init: change FIRMWARE_DIR for x86

On Android-x86, the firmware directory is /system/lib/firmware.

Replace ash with mksh

Squashed commit for easier merging/testing.
Original commit messages before squashing follow below.

Further changes after squashing:
• updated mksh to Easter 2010 weekend (2010/04/05) version
• removed no longer compiled code from adb
• updated mksh to R39 2010/04/09 (extensively tested in Debian)

‣ This is a combination of 19 commits.
‣ The first commit's message is:
Import mksh-current as of 2010/01/12

Retrieved from: cvs -qd _anoncvs@anoncvs.mirbsd.org:/cvs co -PA mksh
Removed: Makefile, CVS/

This code is NOT A CONTRIBUTION, it shall be handled as an external
source. The licence it is under is suitable for Android; it is BSD-
like and contains an explicit copyright grant, and I know of no pa-
tents covering a shell.

‣ This is the 2nd commit message:

Remove NetBSD® ash

‣ This is the 3rd commit message:

Import printf.c from MirBSD

Retrieved via:
cvs -qd _anoncvs@anoncvs.mirbsd.org:/cvs co -PA \
src/usr.bin/printf/printf.c

This is derived from the original BSD source code and slightly
adapted to work well as optional mksh builtin.

‣ This is the 4th commit message:

Add arc4random_pushb implementation for Android

Retrieved from:
cvs -qd _anoncvs@anoncvs.mirbsd.org:/cvs co -PA \
contrib/hosted/tg/arc4rootdom.c

This is code written by me specifically for Android
and starts the series of commits that ARE contributions.

‣ This is the 5th commit message:

Add module licence and summary of legal notices of code actually compiled.

‣ This is the 6th commit message:

Add script used in (manually) creating/adjusting Android.mk

‣ This is the 7th commit message:

And finally, the (hopefully working) Android.mk file for mksh as sh

‣ This is the 8th commit message:

Now that we have mksh, nuke that ugly SH_HISTORY hack.

‣ This is the 9th commit message:

shlist.c is no longer needed without -DSH_HISTORY

‣ This is the 10th commit message:

Get rid of floating point operations.

This was only needed for the (optional) printf(1) builtin,
and the shell shouldn't ever need floating point...
besides, it will work better without in thumb mode.

‣ This is the 11th commit message:

Update printf.c from MirBSD-current

‣ This is the 12th commit message:

Update to mksh R39b (release)

R39b was released today; since the snapshot I initially began
working on is close enough, the build system requires no fur-
ther changes.

The source code is still unmodified from upstream.

‣ This is the 13th commit message:

Upgrade to mksh R39c (release)

‣ This is the 14th commit message:

remove -fstack-protector-all from CFLAGS, it breaks at least on Android-x86

‣ This is the 15th commit message:

add symlink /system/bin/mksh -> /system/bin/sh

‣ This is the 16th commit message:

Disable the mknod(8) builtin for space reasons

‣ This is the 17th commit message:

Upgrade to mksh-current as of 27.03.2010 21:44 UTC

Also, get rid of the NDK and mksh-small part of Android.mk and NOTICE;
we only build the full-features one now, which is tested on Android-x86.

‣ This is the 18th commit message:

Set the MKSH_DEFAULT_EXECSHELL to /system/bin/sh to unbreak “adb install”…

… and any other places that call a script without a shebang.
Discovered and solution suggested by: Chih-Wei Huang <cwhuang@android-x86.org>

‣ This is the 19th commit message:

Add minimal MKSHRC_PATH=/system/etc/mkshrc file for Android ($PS1, …)

init: a hack to avoid kernel warning

Change options androidboot.* to androidboot_* so kernel won't warn it.

vold: rfkill bootstrapping

Simulate rfkill add uevents to change permission of bluetooth devices on boot.
This is better since it works after suspend and wakeup.

vold: usb drive bootstrapping

The usb drive plugged before booting can be mounted by this change.

init: add an option to disable 3D acceleration

If the hardware OpenGL support doesn't work for you,
disable it by adding HWACCEL=0 to cmdline.

init: Create subdirectory for drm subsystem.

fixed a bug caused by the changes in the prop name size

add etherenet state tracker support.

The dhcpcd somehow can not handle multiple interfaces with on command line.
I have to create different services for different interfaces

fix permission of /dev/videoX, and remove unnecessary /dev/snd/*

patch from Yi Sun to fix power status issue

vold: add fat partition type detection, and fix a crash bug

vold: auto-mount MMC/SD and USB drive

Based on Yi Sun's work: add vold support on usb drive

vold: validate fw_sock before trying FD_ISSET it

vold: reimplement get_uevent_param in the correct way

The original implementation can not find correct parameters for certain
cases. For example, if you have both foo_bar and foo, try to find foo
may be mismatched. The correct way is to match with "=".

Modify from original patch of Yi Sun.

Let console applications have a controlling tty.

Since the logic in open_console() is changed, terminating console
application within a shell is now possible via Ctrl-C.

Define HAVE_SYS_SENDFILE_H.

Platforms differ on whether sys/sendfile.h or sys/socket.h is where to
find the declaration for sendfile().

Make get_my_path() safer

Adds maxLen parameter to get_my_path().
Some small cosmetic fixes.

libsysutils: Fix some bugs in NetlinkListener and NetlinkEvent

Set permissions properly for any ALSA device under /dev/snd

Allow an onrestart command to stop the current service

For example,

service recovery /sbin/recovery
onrestart start loadkeys
onrestart class_start con
onrestart stop recovery

Previously, if you had a service like the above, the "onrestart stop
recovery" clause would not have any effect, because the restart flag
would be re-set after the stop command had executed.

This is similar to a service with the "oneshot" keyword, with the critical
difference being that it executes the other onrestart commands when the
service dies.

added chdir/chroot commands to init for mount switching/pivoting

Trivial implementation of init's import command.

completed implementation of "trigger" for init

Fix incorrect check for LOG_UEVENTS

LOG_UEVENTS is a boolean value as defined in system/core/init/init.h.
Therefore, code should use an #if check and not an #ifdef check as the
macro will always be defined.

init.rc: Fixes typo: sytem -> system.

Fix bug of mmc.c not checking read_file result.
This bug causes segment fault when reading name node of
SDIO mmc device's /sys file, which is not existed at all.
