procd: seccomp/jail: Fix build error on arm with glibc
From: Peter Lundkvist <peter.lundkvist@gmail.com>

This fixes the make_syscall_h.sh script to recognize both
__NR_Linux, used by mips, and __NR_SYSCALL_BASE and
__ARM_NR_BASE used by arm.

Run-tested on arm (ipq806x) and mips (ath79), both with glibc.
Compile-tested and checked resulting syscall_names.h file wuth
glibc: aarch64, powerpc, x86_64, i486
musl: arm, mips

Fixes: FS#4194, FS#4195

buildsystem: add CONFIG_SECCOMP
Until now, this feature was switched on via the kernel configuration
option KERNEL_SECCOMP.

The follwing change a7f794cd2a now requires that
the package procd-seccomp must also enabled for buildinmg.

However, this is not the case we have no dependency and the imagebuilder
cannot build the image, because of the implicit package selection.

This change adds a new configuration option CONFIG_SECCOMP.
The new option  has the same behaviour as the configuration
option CONFIG_SELINUX.

If the CONFIG_SECCOMP is selected then the package procd-seccomp and
KERNEL_SECCOMP is enabled for this build.

procd: change procd_add_start_mount_trigger to do restart
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'.

procd: update to git HEAD and add new script helpers
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
  }

b993b68b6c build: introduce $(MKHASH)
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.
