init: builtins: Update 'setkeycode'

Merge from gingerbread commit f815fcce7dfad2940d22846485478b8e18df4a3c.
Defer kc limit check to the kernel.

init: builtins: Add 'setkeycode' command to init.rc parser

The command is used to set an entry into the kernel's scancode-to-keycode map.

init: set debug.logcat according to DEBUG variable

init: disable hardware specific gralloc

To disable 3D hardware acceleration totally, we need to
tell HAL not to load hardware specific gralloc library.

This is just a workaround. In the future we should implement a
gralloc wrapper to detect graphic driver and load the appropriate
gralloc library.

Merge branch 'mksh' into froyo-x86

init: add an option to disable 3D hardware acceleration

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

add back libdiskconfig_host

This is required by editdisklbl on building usb_img target.

libsysutils: reimplement NetlinkEvent::findParam in the proper 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 "=".

init: change FIRMWARE_DIR for x86

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

add ppp scripts for 3G internet connection

init: set proper permissions for /dev/ttyUSB*

do not include goldfish files on x86

init: a hack to avoid kernel warning

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

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

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.

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

init: Create subdirectory for drm subsystem.

Update mksh to CVS 2010/09/19

* code cleanups (whitespace, int->bool, prototypes)
* add cat as a builtin
* reduce size by string pooling
* optimise error messages and option parsing
* make more builtins honour "--" as argument separator
* check integer operations that may overflow, as well as
setres{u,g}id/setuid which can throw EAGAIN on Linux;
thanks to Chris Palmer for pointing those out
* reduce size by removing a shell (set -o) flag that is
deprecated anyway and was never usable in Android, and
removing RCS IDs from the code

Don't alias 'stop' to 'kill -STOP'

Android has already has a stop command used
to stop the main runtime and the alias
interferes with testing tools that expect
stop to kill the runtime.

Add mksh from CVS 2010/08/24 as system/core/mksh module

Both shells (ash from system/core/sh, and mksh) are built by
default but only the one where $(TARGET_SHELL) is set to is
actually installed (the shell and the mkshrc configuration
file are tagged shell_mksh for this to work).

Make /proc/kmsg and /proc/sysrq-trigger system-process-readable

This is so that the system process can capture kernel thread stacks when the
watchdog detects a deadlock. Previously, /proc/kmsg was root/root and mode
0400, and /proc/sysrq-trigger was root/root and mode 0200. With this
change, /proc/kmsg becomes root/system and 0440, and /proc/sysrq-trigger
becomes root/system and 0220.

More fixes to Binder perf regression from Eclair

Re-use the file descriptor to change the cgroups. There's a fast path
in the kernel for the case where the value's already uncahnged. Also,
this is okay because the kernel ignores the write offset. This is
essentially a ioctl-ish/datagram interface, despite being a fd we're
writing to.

This reduces Dalvik->Dalvik void/void Binder calls on Sapphire from
~1.2 to ~0.8 ms. This is a bit slower than the ~0.7 ms we get
avoiding the write altogether.

strace confirms:

[pid 1557] ioctl(21, 0xc0186201 <unfinished ...>
[pid 1556] <... ioctl resumed> , 0x45399cd0) = 0

Optimize set_sched_policy(), which gets called in every binder call.

- use static /dev/cpuctl filenames, rather than sprintf() on the fly
- use a custom formatter instead of sprintf() for the tid number
