This implements customizable initramfs compression, based on the Pentoo
genkernel fork (SVN revs r2142, r2145, by Jens Pranaitis
<jens@chaox.net>).
New configuration option COMPRESS_INITRD_TYPE to allow manual selection,
whereas the Pentoo fork provided auto-selection based on what was
available in the kernel configuration. Auto-selection is used by
default, and is available with the argument of 'best' to the new option.

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.
Add INTEGRATED_INITRAMFS option to optionally insert the generated initramfs directly into the kernel image
Change default build order to build the kernel last to facilitate the INTEGRATED_INITRAMFS option
Add GENZIMAGE option and change various checks from ENABLE_PEGASOS_HACKS to GENZIMAGE
