Fix ask_for_password bug breaking bash without plymouth
If crypt-lib.sh is sourced from any #!/bin/sh script, a POSIX shell
quirk is in effect that causes variable assignments to "special
builtins" (such as "shift") to leak to their context. So the buggy
code works even despite the missing semicolons.
But if it is sourced by "bash acting under its own name", i.e. from
any #!/bin/bash script, the quirk is disabled, tty_cmd/tty_prompt are
undefined, and ask_for_password doesn't do anything if plymouth is not
present.

drm/module-setup.sh: radeon needs amdkfd
AMD's HSA Linux kernel driver (amdkfd) has been merged into the mainline
kernel since kernel 3.19.
However, for the driver to work, it needs to be included in the default
initramfs image, together with the amd_iommu_v2 driver.
The radeon driver (AMD's kernel graphic driver) calls amdkfd during its
initialization and probing stages. Because radeon is included in the
initramfs image, it tries to initialize amdkfd during the early boot
stages. However, as amdkfd is not present there, it fails.
That doesn't harm radeon operation. However, it disables the HSA
abilities in the machine.
Because of the current design, if you later try to "modprobe amdkfd",
you won't be able to run HSA applications, even though the driver will
be loaded.

Add support for ethernet point-to-point connections configured via DHCP
When current dracut receives an ip with netmask of 255.255.255.255 via DHCP,
setting the also supplied default gateway fails (because it is obviously not
within the netmask).
The setup with a netmask of /32 is quite common in colocation datacenters
where you don't want the machines of two different customers to directly talk
to each other. At least two of the biggest colocation providers in Germany
(1&1 and Strato) do it that way. NetworkManager supports this kind of setup
and the dhclient-scripts of several distributions too.
In this patch I have implemented a simple approach very similar to what is
found in Debian. The dhclient-script from Fedora uses a more sophisticated
approach, but that relies on the ipcalc utility which would introduce a
dependency on Fedora-initscripts for dracut.

crypt-loop: Always include 'loop' kernel module
When the 'loop' kernel module isn't loaded in a running system, it gets
excluded from the hostonly initrd. Given that the crypt-loop dracut
module has to be loaded explicitly anyway, it makes sense to always
include the requisite loop kernel module.

crypt-loop: Fix decrypt when running at info log level
When booting with 'rd.info', the 'info' statements in the crypt-loop
module's 'loop_decrypt' function are output to stdout along with the key
that gets piped into the 'cryptsetup' command, which causes the crypt
device unlocking to fail.
There are two possible simple solutions to this problem:
1. Redirect the info messages to stderr (just add '>&2' at the end of
the info statements).
or
2. Remove the info statements altogether.
I have tested both and they both work, but this commit implements #2.
The existing info messages are long (they overflow 80 characters
easily) and redundant (the password prompt clearly indicates what is
happening), and just generally not useful. Given that no one has
reported or fixed this bug in the three years that this module has
existed, no one will miss these info messages.
The commit also changes an error message in the same function to be more
descriptive.

dmsquash: Add squashfs support to rd.live.fsimg
Previously rd.live.fsimg only supported filesystems residing in

Now rd.live.fsimg can also be used when a squashfs image is used.
This is achieved by extracting the rootfs image from the squashfs and
then continue with the default routines for rd.live.fsimg.
In addition some code duplication got removed and some documentation
got added.

This option changes the underlying mechanism for the overlay in the

Instead of a plain dm snapshot a dm thin snapshot is used. The advantage
of the thin snapshot is, that the TRIM command is recognized, which
means that at runtime, only the occupied blocks will be claimed from
memory, and freed blocks will really be freed in ram.

99base: Properly remove files with rd.hostonly=0
Dracut will generate systemd units for additional devices that should be
brought up during boot, e.g. swap devices. These unit files are broken
symlinks with \ in the filename, e.g.
/etc/systemd/system/initrd.target.wants/dev-disk-by\x2duuid-e6a54f99\x2da4fd\x2d4931\x2da956\x2d1c642bcfee5e.device.
Both the backslash and the broken symlink causes problems for shell
scripts, [ -e "$file" ] isn't enough and read requires the additional -r
argument to not react on the \.
The function 99shutdown/shutdown.sh:_check_shutdown() assumes that
shutdown scripts report success or failure via their return value.
However, "dmsetup remove_all" always reports success, even if some
of the device mappings could not be removed.
I submitted a patch for dmsetup but the lvm2 folks rejected it,
asserting that its behaviour is correct, that "remove_all" should
only be used by developers and that the proper solution would be
to invoke "dmsetup remove" on each device. This does report success
or failure via the return value.
Apart from fixing that issue, this commit also adds the dmsetup
option "--noudevsync". Without it, dmsetup would hang after removal
of a device while trying to communicate with systemd-udevd, which
is no longer running at this shutdown stage.

kernel-modules: increase SDHCI driver inclusion
The sdhci-pci module is currently not being included in the initramfs,
even though other sdhci modules are. This breaks boot on systems that
rely on this driver to access the root filesystem.
Instead of looking for modules that use sdhci_pltfm_init, look for
sdhci_add_host. I checked 3.18 kernel sources, and this change
does not remove any of the previously-matched SDHCI drivers.
It should result in the addition of sdhci-pci, sdhci-s3c, sdhci-spear
and sdhci-acpi.
