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.

For the purpose of on-boarding all the other tests,
skip test_reconnect for now.

Switch to the nonblocking FFS implementation that fixes several race
conditions on connect/disconnect.

Change-Id: I91fdb9b27152078cb38e610861a05f1fa95aa3a2
Detect kernels that don't support AIO on functionfs endpoints and fall
back to the old legacy implementation.

This is a useful helper for anyone that's using thread safety
annotations alongside std::condition_variable, extract it from adb and
move it to libbase.
