[Serusers] Anonymization/uac-module questions

[Elena-Ramona Modroiu]

I have just committed some fixes and improvements regarding the From URI 
replacement in UAC module. Instead of stateless approach with filtering 
all replies for restoring the From URI, it uses TM callback per 
transaction - this will reduce the the overhead due to detecting the 
replies of modified requests and restoring computation (no decoding is 
actually performed now in this case).

Also the update fixes the To URI restoring problem for replies to 
within-dialog requests which flow in the opposite direction - like BYE 
generated by callee.

Note: due to the fact that the modules/uac/docs/restore_from.patch was 
also updated, if you have it already applied, is better to remove the 
old one first (use patch -R) and than to update the module from CVS and 
apply again the patch.

Any feedback will be helpfully.
