adb was already using ConsumePrefix, and now we have another would-be
user in cutils. (There appears to be one place in adb that should use
ConsumeSuffix, so I'm assuming we'll want that sooner or later.)
I've kept these inline because adb and google3's versions both were, and
I'm easily led.

A previous patch intended to make receiving multiple FUNCTIONFS_ENABLEs
non-fatal, but failed to do so because we would try to spawn another

We don't need the public key to be generated at ~/.android/adbkey.pub,
but it's still useful to be able to generate the public key for use with

Each operation we submit results in a contiguous allocation in the
kernel which can trigger OOM-killing. Tune the queue depths to reduce
the chances of this happening, with a minimal impact on performance.

unique_fd's implicit conversion to int has led to tons of problems (see
all of the overloads for close, fdopen, fdopendir, etc.). Add a switch
that can turn it off, and reduce the ridiculous amount of work to fix up
callers by introducing a borrowed_fd type that can be constructed from
either int or unique_fd.

unique_fd's implicit conversion to int allows the following code to
compile without error, leading to a double close:
std::function<void(unique_fd)> func = [](int x) { close(x); };
func(unique_fd(42));

This CL adds client support to recognize the rescue mode (which will be
served by recovery image). It also allows waiting for a device to enter
rescue mode. The support for the actual rescue commands will be added in
follow-up CLs.

It seems like we don't actually always get these events in order, so
demote them to a log and restart the connection instead of aborting.

Occasionally, after we open the functionfs endpoint and write our
descriptors to it, we end up in a state where we never receive any
events from ep0, presumably due to a race against some other part of
the system, since adding sleeps reduces the likelihood. Add an
(arbitrarily chosen) timeout for the initial FUNCTIONFS_BIND we read,
and retry on failure.

If we fail to submit writes for some reason (e.g. the USB cable was
unplugged), another thread that's waiting on the write mutex can enter
SubmitWrites and attempt to resubmit the writes that we already failed
to submit, leading to a failed assertion of !IoBlock::pending.
Increment writes_submitted_ before actually calling io_submit, so we
skip over these writes and fall through to exit.

When a function argument takes a std::string, it's inefficient to
pass std::string::c_str(), since that creates an additional copy.
So we change these calling sites.

Previously, we were initializing IoBlock::pending when submitting a read,
but leaving it uninitialized when doing a write, which would sometimes
result in an assertion firing when we received a previously allocated
block of memory that happened to have a nonzero value in pending.

When we introduced __adb_check_server_version() as a function
returning a 'bool', we missed missed converting once instance
of "return -1;" to "return false;". Thus, we're returning 'true'
in this case as our non-zero value gets implicitly converted to
'true'.
We fix this case as well with this CL.
