We only support creating initramfs nowdays, so RAM disk support is not needed.
Since initramfs does not need root=/dev/ram0 (and we actually ignore it if it is set),
we should not tell people to use it.
We should also stop tell people to use real_root.

Somewhere in the mists of time we lost part of the multipath patch, so
we were bundling the userspace, but not the kernel modules, or ever
using it.

When using an integrated initramfs (including in kernel during build),
it's better NOT to compress the initramfs, as the kernel build process
will then be re-compressing it. This can provide space savings on disk
as well as potential time & memory savings (one less decompress pass is
needed before the kernel can use the initramfs).
This functionality was previously available in the undocumented
COMPRESS_INITRD variable.

(commit message rewritten).
Provide real boolean commandline options for options that were
previously only available as booleans in the config, so that they can be
enable in configuration and overridden to disable on the commandline.
Remove negation on options: NOINSTALL, NORAMDISKMODULES,
NO_KERNEL_SOURCES.

Make it possible to choose a custom mdadm.conf for your ramdisk.
If not set, no mdadm.conf will be copied, and ramdisk will auto-detect.
This also fixes a regression where genkernel always tried to copy
/etc/mdadm.conf to the ramdisk, failing if it was non-existant.
