The adb gadget driver used to reset the USB bus when the adbd daemon exited,
and the host side adb relied on this behavior to force it to reconnect
with the new adbd instance after init relaunches it. The new gadget
drivers no longer automatically reset the USB bus when adbd is restarted
which caused adb to hang since it was no longer forced to reconnect with the
device. We attempted to work around this on the host side adb, but that
work around has not been reliable.
This change adds a property trigger on the service.adb.root system property
which will reset the USB bus and restart the adbd daemon when adbd sets
the property to 1. This should be much closer to the previous behavior
and will hopefully fix some problems with automated testing.

It won't actually do anything until the 'bu' tool and framework are
updated to respond properly, but this is the adb side of the
necessary infrastructure: we copy the tarfile into the socket pointed
at the device, using the existing mechanisms.

* Add support for correctly handling subprocess termination in shell service (b/3400254 b/3482112 b/2249397)
- have a waitpid() track the subprocess, then notify the fdevent via a socket
- force an eof on the pty master in fdevent's new subproc handler.
- modify fdevent to force-read the pty after an exit.
* Migrate the "shell:blabla" handling to "#if !ADB_HOST" sections, where it
belongs.
* Fix the race around OOM adjusting.
- Do it in the child before exec() instead of the in the parent as the
child could already have started or not (no /proc/pid/... yet).
* Allow for multi-threaded D() invocations to not clobber each other.
- Allow locks across object files.
- Add lock within D()
- Make sure sysdesp init (mutex init also) is called early.
* Add some missing close(fd) calls
- Match similar existing practices near dup2()
* Add extra D() invocations related to FD handling.
* Warn about using debugging as stderr/stdout is used for protocol.
* Fix some errno handling and make D() correctly handle it.
* Add new adb trace_mask: services.
* Make fdevent_loop's handle BADFDs more gracefully (could occur some subproc closed its pts explicitely).
* Remove obsolete commandline args reported in help. (b/3509092)

Ext4 filesystems like to be unmounted before rebooting. The Android system
doesn't have a traditional Linux init setup, and shutting down the system
was not much more than calling sync(2) and reboot(2). This adds a new
function to libcutils called android_reboot(). By default, it calls sync()
and then remounts all writable filesystems as read-only and marks them clean.
There is a flag parameter in which the caller can ask for sync() not to be
called, or to not remount the filesystems as read-only. Then it will call
reboot(2) as directed by the other parameters. This change also updates
adb, init and toolbox to call the new android_reboot() function.
Fixes bugs 3350709 and 3495575.

* Handling of the subprocess and its FD.
This fixes http://b/3400254 "Many bugreports getting hung at the end in monkey"
- Start up a service thread that waits on the subprocess to terminate,
then closes the FD associated with it.
- Have the event handler select() with a timeout so that it can
detect the closed FD. Select() with no timeout does not return when an FD is closed.
- Have the event handler force a read on the closed FD to trigger the close sequence.
- Migrate the "shell:blabla" handling to "#if !ADB_HOST" sections.
* Fix the race around OOM adjusting.
- Do it in the child before exec() instead of the in the parent as the
child could already have started or not (no /proc/pid/... yet).

accept() creates a new file descriptor that should be closed on exec so
that forked processes don't keep a fd opened on the socket.
This also fixes b/3297070 where adb hangs after running adb on the
target.

This reverts commit be0045aafd.
This change broke compatibility with previous versions of adbd, so I will be implementing this
by modifying the bugreport command on the device instead.
This allows dumpstate to run as root even if adbd is not.

Added new commands:
adb connect <host>:<port> (to connect to a device via TCP/IP)
adb tcpip <port> (to restart adbd on the device to listen on TCP/IP)
adb usb (to restart adbd on the device to listen USB)

This will allow rebooting the device via adb on any build, including user builds.
An optional argument can be provided
(for example, "adb reboot bootloader" or adb reboot recovery")

For adb shell commands (as well as shell based commands like logcat and bugreport) we now
batch USB writes into 4K chunks instead of sending small packets of data as they come in.
A timeout prevents us from blocking for more than 100ms when our 4K buffer is partially full.

For non-interactive adb shell commands, batch USB writes into 4K chunks
instead of sending small packets of data as they come in.
Add a timeout so we do not block for more than 200ms when our 4K buffer is partially full.
