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
behavior.

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.

The name "client" is somewhat misleading as it also contains the host
side adb server, but it's a part of the client binary.
