When kbuild is using a separate directory for output files then it will
check if the kernel source directory is clean.
The build will throw an error when the source directory is not clean:
.. is not clean, please run 'make mrproper'
Once envkernel.sh has aliased the make command then make mrproper will
be run in the context of .output directory. If the source directory is not
clean then user may be wondering why make mrproper doesn't clean it.
This change will ensure that the source directory is clean when envkernel
is setup.
The pmbootstrap alias cannot be used within the script.
The reason is that aliases are not expanded in non-interactive shells.

To fix this replace references to the pmbootstrap alias with
the $pmbootstrap variable
* change "pmbootstrap kconfig_check" to "pmbootstrap kconfig check"
* change "pmbootstrap menuconfig" to "pmbootstrap kconfig edit [-x|-g]"
(with legacy alias, because the first syntax was referenced to a lot)
* enable X11 interfaces: -x: xconfig, -g: gconfig
* new function to copy the xauthority file:
pmb.chroot.other.copy_xauthority()
* remove menufconfig() function from the kernel template and all kernel
aports ([skip ci] because it would rebuild all kernels and run out of
time). Alpine has dropped this as well, and it wouldn't work with the
new code anyway.
Changes:
* `helpers/envkernel.sh`:
* installs everything needed for kernel compilation in the native
chroot
* mounts the kernel source to `/mnt/linux` inside the chroot
* creates `/mnt/linux/.output` and chowns it to the `pmos` user, that
folder will be used for the kernel build output
* sets up aliases for `make`, `pmbootstrap`, `pmbroot`, `kernelroot`
* new action `pmbootstrap work_migrate`: does the interactive work
folder migration if necessary, otherwise it doesn't output anything
* when calling this first, we can safely use all other commands
non-interactively without showing the output
Benefits:
* Fast setup (especially for people who are new to kernel
compilation
* No need to figure out distribution specific package names
(cross compilers!)
* No need to do a test build just to verify that the right
packages are installed
* Less error prone
* The right dependencies are always installed
* `ARCH` and `CROSS_COMPILE` variables always get set automatically
and based on `deviceinfo_arch`
* If the build environment is broken for some reason, just zap and
start over
* Easy to reproduce problems
Notes:
* `make menuconfig` works as well
* Sourcing was tested with `zsh`, `bash` and `fish`, it should be easy to
extend for other shells
* Change `pmbootstrap flasher flash_system` command to
`pmbootstrap flasher flash_rootfs`
* The old command still works, but all references have been changed to
the new command
* Remove obsolete `pmbootstrap flasher export` (that was changed to
`pmbootstrap export` a few months ago)
* Update `README.md` and ZSH auto completion
* Change the description of the generated rootfs image (not talking
about a system image anymore, mention that it has subpartitions)
* Better description of `pmbootstrap flasher flash_rootfs --partition`
