This patch adds a scheduler thread to the core and moves the heartbeat
event to use the new scheduler as an example.
Also The following features are implemented that use this scheduler:
sched_hangup dialplan application:
<action application="sched_hangup" data="+10 normal_clearing bleg"/>
** The cause code is optional and the optional bleg keyword will only hangup the
channel the current channel is bridged to if the call is in a bridge.
sched_transfer dialplan application:
<action application="sched_transfer" data="+10 1000 XML default"/>
** The last 2 args (dialplan and context) are optional
sched_broadcast dialplan application:
<action application="sched_broadcast" data="+10 playback:/tmp/foo.wav"/>
<action application="sched_broadcast" data="+10 playback!normal_clearing:/tmp/foo.wav"/>
** The optional !<cause_code> can be added to make the channel hangup after broadcasting the file.
sched_hangup api function:
sched_hangup +10 <uuid_string> normal_clearing
** The cause code is optional
sched_transfer api function:
sched_transfer +10 <uuid_string> 1000 XML default
** The last 2 args (dialplan and context) are optional
sched_broadcast api function:
sched_broadcast +10 <uuid_str> playback:/tmp/foo.wav
sched_broadcast +10 <uuid_str> playback!normal_clearing:/tmp/foo.wav
** The optional !<cause_code> can be added to make the channel hangup after broadcasting the file.
The new C functions in the core are documented in the doxeygen.

This addition lets you set artifical ringback on a channel
that is waiting for an originated call to be answered.
the syntax is
<action application="set" data="ringback=[data]"/>
where data is either the full path to an audio file
or a teletone generation script..
syntax of teletone scripts
LEGEND:
0-9,a-d,*,# (standard dtmf tones)
variables: c,r,d,v,>,<,+,w,l,L,%
c (channels) - Sets the number of channels.
r (rate) - Sets the sample rate.
d (duration) - Sets the default tone duration.
v (volume) - Sets the default volume.
> (decrease vol) - factor to decrease volume by per frame (0 for even decrease across duration).
< (increase vol) - factor to increase volume by per frame (0 for even increase across duration).
+ (step) - factor to step by used by < and >.
w (wait) - default silence after each tone.
l (loops) - number of times to repeat each tone in the script.
L (LOOPS) - number of times to repeat the the whole script.
% (manual tone) - a generic tone specified by a duration, a wait and a list of frequencies.
standard tones can have custom duration per use with the () modifier
7(1000, 500) to generate DTMF 7 for 1 second then pause .5 seconds

US Ring Tone [440+480 hz on for 2000ms off for 4000ms]
%(2000,4000,440,480)
ATT BONG [volume level 4000, even decay, step by 2, # key for 60ms with no wait, volume level 2000, 350+440hz {us dialtone} for 940ms
v=4000;>=0;+=2;#(60,0);v=2000;%(940,0,350,440)
SIT Tone 913.8 hz for 274 ms with no wait, 1370.6 hz for 274 ms with no wait, 1776.7 hz for 380ms with no wait
%(274,0,913.8);%(274,0,1370.6);%(380,0,1776.7)
ATTN TONE (phone's off the hook!) 1400+2060+2450+2600 hz for 100ms with 100ms wait

This changes the core to have the necessary tools to create
a speech detection interface.
It also changes the code in javascript (mod_spidermonkey)
there are a few api changes in how it handles callbacks
It also adds grammars as a system dir to store asr grammars
