More fixes to Binder perf regression from Eclair
Instead of allocating memory from the (non executable) heap,
allocate memory using mspace and ensure that we use mprotect
to mark it as PROT_EXEC. This allows pixelflinger to
continue to work even when NX protections are enabled.
Testing: Using the ApiDemos market app, verify that
Apidemos -> Graphics -> OpenGL ES -> GLSurfaceView
works when "adb shell setprop debug.egl.hw 0" is set.

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.

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

cpu-features.h is only available for ARM
The Pixelflinger disassembler does not handle LDM addressing modes correctly,
assuming that the P and U bits in the instruction mean the same in both LDM and
STM. This results in the disassembler producing sequences like:
stmfd r13!, {r4-r11, r14}
...
...
...
ldmea r13!, {r4-r11, r14}
This small patch fixes it by EORing the P and U bits with the Load/Store bit.

Fixing spelling errors in adb docs
Make adb's daemon-port on the host machine configurable.
adb: remove obsolete adb.connected system property.
Add Pantech's USB vendor ID to adb.
Added Kyocera's VID (0x0482), upon their request.
adb: Add five second timeout for USB writes on Linux host.
Add missing newlines to adb usage message
adb: do not mix printf() with write() when writing to stdout.
Added ZTE's USB Vendor ID (0x19D2) upon ZTE's request.
Added USB vendor id of Sharp, based on Sharp's request.
This is the first CL of a somewhat larger effort which, among other things,
will involve changing the emulator and ddms to talk to adb running on a
configurable port.
The port can be configured using environment variable ANDROID_ADB_SERVER_PORT.
Further CLs will also address the set of ports used for the local transport.

This was used for adb networking, which no longer exists.
This code also failed when adb was not running as root.

libacc was allocating memory using malloc for executable pages.
When running on a system where the stack and heap are not
executable, using malloc for executable pages will result in
a segfault.
This change modifies libacc to allow the code to run, even
if the system is running with executable stack and heap disabled.

make doesn't seem to handle the absolute symlink from
$OUT/root/sbin/ueventd to /init well - it follows the link during
dependency resolution, decides $OUT/root/sbin/ueventd doesn't exist
because /init doesn't exist, and relinks it every time.

When the init process ran out of actions to execute, cur_action was
NULL and action_queue_empty() was true, but cur_command was still
set. This patch clears cur_command when a new action is retreived,
and only depends on cur_action and action_queue_empty() to determine
the poll timeout.
