Fixed reparenting issue. PPID should be updated each refresh as any process can get reparented to either
PID1 or even any other PID (if there are custom reapers in the system).
Similar issue with jails, elevated process can ask kernel to attach itself into any jail at any time,
thus JID and jail name can change each refresh cycle.

Add OpenBSD signals

FreeBSD
Linux
Other platforms will have it undefined for now.

htop fails to compile with:

```text
SignalsPanel.c:32:49: error: use of undeclared identifier 'Platform_signals'
      Panel_set(this, i, (Object*) ListItem_new(Platform_signals[i].name, Platform_signals[i].number));
                                                ^
1 error generated.
*** Error code 1
```

Implementations for Linux (tested) and FreeBSD (still untested, thanks to @etosan for providing the table).
Darwin and OpenBSD(ping @mmcco) builds should be broken now, pending their own tables.

Cleanup and initial OpenBSD support

add editorconfig file to give hints to editors

We use an unusual indent of three spaces. Let's give editors a hint
about that.

Added preliminary attempt at jails support on FreeBSD - JID and JAIL (name) columns

Added preliminary attempt at jails support on FreeBSD - JID and JAIL (name) columns, somewhat more correct kernel "thread" detection.

Seems FreeBSD kernel can spawn both kernel processes (what is what htop currently sees) and kernel threads.
For now let's consider kernel processes kernel "threads".

Update htop.desktop (FR l10n)

Change more fprintf(stderr, ...); exit(...); to err[x](...). Tweak a few existing ones and fix some style.

fix

Mac build fixes

This one is adding FR localisation to the desktop file.
Cheers.

It's the case on Darwin, and might be in other BSDs as well.
As referred in #268.
Supersedes PR #269.

Darwin fixes - duplicate & conflicting decls
