New Revision: 254050

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=254050
Log:
Exit native bridging early for greater timing accuracy with warnings

This changes native bridging to break one millisecond early so that the more
accurate timeval calculations done in the generic bridge can be performed using
the bridge config. Currently the time between exiting native bridging slightly
late can sometimes cause a large enough discrepancy for warnings to be missed.
For the record, 1.4 does not attempt to native bridge at all when warnings are
enabled.

(closes issue #15815)
