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.

This is another step towards being able to swap toolbox ps out for
a more complete ps. This should also let us fix dumpstate to not
need a separate "ps -Z" run --- we can just add -Z to the previous
run of ps instead.

Regular ps doesn't have this, and at least in our tree everyone
seems to actually pipe to grep instead of using this anyway. But
since the switch to a more full-featured ps is going to be a nightmare
anyway, let's dip a toe in the water by removing something we don't plan
on supporting.

NB: monotonic is a best estimate and may be out by a few ms

So that this daemon doesn't change on every build, use the system build
date from libchrome (which reads ro.build.date). That way we don't have
to update this daemon for every OTA.

ssh has slightly more sophisticated -Tt options that we want to match.
This CL changes -Tt behavior to match ssh so that we allocate a remote
PTY in these cases:
-T: never.
: if stdin is a terminal and user wants an interactive shell.
-t: if stdin is a terminal (otherwise print a warning message).
-t -t: always.
Now this will work as expected:
$ adb shell < my_script.sh
Also corrects a small unrelated bug with escape sequences so that only
a single tilde is accepted for the disconnect sequence.

I fixed the server side to send detailed error reports, but the client-side
code for pull was broken because it had already read the "FAIL" header before
calling the general error reporting code that expects to be able to read
the header. This meant we'd always report that we failed to read the failure
message.
Also add a couple of missing "\n"s, make sure every error message is prefixed
by "adb: ", and remove a useless path length check that would silently ignore
over-long paths rather than relying on SendRequest to detect and report the
problem.
