Currently adb only realizes a TCP transport has gone away when it tries
to send a packet, which caused problems in particular for `adb reboot`
since no packets are sent, leading to the client hanging until Ctrl+C.
This CL turns on TCP keepalive packets to send 1 packet every second,
allowing up to 10 failures before disconnecting. Using built-in TCP
functionality turns out to be much cleaner in this case than trying to
implement our own keepalive packets at the application layer, and
should be more lightweight since it's all done in the TCP stack.

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.

(cherry picked from commit b5fea14e13)
This CL moves the network address parsing function from adb to libbase
so that it can be used by fastboot as well as adb.
libbase seemed like the right choice because:
1. It already has some parsing functions (parseint)
2. The net address parsing function uses the libbase string
functions so we have a libbase dependency anyway.
The parsing function has been modified slightly to make the canonical
address optional, and debug logging on success has been removed.
For adb the only functional difference is that parsing a network
address will no longer print the result to the debug log, which seemed
unnecessary.

Without -s argument, adb wait-for-device will make a call to
acquire_one_transport() with sinfo->serial.c_str() == "".
Waiting for acquire_one_transport() to be reworked to use std::string
rather than const char * for serial, work around this by passing NULL
when sinfo->serial is not initialized in host_service_to_socket().

The current implementation of the host commands "adb wait-for-*" allows
to specify only the transport layer (local, usb or any).
This patch allows the specification of the expected device state
(bootloader, recovery, device or sideload), this is usefull for
scripting purposes.
Use case:
$ adb reboot sideload-auto-reboot
$ adb wait-for-usb-sideload && adb sideload package.zip

Unfortunately, this isn't backwards-compatible with the current shell
protocol because we made unknown shell: arguments errors. We could try
to commit the change to make them just warnings first, but how would
we know when everyone was running adbd with that change? Bumping the
protocol version doesn't help because that only affects the code running
on the host. And although we could add another feature to the reported
features, since shell_v2 is still in development, that doesn't seem
worthwhile.

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.

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.

Upcoming changes to the shell will require significant additions to
the subprocess code, and it will be cleaner if it's in a separate file.
The only functional change here is a new debug tag specifically for

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).

First, HOST is always 0 in adbd, which matches ADB_HOST=0.
Second, HOST is always 1 when adb_main is called, which matches ADB_HOST=1.
For adb client that doesn't call adb_main, it never touches local_init(),
init_transport_registration() and fdevent_loop(). So the changes in adb.cpp,
services.cpp and transport_local.cpp do nothing with it.
As a conclusion, I think we can remove HOST and use ADB_HOST instead.

Call getaddrinfo() for connecting to IPv6 destinations.
Winsock APIs do not set errno. WSAGetLastError() returns Winsock errors
that are more numerous than BSD sockets, so it really doesn't make sense
to map those to BSD socket errors. Plus, even if we did that, the
Windows C Runtime (that mingw binaries use) has a strerror() that does
not recognize BSD socket error codes.
The solution is to wrap the various libcutils socket_* APIs with
sysdeps.h network_* APIs. For POSIX, the network_* APIs just call
strerror(). For Windows, they call SystemErrorCodeToString() (adapted
from Chromium).
Also in this change:
- Various other code was modified to return errors in a std::string*
argument, to be able to surface the error string to the end-user.
- Improved error checking and use of D() to log Winsock errors for
improved debuggability.
- For sysdeps_win32.cpp, added unique_fh class that works like
std::unique_ptr, for calling _fh_close().
- Fix win32 adb_socketpair() setting of errno in error case.
- Improve _socket_set_errno() D() logging to reduce confusion. Map
a few extra error codes.
- Move adb_shutdown() lower in sysdeps_win32.cpp so it can call
_socket_set_errno().
- Move network_connect() from adb_utils.cpp to sysdeps.h.
- Merge socket_loopback_server() and socket_inaddr_any_server() into
_network_server() since most of the code was identical.

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
specific error code.

Document the differences between adb_*() and unix_*() in the function
prototypes in sysdeps.h. See the file for the details (CR/LF

Fix adb_read(), adb_write(), and adb_close() calls that should really be
unix_read(), unix_write(), and unix_close(). Note that this should have
no impact on unix because on unix, unix_read/unix_write/unix_close are

Currently it requires manual key press to enter the sideload mode. This
CL adds 'adb reboot sideload' to reboot the device into sideload mode
directly with text display on. With 'adb reboot sideload-auto-reboot',
it will reboot after the sideload regardless of the installation result,
unless interrupted by user.
Since it needs to write to /cache/recovery/command file, 'adb root' is
required before calling 'adb reboot sideload' and the one with
'-auto-reboot'.
Also it requires the matching CL in bootable/recovery.

well just do this now.
usb_linux_client.c is going to stay as C because GCC isn't smart
enough to deal with the designated initializers it uses (though for
some reason it is in C mode).
The Darwin files are staying as C because I don't have a way to test

The Windows files are staying as C because while I can actually build
for them, it's slow and painful.
