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.

a967a58ed3 [baremetal] Avoid narrow loop counters etc 
Use `uint_fast8_t` instead of `unsigned char` in various loop-type
situations. This avoids the need for a 16 or 32-bit system to insert
explicit narrow-to-8-bit instructions.

Not the result of an exhaustive source analysis, rather inspecting
the disassembly output for a cut-down Cortex-M0+ build looking for
UXTB etc instructions, so there could well be more in the complete
configuration.

585e9e0922 Add MBEDTLS_SSL_CONF_TRANSPORT 
Follow the model of `MBEDTLS_SSL_CONF_ENDPOINT`. This saves a small
amount - most of the saving was already acheived via`
MBEDTLS_SSL_TRANSPORT_IS_TLS` but we can scrape out a little more by
totally eliminating `ssl->conf->transport` references.
