Feature/change loglevel

[FeepingCreature]

Add loglevel.c, a system-level tool to directly modify the log level of a running D process using util.log.

When I told the AI to rewrite this program in idiomatic D, the AI praised itself for how much better the code was then. Maybe you can even reuse data types this way?

[FeepingCreature]

Lol. The simple answer is I have this installed setuid root internally, and I just barely trust the C functions I call to run setuid root... I do not trust the D runtime. I'm not even sure I trust it to run sudo tbh.

When I'm messing with internals like this, I want the absolute minimum of abstraction.

[linkrope]

Yeah: trust is an issue... Also: what's the related means, for example, for TypeScript services?
Should we consider the possible requirement that the level change survives a service restart?

[FeepingCreature]

I mean... then you start looking at things like config db and notifications and have to pull a lot of complexity in. That's why we didn't have any feature that could do this, despite it being useful, for years.

Replaced PR with a simple link to the branch I pushed to the repo.
