BTF mismatch can occur for a separately-built module even when the ABI
is otherwise compatible and nothing else would prevent successfully
loading. Add a new config to control how mismatches are handled. By
default, preserve the current behavior of refusing to load the
module. If MODULE_ALLOW_BTF_MISMATCH is enabled, load the module but
ignore its BTF information.

We only use 5.15 kernel. So remove all those unnecessary symbols
referencing 5.10 or 5.15 kernel.
Can be found with:
git grep -E 'LINUX_5_1(0|5)'
Note that we remove the dependency from "sound-soc-chipdip-dac" instead
of removing the complete kernel package. The 5.15 version bump forgot to
delete the "@LINUX_5_10" dependency. The kernel package is still needed
in 5.15 kernel.

Kernel setting CONFIG_IO_URING supports high-performance I/O for file
access and servers, generally for more performant platforms, and adds
~45 KB to kernel sizes. The need for this on less "beefy" devices is
questionable, as is the size cost considering many platforms have kernel
size limits which require tricky repartitioning if outgrown. The size
cost is also large relative to the ~180 KB bump expected between major
OpenWRT kernel releases.
No OpenWrt packages have hard dependencies on this; samba4 and mariadb
can take advantage if available (+KERNEL_IO_URING:liburing) but
otherwise build and work fine.
Since CONFIG_IO_URING is already managed via the KERNEL_IO_URING setting
in Config-kernel.in (default Y), remove it from those target configs
which unconditionally enable it, and update the defaults to enable it
conditionally only on more powerful 64-bit x86 and arm devices. It may
still be manually enabled as needed for high-performance custom builds.

Set default values for KERNEL_DEBUG_LL and KERNEL_DEBUG_LL_UART_NONE again
as both of these symbols are non visible if KERNEL_EARLY_PRINTK is not
selected and KConfig wont write their value to .config.
This usually is the intended behaviour, but in OpenWrt we are relying on
the KConfig to set these and disable the debug console settings that
multiple targets like mvebu have set in their kernel config.
This was the behaviour before removing all of the "default n" settings
as KConfig by default considers symbols disabled but they are not visible
anymore and thus their value is not set in .config and build system then
later does not override the values from target kernel config.
So, to restore the behaviour to the previous one lets a default value for
KERNEL_DEBUG_LL and KERNEL_DEBUG_LL_UART_NONE.

Introduce a new option in the "Advanced configuration options" to
configure a custom download tool.
By declaring a string in "Use custom download tool" an user can force
what command to use to download package. With the string empty the
default tool used is curl, with wget as a fallback if not available.
download.pl supports 3 tools officially aria2c, curl and wget.
If one of the tool is used in this config, download.pl will use the
default args to make use of them.
If the provided string is different than aria2c, curl or wget, the command
is used as is and the download url will be appended at the end of such command.
While at it also tweak the tool selection logic and chose the tool only
once when the script is called and move aria2c specific variables in the
relevant section.
