altos: Try RDF mode for TX calibration
Trying to get the radio to stop modulating the carrier when
calibrating the radio, we'll try RDF mode which says no preamble or
sync data. This might shift the frequency though?

altos: Flush the on-board mega log after every sample interval.
SPI flash parts don't need flushing, but the SD card does. Make sure
the SD card contents are sane after every logging interval has passed
by flushing all dirty blocks to the device.

ao-tools/ao-stmload: Be smarter about ELF parsing. Retry open on failure.
Figuring out what goes where is tricky; turns out we want to pull all
of the sections that map inside any program area that is supposed to
be loaded from the file.
So, we walk the program headers, then walk all of the section headers
looking for those that suck data from the same portion of the
file. Compute where in ROM each relevant section goes and build a full
ROM image in memory using that.
This patch also adds code to close and re-open the device if the first
open failed to do what we want. Much nicer to have the computer figure
out when the open succeeded rather than having people re-run the app.

altos/stm: Always check for idle IN buffer before sending
Unlike the AVR and CC1111 USB drivers, the STM usb driver queues IN
bytes in a local buffer instead of in the driver; this means that the
driver is queuing bytes while the previous IN packet is queued for the
host, which allows for overlapping execution.
It also means that when the local buffer is full, we must check to see
if the host has picked up the previous IN packet before trying to
queue another IN packet for transmission. This is done by always
waiting for the IN buffer to be ready before sending data.

altos: Do not release interrupts from any pollchar function
getchar relies on interrupts being blocked across the pollchar calls
and into the sleep call or it may go to sleep with data pending.
This prefixes all pollchar functions with _ to indicate that they are
to be called with interrupts blocked and eliminates all interrupt
manipulation calls from within the pollchar functions.

altos: Get CC115L radio working.
This involved figuring out which GPIO signal would reliably indicate
that the transmitter was finished; I ended up using the PA_PD bit for
this.
This also converts all of the radio users to the long packet support
as the CC115L has only a 64-byte fifo, not large enough to hold either
an RDF tone or a regular AltOS telemetry packet.
This also renames the public API for sending APRS packets from
ao_radio_send_lots to ao_radio_send_aprs, which is at least more
accurate. The workings of that API haven't changed, just the name.

This improves sequential file performance by taking advantage of any

The newer(?) chips in telegps didn't like the previous programming
