As there is no security guarantee when the device is unlocked,
allowing adb root gives us more rooms to debug a USER build images.
Also, this makes it possible to run VTS on a USER build GSI, with
setting ro.debuggable=1 and unlocking the device.
This basically re-lands a reverted change:
https://android-review.googlesource.com/c/platform/system/core/+/437815
Which isn't needed after we moved /sbin/adbd to /system/bin/adbd in
USERDEBUG GSI. But it's still needed for USER build GSI.

Test: unlock a USER build device, check 'adb root' can work

If a device is unplugged, a BIND will happen without an ENABLE until the
device is plugged in, which would previously result in adbd crashing
every 5 seconds due to an attempt to join a thread that hadn't been
started.

Our servers can comfortably run more than 16 emulators, and this is
much easier than messing with hypervisors or docker port allocation.
Assumes you know how to avoid clashes with Google Wear's default port.
Test: manual - still registers emulators.

1. Don't clear O_CLOEXEC on an fd we're duping to stdin/out/err: dup2
does that for us if oldfd != newfd, and we know the fd can't be
stdin/out/err.
2. Use unique_fd.
3. Remove gotos by breaking the remount logic into its own function.

Replace direct logic in support for 'adb remount' with an exec out to
/system/bin/remount to do the heavy lifting. Remount success and
failure strings are reported by the adb remount service in response
to the various reported errors, freeing up the remount command itself
from the legacy of script expectations.

Reduce the operation sizes to sizes that are small enough that the
kernel will run the OOM killer to try to make them succeed. Compensate
for the smaller operation sizes by increasing the queue depth.

The kernel does a kmalloc of the write size for each write during
io_submit, which can lead to failure if the kernel's heap is fragmented
such that it can't allocate a contiguous 1MB chunk. Partition writes
into 16 page chunks which are much more likely to succeed.

Previously, there was a race where if adb root took longer than 3
seconds to take effect, we'd return early and allow subsequent commands
to be targeted at the still-not-dead transport, and spuriously fail.

Prerequisite for making `adb root` wait for the device that it told to
restart to disappear: the client needs to know which transport to wait
on.

It's error-prone to manually writing code of the following form:
if (foo.starts_with("some_prefix:")) {
foo.remove_prefix(strlen("some_prefix:"));
}
Add a helper to do that for us.

This is corresponding to exec: command of adb and allows for simplifed calls
to binder without shell protocol.
