ada61f05b3 AES: masked config: remove 176 bytes of zeroing on each AES finalize round 
On MBEDTLS_AES_128_BIT_MASKED+FI_COUNTERMEASURES config the rk_mask array
was unconditionally zeroed on each dummy finalization round even though
it will be zeroed after the loop too. Remove the repeated zeroing to increase
overall transfer speed on DTLS session by 17..20% on a Cortex-M4.

0241f81cbc AES: masked config: increase total transfer speed by 5% by removing zeroing 
On MBEDTLS_AES_128_BIT_MASKED config the overall DTLS transfer speed can be
increased by 3..5% or so on a Cortex-M4 by removing 472 bytes worth of
buffer zeroing done on each block {en|de}cryption. The buffer zeroings
were done before overwriting them on in masking code.

38c7f2d32f Refactor the immediate transmission feature 
The original way or handling it did not cover
message fragmentation or retransmission.
Now, the messages are always appended
to the flight and sent immediately, using 
the same function as normal flight 
transmission.
Moreover, epoch handling is different for this feature,
with a possibility to perform the usual retransmission
using previous methods.
