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.

Generate BTF (BPF Type Format) information from DWARF debug info. This is
embedded in the kernel and exported via sysfs as /sys/kernel/btf/vmlinux.
BTF data enhances kernel portability and introspection for BPF programs.
Selecting this also enables the dwarves host package which provides the
pahole tool used for BTF encoding.
Test using: "bpftool btf dump file /sys/kernel/btf/vmlinux format c"

No package here depends on it. Furthermore, uClibc++ is a fairly buggy
C++ library and seems to be relatively inactive upstream.
It also lacks proper support for modern C++11 features.
The main benefit of it is size: 66.6 KB vs 287.3 KB on mips24kc. Static
linking and LTO can help bring the size down of packages that need it.

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.

In OpenWrt, /var is symlinked to /tmp by default. This is done to reduce
the amount of writes to the flash chip, which often have not the
greatest durability. As a result, things like DHCP or UPnP lease files,
are not persistent across reboots.
Since OpenWrt can run on devices with more durable storage, it makes
sense to have an option for a persistent /var. Add an option to make
/var persistent. When enabled, /var will no longer be symlinked to /tmp,
but /var/run will be symlink to /tmp/run, as it should contains only
files that should not be kept during reboot. The option is off by
default, to maintain the current behaviour.

Instead of embedding the initrd cpio archive into the kernel, allow
for having an external ramdisk added to the FIT or uImage.
This is useful to overcome kernel size limitations present in many
stock bootloaders, as the ramdisk is then loaded seperately and doesn't
add to the kernel size. Hence we can have larger ramdisks to host ie.
installers with all binaries to flash included (or a web-based
firmware selector).
In terms of performance and total size the differences are neglectible.
