Add the KERNEL_BTRFS_FS config option so that targets can select
whether BTRFS support must be built-in.
Select this option (alongside KERNEL_BTRFS_FS_POSIX_ACL) from the
layerscape/armv8_64b subtarget instead of enabling it in
target/linux/layerscape/armv8_64b/config-* files.
Move disabling of CONFIG_BTRFS_FS_CHECK_INTEGRITY into generic configs.
This makes it possible for OpenWRT to be built with built-in BTRFS
support on specific boards, instead of whole targets.

Commit ec885796c0 switched the crc32 implementation from default to
byte-at-a-time algorithm, which runs slower but consumes less memory.
A decade has passed, and we have already abandoned targets that had
small memory, so switch it back to default for faster speed.

The partition parser approach has been rejected upstream, it will be
replaced by a small block driver which is the solution suggestion by

As the partition parser has only been used by the mediatek target, as
a first step, move it there.

In commit b2d1eb717b ("generic: 5.15: enable Werror by default for
kernel compile") CONFIG_WERROR=y was enabled and all warnings/errors
reported with GCC 12 were fixed.
Keeping this in sync with past/future GCC versions is going to be uphill
battle, so lets introduce new KERNEL_WERROR config option, enable it by
default only for tested/known working combinations and on buildbots.

This allows loading modules with large memory requirements, recently needed
while testing on armvirt/32. Past forum discussions [1] and bug reports [2]
also raised this and the ipq806x target already set it in response [3].
Given this increases kernel image size by only ~1KB, is generally useful on
multi-platform kernels, and enabled by default on upstream arm32 Linux, add
it to the generic config.
The setting has similar utility on arm64, is a requirement for KASLR, and
already enabled on most OpenWrt aarch64 targets, so pull this into the
top-level generic config.

Since CONFIG_DYNAMIC_DEBUG is already managed via the KERNEL_DYNAMIC_DEBUG
setting in Config-kernel.in (default N), remove or disable it in target
configs which unconditionally enable it, along with the related setting
CONFIG_DYNAMIC_DEBUG_CORE. This saves several KB in the kernels for
ipq40xx, ipq806x, filogic, mt7622, qoriq, and sunxi.

This activates the following kernel options by default:
* CONFIG_RANDOM_TRUST_CPU
* CONFIG_RANDOM_TRUST_BOOTLOADER
With these option Linux will also use data from the CPU RNG e.g. RDRAND
and the bootloader to initialize the Linux RNG if such sources are
available.
These random bits are used in addition to the other sources, no other
sources are getting deactivated. I read that the Chacha mixer isn't
vulnerable to injected entropy, so this should not be a problem even if
these sources might inject bad random data.
The Linux kernel suggests to activate both options, Debian also
activates them. This does not increase kernel code size.

"842" is a compression scheme and this is the software implementation
which is too slow to really use beyond a proof of concept. It can be
selected in ZRAM, ZSWAP, or `fs/pstore`, and is here for completeness.
