Add quiet_genkernel to make quieter boot.

The kernel boot option 'quiet' makes both the kernel & genkernel boot
quietly.

The new kernel boot option 'quiet_genkernel' just makes genkernel boot
quietly, while not affecting the kernel verbosity.

initrd.scripts: prompt_user(): Read answer from $GK_PROMPT_FILE on timeout

This commit will bring back read timeout which was removed in
Commit a280829. Read timeout is still disabled by default but
can now be controlled via gk.prompt.timeout kernel command-line
argument.

When gk.prompt.timeout is != 0, the current prompt will be written
to $GK_PROMPT_FILE. This will allow remote user to notice that
there's a prompt.

In addition, on timeout, $GK_PROMPT_FILE will be read allowing
remote user to answer prompt and hopefully to fix the problem
and resume booting.

To make this work, gk.prompt.timeout will be set to 30 seconds
by default when SSH usage is enabled.

linuxrc: Log initramfs output/commands

By default, any {bad,good,warn}_msg output and external command calls
will now be logged to /tmp/init.log in initramfs. This can be turned
off via gk.log.disabled={1,yes} kernel command-line argument.

This is especially helpful when working with remote servers when you
can access initramfs system through SSH.

In addition, initramfs' log file can be preserved, i.e. copied to
real system just before switch_root call. This can be controlled
via gk.log.keep kernel command-line argument: When just enabled,
initramfs will copy log to $NEWROOT/genkernel-boot.log. Keep in my
that the file path must be accessible for initramfs and by default,
initramfs will only mount / as $NEWROOT and no additional mountpoints.

initrd.scripts: modules_load() refactored

- Add support for LABEL/UUID in root kernel parameter

- When loading network, always load all network modules
  even when root block device is already available

- Always load crypto and USB module group when CRYPT_{ROOT,SWAP}
  is set.

- Always load fs module group.

- Add gk.hw.load-all kernel command-line argument to allow
  user to force loading of all module groups.

linuxrc: Add gk.userinteraction.disabled

When this option is set and enabled, genkernel initramfs will not prompt
on errors, i.e. this will disable any user interaction, e.g. for a kiosk system.

defaults/linuxrc: Disable processing of modules_load file by default

Now that we are using (e)udev with kmod support, we can rely on UDEV to
load required kernel modules.

Old module loading based on modules_load file can still be enabled via
boolean "gk.hw.use-modules_load" kernel command-line option which is inverting
and replacing previous "nodetect" kernel command-line option.

defaults/linuxrc: Add gk.udev.debug to run udevd in debug mode

When gk.udev.debug=yes is set (boolean option), udevd will run in
debug mode. Output will be written to /run/initramfs/udevd.log.

We need to do the same we do for rootfs since commit 05f968fda2c6839744b36c442b3feaa6de974e63
also for {root,swap}_keydev.

linuxrc: add kernel command-line argument to allow user to pass additional options to cryptsetup

Cryptsetup supports additional options like "--perf-no_read_workqueue" or
"--perf-no_write_workqueue". While it is recommended to use LUKS2 format
and make these activiation flags permanent, you can also make use of
the new kernel command-line arguments "crypt_root_options" for root device
or "crypt_swap_options" for swap device to pass additional options
to cryptsetup.

These arguments can be specified multiple times or separate multiple
options with a comma.
