mDNS broadcast can't accept empty TXT record and would fail
registration.
Current procd_add_mdns_service checks only if the first passed arg is
empty but don't make any verification on the other args permittins
insertion of empty values in TXT record.
Example:
procd_add_mdns "blah" \
"tcp" "50" \
"1" \
"" \
"3"
Produce:
{ "blah_50": { "service": "_blah._tcp.local", "port": 50, "txt": [ "1", "", "3" ] } }
The middle empty TXT record should never be included as it's empty.
This can happen with scripts that make fragile parsing and include
variables even if they are empty.
Prevent this and make the TXT record more solid by checking every
provided TXT record and include only the non-empty ones.
The fixed JSON is the following:
{ "blah_50": { "service": "_blah._tcp.local", "port": 50, "txt": [ "1", "3" ] } }

Different from OPKG, APK uses a deterministic version schema which chips
the version into chunks and compares them individually. This enforces a
certain schema which was previously entirely flexible.
- Releases are added at the very and end prefixed with an `r` like
`1.2.3-r3`.
- Hashes are prefixed with a `~` like `1.2.3~abc123`.
- Dates become semantic versions, like `2024.04.01`
- Extra tags are possible like `_git`, `_alpha` and more.

The existing implementation incorrectly reported `running` for services
without any instances or with all instances stopped/terminated.
Improve the default implementation of `/etc/init.d/* status` to properly
report services with not running instances. In case a service exists,
but without running instance, the status call will now report
"not running" with exit code 5. In case some instances are running and
some are stopped/terminated, the call will report "running (X/Y)" where
`X` denoted the amount of running instances and `Y` the amount of total
registered ones.

This reduces open coding and allows to easily add a knob to enable
it treewide, where chosen packages can still opt-out via "no-lto".
Some packages used LTO, but not the linker plugin. This unifies 'em
all to attempt to produce better code.
Quoting man gcc(1):
"This improves the quality of optimization by exposing more code to the
link-time optimizer."
Also use -flto=auto instead of -flto=jobserver, as it's not guaranteed
that every buildsystem uses +$(MAKE) correctly.

The /tmp directory is mounted as tmpfs. The tmpfs filesystem is backed by
anonymous memory, which means it can be swapped out at any time, if there is
memory pressure [1]. For this reason, a zram swap device is a much better
choice than mounting /tmp on zram, since it's able to compress all anonymous
memory, and not just the memory assigned to /tmp. We already have the zram-swap
package for this specific purpose, which means procd's tmp-on-zram is both
redundant and more limited.
A follow-up patch will remove support for mounting /tmp in zram from procd
itself.

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.

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

'start'.

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
