfer scenarios as the actual channel will be transferred, not the Local channel. If you have been using Local channels as queue members and having issues when the agent did a blind transfer this option may solve the issue.

 Fix a race condition that may happen between a sip hangup
 and a "core show channel" command. This patch adds locking
 to prevent the resulting crash.

 Fix the fact that global_variables 1) weren't being updated on reload (thanks for the report, Doug), and 2) weren't actually being appended to the list of profile variables because build_profile was called before the list was populated. Also needed to free the contents returned by load_file().
