Normally _should_run for mission is only ever true if _should_run for the
normal log is. There are exceptions though:
- the log buffer fails to allocate
- there was a write failure (e.g. due to SD card removal)
In that situation, the writer would not wait anymore but busy-loop.
There was a time window where if a task with higher priority than the main
logger thread would busy-loop, it would block both logging threads and the
watchdog would not trigger if the writer was in idle state.
This can happen for fast SD card writes.
It accesses kernel internal structures directly; this needs to be
worked out with some proper userspace-kernel interface

Need to log both, because on some systems the
information will come in directly as a
landing_target_pose message, and on others
it's coming in as irlock_report and then filtered
in PX4 to produce the landing_target_pose message.
If the board supports encrypting logfiles, but the parameter SDCARD_ALGORITHM is set to NONE,
the log should be written to the sdcard in plaintext format. This fixes a bug which caused
logger to hang in mutex instead.

The current practice of adding topics to the default set isn't scalable,
as it affects all setups.
By making sure topics are advertised on init, logger can just discard
topics that don't exist. This does not work for all topics, so topics are
specifically marked as optional. It can be extended to more topics later
on though.
This reduces the list of topics by ~35 on a pixracer configured as quad,
and reduces RAM usage by ~1KB.
CA: fix saturation computation
Since the CA matrix is normalized, the same scale applied to be used when using the effectiveness matrix
MCRateControl: use control_allocator_status to get saturation info
SDLOG_ALGORITHM for selecting the crypto algorithm
SDLOG_KEY for selecting the key in keystore to use with the algorithm.
for symmetric algorithms which are currently supported, this is just a free
slot to be used, the key is generated at logging start
SDLOG_EXCH_KEY for selecting an RSA2048 key for encrypting the SDLOG_KEY

- Generate a symmetric encryption key and a nonce value
- Use a public key in keystore to encrypt the symmteric key
- Write the encrypted key and the nonce value to disk into .ulgk, name matching with the encrypted log file
- use quick stream encryption to crypt the .ulg file contents
