Add reconnect command for debugging. `reconnect` kicks a transport
from the host side, `reconnect device` kicks a transport from
the device side. They can be used to produce transport errors.

Currently targeting a device by serial requires matching the serial
number exactly. This CL relaxes the matching rules for local transports
to ignore protocol prefixes and make the port optional:
[tcp:|udp:]<hostname>[:port]
The purpose of this is to allow a user to set ANDROID_SERIAL to
something like "tcp:100.100.100.100" and have it work for both fastboot
and adb (assuming the device comes up at 100.100.100.100 in both
modes).
This CL also adds some unit tests for the modified functions to make
sure they work as expected.

Windows restricts the return value of threads to 32-bits, even on 64-bit
platforms. Since we don't actually return meaningful values from thread,
resolve this inconsistency with POSIX by making adb's thread abstraction
only take void functions.

The current permission messages can be confusing for users who don't
know about udev and USB access permissions. This CL adds some checks to
try to identify common udev problems, and adds a link to online
documentation.
Example messages:
1) adb server is in plugdev group but access is still denied:
$ adb devices
List of devices attached
082f59270073e1e3 no permissions (verify udev rules); see [developer.android.com/tools/device.html]
2) plugdev group exists but adb server is not in it:
$ adb shell
error: USB permission failure: udev requires plugdev group membership.
See [developer.android.com/tools/device.html] for more information.
3) plugdev group does not exist:
$ adb shell
error: USB permission failure.

still be using them, potentially causing a crash, and definitely

I've been using these changes to compile with Visual Studio.
- GetFileBasename(): __FILE__ uses \ with Visual Studio.
- adb_trace.cpp: Apparently VS needs an ampersand before the function name.
- "expr1 ? : expr2" is a GCC extension.
- <algorithm> contains std::min().
- seekdir can't always be #define'd because some headers have members
named seekdir.
- adb_utils.cpp: Not really a compiler issue, just a random fix:
0x7F/DEL is not printable.

use the cmd command. Additionally, the APK will be streamed directly to
package installer instead of creating a temporary file.

ddmlib does not use the ADB client, but instead connects directly to
the adb server. This breaks some of the assumptions I previously made
when enabling the shell protocol.
To fix this, the adb server now defaults to no protocol for the
standalone command, and the shell protocol must be explicitly requested
by the client. For example:
shell:echo foo -- no shell protocol
shell,v2:echo foo -- shell protocol
As long as I was touching the shell service arguments I also changed
them to no longer duplicate the command-line arguments. This allows
more flexibility to change the adb client CLI if necessary and makes
the code more readable.

Previously the transport features list was only overwritten if a
new feature list was found. However, adbd can reuse the same atransport
object even if the adb server is killed and restarted, so the feature
list was not cleared properly if the newly started adb server didn't
provide one.
This CL fixes the bug by clearing the transport features list whenever
a connection banner is parsed.

Devices get a list of supported features from the adb server, not the
client, so a mismatch between client and server features can cause the
device to use an incorrect feature set.
Bumping the server version is the easiest way to make sure the client
and server features match and seems like the best solution at the
moment.
A more automated fix could be to compare client/server features on each
connection and restart if they don't match. This requires an extra
client <-> server round-trip per command, but removes the need to
manually bump the server version number on feature change. Unless the
feature set changes often it didn't seem worth the extra overhead.

Adds -T (no PTY) and -t (force PTY) options to `adb shell` to mimic
ssh options. Small cleanup to send an entire FeatureSet to the adb
client at once to avoid multiple round-trips when querying multiple
features.
Known issue: humans using `adb shell -T` to start a non-PTY interactive
session may experience problems since neither side will have PTY
features like echoing or newline translation. This is probably OK for
now as the -Tt options are primarily useful for scripting.

The old names seems confusing. output_thread was reading remote data and writing to
local sockets. input_thread was reading local sockets data and writing to remote.
This change tries to make it clear by renaming output_thread to read_transport thread,
and renaming input_thread to write_transport thread.

Currently run_transport_disconnects() are called twice. One is in
handle_offline(), another is before destroying transport.
The users of disconnect callback are listener, adb_auth_client, and
remote_sockets. All of them need only to be called once. And after
handle_offline, no new listeners, adb_auth_client, or remote_sockets
can be connected to the offlined transport. So I think we can remove
the second call to run_transport_disconnects().
Change-Id: I1ef8b6b7b5ab7ae1bad109be107c85973d65a2e3
Transport atransport objects are semi-reference counted: the input and
output threads each hold a reference. The adb disconnect command was
calling transport_unref to release a reference that it never had in the
first place. This meant that the refcount dropped to zero and the object
was deleted before either the input or output thread released its
reference. When that last thread released its reference, it wrote to
freed memory and also sometimes crashed.
This fix is to not release any unheld reference, instead it just kicks
the transport to break remote_read in output_thread. So all transport
close flow goes the following way:
output_thread (exit) -> main thread (offline the transport) ->
input thread (exit) -> main thread (destroy the transport)

It is reported by tsan as a double checked locking. But I think
it is not a real data race. Because I think the old code is able
to make sure t->kick() is only called once, and the caller of
kick_transport is not relying on the side-effect of calling
t->kick().
But as it is not perf critical, I don't mind breaking the double
checked locking pattern.

As far as I can see, all asockets operations happen in fdevent_loop()
in the main thread, excepting close_all_sockets(). Instead of adding
lock and ref_count for each asocket, a simpler way would be moving
close_all_sockets() from input_thread to the main thread.
In input_thread(), there are two path to break the loop and call
close_all_sockets(). One path is when receiving offline A_SYNC, which
is sent by the main thread. The other path is when read_packet
fails, which I believe is almost not possible and doesn't matter
(Because t->fd is closed just before t is freed.). So I move
close_all_sockets() to handle_offline() in the main thread.
the socket_list_lock in sockets.cpp could be removed. But I prefer
to leave it for the following changes.

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).

This allows us to test for features explicitly rather than relying on
the protocol version number, allowing us to fall back gracefully if a
feature is not supported.

The reason behing this change is to increase the adb push/pull speed
with reduceing the number of packets sent between the host and the
device because the communication is heavily bound by packet latency.
The change maintains two way compatibility in the communication
protocol with negotiating a packet size between the target and the
host with the CONNECT packets.
After this change the push/pull speeds improved significantly
(measured from Linux-x86_64 with 100MB of data):

Add missing \n to uses of legacy D() macro. This should make the legacy
logging easier to read (and harder to miss important stuff).
On POSIX, use gettid() from libcutils instead of pthread_self() so that
the output shows a more reasonable number instead of a pointer value.
This should be ok since libbase's logging already uses gettid().
Win32:
Don't let the Win32 last error get overwritten by API calls after the
original error'ing API. When encountering an unknown error, log the
