bugreport() will be soon refactored to track progress, which will
require more comprehensive unit tests.
As such, it's better to move it to its own files, which in turn also
requires moving send_shell_command() and usage() to commandline.h.

This CL adds support to forward or reverse TCP port 0 to allow the
system to automatically select an open port. The resolved port number
will be printed to stdout:
$ adb forward tcp:0 tcp:8000
12345
$ adb reverse tcp:0 tcp:9000
23456
This allows testing to be more robust by not hardcoding TCP ports which
may already be in use.
Forwarding port 0 is a host-only change and will work with any device,
but reversing port 0 requires the device to be updated with a new adbd
binary.
This CL also does a little bit of cleanup such as moving the alistener
class out of adb.h, and adds some error checking and additional tests.

Shell scripts of the following form do not work properly with adb:
echo "foo\nbar\nbaz" | {
read FOO
while [ "$FOO" != "" ]; do
adb shell echo $FOO
read FOO
done
}
The first run of adb shell will consume all of the contents of stdin,
causing the loop to immediately end. ssh solves this by providing a -n
flag that causes it to not read from stdin. This commit adds the same.

We're now able to send packets faster than the device can handle them,
meaning that sometimes we're several packets through before the device
says "hey, wait, I can't write" and closes the connection. At best this
led to us reporting that we couldn't sync because "Connection reset";
at worst we'd get SIGPIPE because we were still streaming to a connection
that had already been closed.
This change renames adb_main adb_server_main, and moves the ignoring of
SIGPIPE into adb_commandline so it applies to both client and server (but
not adbd).
This change doesn't address the "wrong error message" part of the problem,
but at least it means you'll get *an* error message.

adb_getenv() should be case-insensitive just like the real getenv() on
Windows.
Added a unittest for adb_getenv(). In the process, made adb_test link
with -municode so that the environment block is Unicode.
Move wmain() from main.cpp to sysdeps_win32.cpp so that adb_test could
also use it.
Because wmain() moved, it wasn't as easy to do the runtime check to
verify that -municode was used, so do that check in _ensure_env_setup()
since adb_getenv() is called early in adb anyway.
Added a utility ToLower() which is good enough for env vars whose keys
are probably always ASCII to begin with.

When launching the adb server (typically from adb start-server),
redirect stdout/stderr to anonymous pipes which are read by threads in
the parent process, to make error diagnosis easier.
If there is an error during adb start-server, the output looks like:
> adb start-server
* daemon not running. starting it now on port 5037 *
error: could not blah # from server process
could not read ok from ADB Server # from launch_server
* failed to start daemon * # from adb_connect
error: cannot connect to daemon # from adb_commandline
Fix handle-leaks in launch_server by using new unique_handle class
that is based on std::unique_ptr.
In the server, close stdin and redirect to adb.log *before* sending the
ACK, so that any errors are reported early instead of after the ACK.

even though everything is working ok.
- adb_connect()
- If we can't parse the version string, explain this in error output
and don't goto error which would try to close an fd we already closed.
- If host:kill doesn't work, output error info. Don't try to close
already closed fd.
- adb_main()

this will ever get hit).

- handle_forward_request
- Because we have detailed info about which syscall failed (at least
on Win32), use a more generic prefix of "cannot bind listener" followed
by the detailed info.
- install_listener
- Return string errors for a few errors even though I don't think any
callers actually output the string for those errors.
- Remove the printf since the callers print the message themselves.
- adb_main
- LOG(FATAL) calls abort() which on Windows calls the Windows Error
Reporting service which pops up a dialog asking if you want a
crashdump to be uploaded to Microsoft. So really, abort() is
designed for app bugs. Windows isn't the only one doing this, Chromium
also makes LOG(FATAL) crashdump-ready. Since an error here is not
necessarily an app-bug, use a 'normal' error output API like fatal()
which prints an error and just uses exit().
- sysdeps_win32.cpp
- When Winsock APIs fail, make the string clarify which API failed.
Use terse unix-style descriptions (like what you'd get from
cp/mv/dd/etc.).
- Don't trace WSAEWOULDBLOCK from recv() which is a normal occurrence.
- Add a comment about WSAEWOULDBLOCK => EAGAIN.

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.

The win32 version of 9f2d1a9cfc. The big
technique is to fit a Win32 HANDLE value in an int because it only uses
32-bits. This allows most of the other adb code to stay the same.

erroneously returning an error when --reply-fd was not used, which

When "adb start-server" is issued, and a server needs to be launched,
adb client forks itself and the child process runs the server routine.
Once the server initializes its various components, it sends an "OK\n"
back to the client via its stderror (or stdout on Windows).
This sequence breaks down if before sending the "OK\n", the server
happens to log something on its stderr. In order to avoid this, the
client now expects the ack to come on a different fd rather than one
of the standard streams.

Initial support for Unicode file/dir names. Unicode paths can be passed
on the command line, directory enumeration can enumerate Unicode paths,
Unicode paths are used for file access, and Unicode paths can be output
on the console correctly.
Also Unicode environment variable access.
Initial support for Unicode output from adb shell (which uses
adb_fwrite()). This is partial because the corner case of an
adb_fwrite() call with an incomplete UTF-8 multi-byte sequence does not
output correctly, but this should be uncommon, is better than what we
had before (*always* incorrect UTF-8 multi-byte sequences) and can be
fixed in the future.
Calls to Windows APIs with char strings were changed to pass wchar_t
strings to the FooW() variants.

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.

In the adb client, redirect stdin and stderr of the adb server to `nul',
so that when the adb server starts up, it avoids issues in the C Runtime
where it closes stderr, making it hard to properly reopen. There are
probably other ways to avoid this issue, but I think this is the
cleanest that will keep working over the years and will exercise the
most commonly used code-paths in the C Runtime.
Fix some adb_close() calls to be unix_close() (only really matters on
Windows).
Make stderr non-buffered on Windows, to match the (sensible) Linux

Any output from the LOG family will now go to stderr and logcat on the
device. stderr is usually redirected to a log file, but that is now
inhibited for adbd if being run from a tty (useful when debugging with
the serial console).
This also fixes sending logs to the file on device for the trace mask
of "all". The "all" tag was specifically handled to return early from
the function, preventing the file initialization from happening.

The daemon failed to startup because main.cpp was changed from calling
WriteFile() to android::base::WriteStringToFd(), the later which calls
write() in the C Runtime which by default has stdout in textmode which
does \n to \r\n translation.
The quick fix is to change stdout's mode from text to binary since right
after it is reopened to redirect to the daemon log file anyway.
