b67d3cc6ea Remove RF API header files 
xxwares ship these headers now, so we will switch to using those versions. The exceptions are IEEE API headers, which are for not part of xxwares, so we have to keep them locally for now.

8ab0522cec Fix PROP mode channel switching 
If `NETSTACK_CONF_RADIO.set_value(RADIO_PARAM_CHANNEL, ...)` is called when radio is on, it will fail to apply the channel change, because it won't re-send `CMD_PROP_RADIO_DIV_SETUP` and `CMD_PROP_FS`. This commit fixes this condition, by making sure the correct commands are sent to the radio.

2039b3a552 Use ccaInfo.ccaState to decide whether CCA is complete 
This commit changes the logic of `get_cca_info()` in the CC26xx IEEE mode driver. We now use the command's return status bits to determine whether the radio's CCA monitoring function has concluded, instead of drawing conclusions based on RSSI readings.

16f56abfad Wait for a valid RSSI reading in CC13xx/CC26xx RF drivers 
As discussed in #1341, the current CC13xx/CC26xx IEEE mode driver sends `CMD_GET_RSSI` once and returns the RSSI reading uncondtionally. This happens within the `get_rssi()` function.

This logic is broken if `get_rssi()` is called with the radio off. The function will make sure to turn on the radio first, but it does not make sure the RSSI reading is valid, which only happens a number of symbol periods after the radio enters RX. The outcome is that `NETSTACK_RADIO.get_value(RADIO_PARAM_RSSI, ...)` will always return -128 (meaning that RSSI is unavailable) if the radio was off at the time of calling the function.

The same condition affects the prop mode driver.

This commit changes the logic of `get_rssi()`:
* For PROP mode, if `CMD_GET_RSSI` returns an invalid RSSI, we send it again. For unknown reasons, `CMD_GET_RSSI` on occasion returns 0, so we ignore that value too.
* For IEEE mode, we use `CMD_IEEE_CCA_REQ` and we inspect the value of `ccaInfo.ccaEnergy` of the return structure. If the value is 0x02 (Invalid), we send the command again.

Fixes #1341
