Summary:                    [patch] correctly reinit a variable and other more
substantial modifications to MARK2 echo canceller
Description: 
This is a patch in two parts. The first part adds a missing
reinitialisation of 'ec->Lu_i' after the echo can is restarted. Also, the
special case where 'ec->max_y_tilde = 0' has accounted for to prevent
triggering near constant false near-end speech detection when the channel
is very quiet, such as on PRI facilities.

The second part makes a stab at adding a couple of degrees of
instrumentation to the MARK2 canceller to aid in tuning constants. As well
the formatting has been somewhat normalised and various verbiage has been
stirred in to assist the lay reader.
