Change procd_add_start_mount_trigger to procd_add_restart_mount_trigger
and make it call 'restart' instead of 'start'.
This is more useful as it allows to handle both cases, intial start of
a services as well as restarting services. Calling 'restart' on a
service which has not yet been started has the same result as calling
'start'.

e10de28 jail: cgroups-bpf: fix compile with musl 1.2
f5d9b14 hotplug-dispatch: fix rare memory leaks in error paths
Add new init script helpers:
procd_add_start_mount_trigger
procd_add_reload_mount_trigger
procd_get_mountpoints
Both trigger helpers expect a list of paths which are checked against
the mount targets configured in /etc/config/fstab and a trigger for all
mountpoints covered by the list of paths is setup.
procd_get_mountpoints is useful to find out if and which mountpoints
are covered by a list of paths.
Example:
DATADIRS="/mnt/data/foo /mnt/data/bar /etc/foo/baz /var/lib/doe"
start_service() {
[ "$_BOOT" = "1" ] &&
[ "$(procd_get_mountpoints $DATADIRS)" ] && return 0
procd_open_instance
# ...
procd_close_instance
}
boot() {
_BOOT=1 start
}
service_triggers() {
procd_add_start_mount_trigger $DATADIRS
}

Before this commit, it was assumed that mkhash is in the PATH. While
this was fine for the normal build workflow, this led to some issues if
make TOPDIR="$(pwd)" -C "$pkgdir" compile
was called manually. In most of the cases, I just saw warnings like this:
make: Entering directory '/home/.../package/gluon-status-page'
bash: line 1: mkhash: command not found
bash: line 1: mkhash: command not found
bash: line 1: mkhash: command not found
bash: line 1: mkhash: command not found
bash: line 1: mkhash: command not found
bash: line 1: mkhash: command not found
bash: line 1: mkhash: command not found
bash: line 1: mkhash: command not found
[...]
While these were only warnings and the package still compiled sucessfully,
I also observed that some package even fail to build because of this.
After applying this commit, the variable $(MKHASH) is introduced. This
variable points to $(STAGING_DIR_HOST)/bin/mkhash, which is always the
correct path.

Commit 6e060bd62c introduced a dependency to the dialout group.
Adding this group to the "group" file in the base-files package is not
enough to handle this dependency, because after a sysupgrade this entry
will be missing in the "group" file.
To address this problem the dependencies to the required groups needs to
be set in the Makefile of the procd package.
Then, the uci-default script "13_fix_group_user" will add the groups
on first boot-up after a sysupgrade.
