This adds support for sysupgrade on ONIE-installed systems.
The install is chained through ONIE (using the ONIE installer image),
rather than attempting to manually upgrade the partition.
The idea is to allow future OpenWRT installs flexibility to use
a different partition table. By putting the installer in charge
of setting up the file system partition, the upgrade process needs
to have no knowledge of the internals of the image.
Config preservation is accomplished by appending the sysupgrade .tar.gz
to the ONIE installer image. Of course this also works for a clean
install using a sysupgrade.tar.gz created via `sysupgrade -b`.

The current documentation for using OpenWRT on Mellanox Spectrum
switches (https://openwrt.org/toh/mellanox/spectrum) suggests
reflashing the entire harddrive from the recovery USB. This is not
the most friendly way to install a new OS on these switches. From
factory, they come with ONIE (Open Network Install Environment),
which is a linux-based preboot environment for fetching an OS
image from the network and installing it on disk. The installer
is a self-executing bash script that executes inside the ONIE
environment. The installer is expected to preserve the ONIE partition
for use as recovery environement. To be a better citizen on
these platforms, it would be preferrable to provide OpenWRT as
an ONIE-compatible installer.
This PR adds an ONIE_INSTALLER_IMAGES build option that produces
an ONIE compatible .bin. The generated .bin follows the ONIE demo
installer pattern [1]: it creates a new GPT partition
labelled OPENWRT-ROOT on the ONIE install device, formats ext4, extracts
the OpenWrt rootfs and kernel into it, installs GRUB into the existing
UEFI ESP under bootloader-id "OpenWrt", and adds a NVRAM boot entry via
efibootmgr. ONIE-BOOT is preserved so ONIE rescue remains available.
Tested with the config at [2] on a Mellanox Spectrum SN3800 to produce
a booting OpenWRT install.

Add KERNEL_NR_CPUS option in Global build settings → Kernel build
options, allowing users to set maximum CPU count (2-512) for the image.
Defaults:
- x86_64: 512 CPUs (backward compatible)
- x86: 8 CPUs (fix broken single-CPU default)
Per-CPU data structures consume ~100-200KB each.
On a 4-core system configured to NR_CPUS=4, this frees approx 76 MB
of RAM: (512 - 4) × 150 KB = ~76 MB
Note: CONFIG_NR_CPUS_RANGE_{BEGIN,END}= and CONFIG_NR_CPUS_DEFAULT= are
set by the build system and will default to 2/512/64 per arch/x86/Kconfig
These are harmless metadata and don't affect memory allocation.

Add a build config option to sign each individual .apk package.
If individual .apk files are signed with the build key, they can be
installed with 'apk add' without '--allow-untrusted' to a firmware
compiled by the same buildhost.
Enable the option by default, but disable it for BUILDBOT.
(At the moment, since commit 084697e, only the package index is signed,
which forces users to use '--allow-untrusted' when installing
self-built .apk files.)

This adds the -Wl,-z,pack-relative-relocs linking options.
This reduces the size of some binaries.
This is only supported on i386, x86_64, aarch64 and loongarch64 in
binutils. This feature is not support for MIPS.
musl libc supports it since version 1.2.4 .
glibc supports it since vesion 2.36.
binutils ld supports it since version 2.38 for x86 and since version
2.43 for LoongArch.
This reduces the size of the armsr default root file system from

PSI provides a canonical way to see resource pressure increases as
they develop, with pressure metrics for three major resources:
memory, CPU, and IO. PSI stats are like barometers that provide
fair warning of impending resource shortages, enabling users to

start becoming scarce.

It seems that we have some kind of a symbol name conflict which causes
CONFIG_SECCOMP to always be read as y.
Unfortunatelly, I could not figure out what is causing this, but simply
renaming SECCOMP to USE_SECCOMP seems to properly work and leaves the
symbol unset unless arch dependencies are satisfied.
This fixes qoriq and others that dont support seccomp from failing due
to procd-seccomp package being selected to get included but it cannot be

Expose Kernel's CONFIG_MPTCP option and enable it by default for
!SMALL_FLASH targets.
The idea behind enabling it by default is to allow users of the binary
distribution to make use of MPTCP tunneling for link aggregation.
Using MPTCP for link aggregation is an often discussed topic in the
forum and there is even a whole OpenWrt fork (MPTCPRouter) just for that.
Enabling the kernel-side of the story by default will allow using MPTCP
on vanilla OpenWrt without having to build anything from source.
