Since now we support both kernel 4.19 and 5.2, change the
condition to remove driver when on kernel 4.14

The current implementation is significantly lowering lantiq
performace [1][2] by using RPS with non-irq CPUs and XPS
with alternating CPUs.
The previous netifd implementation (by default but could be
configured) simply used all CPUs and this patch essentially
reverts to this behaviour.
The only document suggesting using non-interrupt CPUs is Red
Hat [3] where if the network interrupt rate is extremely high
excluding the CPU that handles network interrupts *may* also
improve performance.
The original packet steering patches [4] advise that optimal
settings for the CPU mask seems to depend on architectures
and cache hierarcy so one size does not fit all. It also
advises that the overhead in processing for a lightly loaded
server can cause performance degradation.
Ideally, proper IRQ balancing is a better option with
the irqbalance daemon or manually.
The kernel does not enable packet steering by default, so
also disable in OpenWRT by default. (Though mvebu with its
hardware scheduling issues [5] might want to enable packet
steering by default.)
Change undocumented "default_ps" parameter to clearer
"packet_steering" parameter. The old parameter was only ever
set in target/linux/mediatek/base-files/etc/uci-defaults/99-net-ps
and matched the default.

Currently bootloader always stays on the same version as when first
written to boot medium (not true if partition layout changed, which will
trigger sysupgrade process to write full disk image). That creates
inconveniences as it always stays with same features or/and bugs. Users
wishing to add support to additional modules or new version, would need
to write the whole image, potentially destroying previous system
configuration. To fix these, this commit adds additional routine to
sysupgrade which upgrades unconditionally the bootloader to the latest
state provided by OpenWrt.

The BUILD_VARIANT might differ from UBOOT_CONFIG, so point to a file we
are actually changing. Being here let's call 'Build/Configure/U-Boot'
definition, instead of definig the same command. This'll be more future
proof, if U-Boot configuration procedure will change.

Because /etc/profile (and ~/.profile) are read by login shells only,
aliases and functions defined there are not available to non-login
shells, e.g. when using screen or tmux.
If the ENV environment variable exists (exported by /etc/profile or
~/.profile) and references an existing file, then all interactive shells
(login or non-login) will read that file as well.
This sets the ENV environment variable in /etc/profile, pointing to
/etc/shinit.
This also adds /etc/shinit, which:
* Contains alias and function definitions originally in /etc/profile
* Sources /etc/mkshrc if the user is using mksh (also originally in
/etc/profile), as /etc/mkshrc is meant for all interactive shells
* Sources ~/.mkshrc if the user is using mksh, to compensate for the
fact that mksh will not read ~/.mkshrc if ENV is set
* Sources ~/.shinit if the user is not using mksh
This also removes the shebang from /etc/profile, as the file is sourced,
not executed.

This activates PIE ASLR support by default when the regular option is
selected. This is required to enable PIE ASLR support by default in ppp,
as it fails to build without it, on x86/64.
The .so file size stays identical.
