Summary:                    [patch] app_chanspy crashed so-as "chanspy_ds.lock"
has random values
Description: 
Hi.

 Inside function common_exec() declared struct chanspy_ds chanspy_ds, that
contain "ast_mutex_t lock".

 This lock is not initialized and contain random values from stack heap.
This may cause random crash in call to:
ast_mutex_init(&chanspy_ds.lock);
or 
ast_mutex_lock(&chanspy_ds.lock);

In my BSD box with DEBUG_THREADS options enabled, this application crashed
permanently on exit in ast_mutex_lock(&chanspy_ds.lock); point.
