Summary:                    [patch] ztdynamic double buffering on rx, statistics
Description: 
In current implementation:
1. If we have more than one TDMoE device, we'll have a slip/skip. 2 TDMoE
devices can have phase jitter.
2. We have no statistics (which is necessary).
3. ztdynamic can't be a master for zaptel (but why not ?)

---------------------------------------------------------------------- 
Here is a patched for dahdi.
dahdi_dynamic.c.patch:
 Implemented double buffering on rx.                                      
   
 Implemented procfs statistics.                                           
   
 fixed deadlock in dynamic_destroy called with spinlock.

dahdi_dynamic.c.printk.patch:
 printk -> module_printk

Running 2 PC's(synced from RTC) connected by TDMoE will show the problem
(slip counter will grow...)
