27241a7a96 Revert "Revert "Add a way to turn off unique_fd's operator int.""
The original commit broke aosp-master-with-phones, because of
vendor libraries the depended on the int versions of libbase functions.

This patch reverts the revert, and also adds ABI-compatibility shims for
the replaced functions.

This reverts commit 2c58e1924a.

93d63c010a Add a way to turn off unique_fd's operator int.
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.

640407d632 Adding Android Binder Bridge (abb) utility launched from adbd.
Once launched, abb will listen for incoming Binder cli requests.
Executing in-process provides 6x latency improvement (125ms vs 25ms on
PixelXL) for commands like 'package path'

Intended usage by Android Studio for fast deployment and patching of APKs.

351ecd15b2 adb: fix adb client running out of sockets on Windows
Background
==========

On Windows, if you run "adb shell exit" in a loop in two windows,
eventually the adb client will be unable to connect to the adb server. I
think connect() is returning WSAEADDRINUSE: "Only one usage of each
socket address (protocol/network address/port) is normally permitted.
(10048)". The Windows System Event Log may also show Event 4227, Tcpip.
Netstat output is filled with:

  # for the adb server
  TCP    127.0.0.1:5037         127.0.0.1:65523        TIME_WAIT
  # for the adb client
  TCP    127.0.0.1:65523        127.0.0.1:5037         TIME_WAIT

The error probably means that the client is running out of free
address:port pairs.

The first netstat line is unavoidable, but the second line exists
because the adb client is not waiting for orderly/graceful shutdown of
the socket, and that is apparently required on Windows to get rid of the
second line. For more info, see
https://github.com/CompareAndSwap/SocketCloseTest .

This is exacerbated by the fact that "adb shell exit" makes 4 socket
connections to the adb server: 1) host:version, 2) host:features, 3)
host:version (again), 4) shell:exit. Also exacerbating is the fact that
the adb protocol is length-prefixed so the client typically does not
have to 'read() until zero' which effectively waits for orderly/graceful
shutdown.

The Fix
=======

Introduce a function, ReadOrderlyShutdown(), that should be called in
the adb client to wait for the server to close its socket, before
closing the client socket.

I reviewed all code where the adb client makes a connection to the adb
server and added ReadOrderlyShutdown() when it made sense. I wasn't able
to add it to the following:

* interactive_shell: this doesn't matter because this is interactive and
  thus can't be run fast enough to use up ports.
* adb sideload: I couldn't get enough test coverage and I don't think
  this is being called frequently enough to be a problem.
* send_shell_command, backup, adb_connect_command, adb shell, adb
  exec-out, install_multiple_app, adb_send_emulator_command: These
  already wait for server socket shutdown since they already call
  recv() until zero.
* restore, adb exec-in: protocol design can't have the server close
  first.
* adb start-server: no fd is actually returned
* create_local_service_socket, local_connect_arbitrary_ports,
  connect_device: probably called rarely enough not to be a problem.

Also in this change
===================

* Clarify comments in when adb_shutdown() is called before exit().
* add some missing adb_close() in adb sideload.
* Fixup error handling and comments in adb_send_emulator_command().
* Make SyncConnection::SendQuit return a success boolean.
* Add unittest for adb emu kill command. This gets code coverage over
  this very careful piece of code.

aa24549190 adb sync cleanup.
We can double the speed of "adb sync" (on N9) if we increase SYNC_DATA_MAX
from 64KiB to 256KiB. This change doesn't do that, because I still haven't
managed to plumb through the information about whether we're a new adb/adbd
to file_sync_client.cpp and file_sync_service.cpp. But this is already a big
change with a lot of cleanup, so let's do the cleanup and worry about the
intended change another day...

This change does improve performance somewhat by halving the number of
lstat(2) calls made on the client side, and ensuring that most packets are
sent with a single write. This has the pleasing result of making the null
sync on an AOSP N9 go from just over 300ms to around 100ms, which means it
now seems instantaneous (https://en.wikipedia.org/wiki/Mental_chronometry).

286bb6ddbd Revert "Turn on -Wformat-nonliteral."
One of my build aliases doesn't play nice with USE_MINGW=1, so my build lied to me. Will revert until I fix it up.

This reverts commit 459df8f3a1.

459df8f3a1 Turn on -Wformat-nonliteral.
Apparently there are two classes of this warning in clang.
-Wformat-security is only emitted for cases of
`func(nonliteral_fmt_string)` (no args), and -Wformat-nonliteral is
emitted for cases *with* arguments. For whatever reason, the latter
isn't included in -Wextra and must be manually enabled.

To make this more easily portable to Windows, move the existing
gnu_printf/__printf__ decision into base/macros.h as ATTRIBUTE_FORMAT.

e67f1f87d9 More adb buffer fixes.
This patch factors out a lot of the basic protocol code: sending OKAY,
sending FAIL, and sending a length-prefixed string.

ADB_TRACE has been non-optional for a long time, so let's just remove
the #ifs.

Also actually build the device tracker test tool (and remove its duplicate).

cc731cc767 Test readx/writex (now renamed).
Renamed readx/writex to ReadFdExactly/WriteFdExactly respectively.
These read/write a full fixed-size buffer. If the whole buffer cannot
be read/written, these functions return an error.

Rename write_string to WriteStringFully.

Move the TEMP_FAILURE_RETRY definition in sysdeps.h out of the
!Windows section. It seems Windows won't actually interrupt a call,
but it's easier to just define it than to #ifdef each call.
