Previously, we were returning the result of SendOkay/SendFail in a few
places after handling a host request, which is incorrect for two
reasons. First, the return type of SendOkay/SendFail is bool, and
handle_host_request was expected to return 0 on success. Second, we
don't care if the SendOkay fails; if we got to that point, we're done
with the request, regardless of whether we succeeded to report our
result. The result of this was a spurious failure result reported after
the initial result, which was ignored by the adb client.

This CL builds the former `libadbd` as a shared library, and moves
`adbd` to using shared libraries.
We can't switch `libadbd` from static to shared library directly, due to
the circular dependency between `libadbd` and `adbd`. In particular,
daemon_service_to_fd() can't be compiled into `libadbd`, as it needs to
be overridden by recovery/minadbd.
This CL creates a static library `libadbd_core` as the common base,
which contains everything from the former `libadbd`. Both of the two
shared library targets `libadbd` and `libadbd_services` depend on
`libadbd_core`.
The `adbd` on device (under both of normal boot and recovery) now
depends on `libadbd.so` and `libadbd_services.so`. recovery/minadbd will
depend on `libadbd.so` and `libminadbd_services.so` in future (after
fully converting recovery to Soong).

Previously, when a TCP connection was disconnected from adbd, we were
registering it with ReconnectHandler, which led to the transport
sticking around after the socket was closed. Due to the naming of
TCP transports in adbd (host-<fd number>), this results in incoming
connections being immediately closed if their file descriptor number
ends up being the same as a TCP transport that had previously
disconnected.

commandline.cpp includes commandline.h which defines
StandardStreamsCallbackInterface which calls fwrite(). In the
compilation unit for commandline.cpp, fwrite is getting remapped to
adb_fwrite (good), but the compilation unit for bugreport.cpp includes
sysdeps.h pretty late, which prevents fwrite from getting remapped to
adb_fwrite.
Apparently when linking, the version of StandardStreamsCallbackInterface
that gets used is the one from bugreport.cpp's compilation unit, which
doesn't call adb_fwrite().
And it's necessary to call adb_fwrite() to get Unicode console output on
Windows.
The fix is to #include "sysdeps.h" earlier in bugreport.cpp. I searched
the other object files for other unremapped calls to printf/fwrite/etc.
and didn't find any.

adbd has been built as a static executable since the same binary was
copied to the recovery partition where shared library is not supported.
However, since we now support shared library in the recovery partition,
adbd is built as a dynamic executable.
In addition, the dependency from adbd to libdebuggerd_handler is removed
as debuggerd is handled by the dynamic linker.
A few more modules in /system/core are marked as recovery_available:
true as they are transitive dependencies of the dynamic linker.

An IOVector is a collection of immutable reference counted blocks which
can have its head detached at an arbitrary index. This is extremely
useful for implementing packet-framed protocols like adb on top of a
stream protocol like TCP: a stream reader can read blocks, append them
to the end of the IOVector, and then pull packets off of the front.
This also lends itself naturally towards scatter/gather I/O, which will
enable us to read data from disk and send it across the wire with a
theoretical minimum number of copies in USB, and one extra copy over
TCP.
Since this is basically a generalization of std::deque<Range>, delete
Range and replace its uses with IOVector.

io_submit sleeps waiting for the gadget
to be enabled. Currently if that sleep
is interrupted it will shut down adb,
causing it to have to start back up again.
Rather than return EINTR if interrupted,
io_submit actually completes and the EINTR
is found later when looking through events.
Since an io that is interrupted will be
small anyway, add a loop to retry small ios.
Also upgrade aio logs in accordance with
their importance.

The tags property is (and has always been) unused by Soong. The property has
been defined as a list of strings, and the `androidmk` converted any
LOCAL_MODULE_TAGS entries over to it, but we've never done anything with it.
In preparation for removing the definition from Soong, I'm removing it from all
Android.bp files in the tree.
Since this has never done anything, this is a no-op, but if you really did want
the Android.mk behavior, the proper way to define a module to be installed in
userdebug / eng builds is to use PRODUCT_PACKAGES_DEBUG or PRODUCT_PACKAGES_ENG
in the appropriate product makefile.

Test: remove `tags` from Soong, see errors go away.
Add two states: connecting and authorizing, to disambiguate the offline
and unauthorized states, respectively.
Previously, devices would transition as follows:
offline -> unauthorized -> offline -> online
offline -> unauthorized (when actually unauthorized)
With this patch:
connecting -> authorizing -> online
connecting -> authorizing -> unauthorized (when actually unauthorized)
This allows test automation and the like to distinguish between offline
devices, unauthorized devices, and working devices without having to
do retry loops with arbitrary sleeps on their end.

This change is in preparation to allow the TCP-based transports to be
able to reconnect. This is needed because multiple threads can access
the Connection object. It used to be safe to do because one instance of
atransport would have the same Connection instance throughout its
lifetime, but now it is possible to replace the Connection instance,
which could cause threads that were attempting to Write to an
atransport* to use-after-free the Connection instance.

This change adds a callback that is invoked exactly once, either when
the connection is fully established (i.e. CNXN packets have been sent
and received) or the atransport object is deleted before that (because
the connection failed).
This helps in distinguishing between successful and failing connections
for TCP. Especially when there is some kind of port
forwarding/multiplexing in between (like an SSH tunnel or SSLH proxy).

Profiling of adb_benchmark revealed that something like half of the CPU
time was being spent in malloc and free, which was odd because the
benchmark repeatedly mallocs and frees allocations of the same size. It
turns out that our default configuration of jemalloc will purge after
every free. Configure jemalloc to not do this, for gains of over 100%
on adb_benchmark, and up to 25% (on walleye USB3) in real-life.

On platforms that implement sockets via underlying sockets (e.g. Wine),
a socket can appear to be full, and then become available for writes
again without read being called on the other end. Add a sleep after
each write to give the underlying implementation time to flush.

but at least in the case of Wine, that doesn't seem to be the case.

Previously, processes started via `adb shell` have an oom_score_adj of
-1000, making them invisible to the oom killer. This makes running a
process that consumes all memory (e.g. by leaking in a loop) lead to

heuristics in the kernel) being oom killed before getting to it.

If we get a ton of fdevent_run_on_main_thread calls while running one
of the handlers, the socket might become full, which will result in a
deadlock in fdevent_run_on_main_thread when a write to the fd blocks
with the mutex taken. Resolve this by making the fd nonblocking, which
is safe because we always write after appending to the list, and read
before emptying the list, which guarantees that if the byte we write is
consumed, the std::function we appended will be run.
