fbe528d8b6 rust: Add assertion that input length is at least 0 for AES 
It doesn't look like the AES engine can handle 0-sized input. This makes
sense, in a way, as it is an edge case and in most cases a no-op. Only
in GCM mode, where there one might want to compute a tag over a 0-byte
input, would this come up.

7cc906d349 rust: Don't require resetting AES engine before every use 
When using the AES engine in GCM mode, the hardware *requires*
verifying a tag even if we don't care about the result. Otherwise it
will hang in unfinished state, and needs a reset every time.

By going through these motions (like the SDK does) this costly reset can
be avoided.

ab95e18ba8 linux: Handle "SEND FAIL" response 
UDP sends can fail and then the ESP module returns "SEND FAIL";
we need to handle this, otherwise we'll never consider the send finished.

afde09e6cc linux: Don't set VTIME in UART configuration for esptun

the UART FIFO, no timing required.

c261d4dcc7 linux: Simplify esptun by getting rid of some helper functions

7cbb10693e linux: Set timeout argument on poll() properly 
`0` for the timeout means *return immediately* instead of
*wait forever*. This is absolutely unnecessary, so change
the argument to `-1` which does mean *wait until something happens*.

aab7c0a84b linux: Solve an issue with incomplete packets 
esp_read_responses was throwing away the buffer contents between
invocations, which is not a good idea if there might be a (partial)
async notification such a a received packet in there.

4d987f0d7d rust: Important correction to board definition comment 
WIFI_RX and WIFI_TX are named from the perspective of the ESP8285,
so they need to be connected RX<->TX and TX<->RX to be used.

there is a release.
