add POWER_LINE
...
The RF receiver's output is AC-coupled to the discriminator. At
`rfen(1)` the threshold is not well centered. This patch send a few
characters before the real messages, when POWER_LINE is set.
The string is not (yet?) configurable. 0xaa 0xaa 0xff 0x0a. The first
two characters are quick single bit switches. The third character is
basically a high level, to add some delay with an idle line. Finally, a
line feed, to separate the noise from the message.

bate: reduce standby current into pins
...
MCLK and DOUT randomly stick at high or low when the µC enters standby
mode.
MCLK TCA0 WO0 is properly disabled to keep the pin at low level. A high
level pushes current into the pressure sensor.
DOUT input pullup is not enabled. A low level on DOUT (LSB of the
temperature) pulls current from the pullup.

Most uart code is now in `uart_tx.S`.
Code close to the hardware stays in `uart.c` to use `io.h`.
The .S does not use the CPP, yet.

uart: rework uart_busy
...
- implement `tx()` in asm, does not work yet!
- enable TXC interrupt, to be woken when the uart is done
in order to power down. Alias the DRE interrupt.
- Rework `send_char()` and `send_str()`.
- Remove …_nosleep() and `panik()`.
- Better account for volatile-ness of buffer pointers.
