remove uuid helper code
adding .gitignore files
detect stun packets in kernel module and pass them through
rename some stuff to avoid confusion
start implementing in-kernel AES en/decryption for SRTP

session key derivation complete
create crypto context for session keys
this implements in-kernel SRTP authentication
this happens in irq context, so use appropriate locking
implements in-kernel SRTP decryption (AES-CM)
implement AES-CM encryption and adding auth tag, which completes in-kernel AES-CM SRTP support
SRTP daemon<>kernel tie-in
copy back s_l number from kernel to daemon
aes-f8 goes kernel
count auth errors in kernel module
implement support for RFC 5761
better /proc output
array size should depend on the #define
kernel module compile fixes for kernels >= 3.10
prevent endless read of proc/status file
