[PATCH 0/2] util/log: Make the per-thread flag immutable

[Greg Kurz]

While working on the "util/log: Always send errors to logfile when daemonized"
series [1], I've encountered some issues with the per-thread flag. They stem
from the code not being designed to allow the per-thread flag to be enabled
or disabled more than once, but nothing is done to prevent that from
happening. This results in unexpected results like the creation of a log
file with a `%d` in its name or confusing errors when using the `log`
command in the monitor.

I'm posting fixes separately now in case it makes sense to merge them during
soft freeze. If so, I'll open an issue as explained in this recent mail [2].
