Summary:                    [patch] Only one custom feature can be executed
simultaneously
Description: 
On an asterisk server, there can be only one feature executed
simulatenously.

Ex: in feature.conf

define a feature such as

[applicationmap]
playmessage => **3,,callee,Macro,play-long-message

in extention.conf, define the attached macro

[macro-play-long-message]
exten => s,1,Playback(longmessage)

If you call in an extention with this feature activated (in the variable
DYNAMIC_FEATURE), the macro can be triggered by pressing '**3'.

If you make a second call to the same extention and try to trigger the
SAME macro / feature, the second chan hangs until the first chan has
completed the execution of the feature.

Fix an issue that made it so you could only have a single caller executing
a custom feature at a time.  This was especially problematic when custom
features ran for any appreciable amount of time.

The fix turned out to be quite simple.  The dynamic features are now
stored
in a read/write list instead of a list using a mutex.
