Summary:                    [patch] new CLI commands for handling dialplan
variables and name standartization for the old ones
Description: 
Some commands like 'core set global' should actually be called 'dialplan
set global' as they deal with dialplan variables directly (they even state
that in their help messages), so I decided to change them after commenting
about it on #asterisk-dev. I'm not sure about the consequences of it since
a deprecated warning should be printed, but I will let it to someone more
experienced to decide.

Since there are CLI commands to set new global and per channel variables I
also decided to create equivalent ones to unset these variables as they'd
stay in memory forever until a reload or restart is executed. Not good, now
I can unset them :-)

Ultimately there was not a way to list all those per channel variables set
with 'dialplan set chanvar <channel> <name> <value>', except parsing the
very long output of DumpChan(). I created a command called 'dialplan show
chanvar <channel>', using the same idea from 'show globals' and dumping all
variables associated with the given channel.

caio1982:  Setting a variable to the empty string and setting a variable to
NULL do two different things.  Please either eliminate the unset or make it
set to the empty string.
