Add an implementation of std::make_unique for Windows, where we're
currently stuck with C++11, and switch some uses of new over to it.

ba4d9fd933 Set $HOSTNAME in adbd.
bash sets this itself, but mksh doesn't.

This also makes interactive and non-interactive adb shells more similar,
because when we set this in mkshrc that wouldn't affect non-interactive
shells. (I'm not sure whether this is an improvement or not.)

This is certainly _cheaper_ than doing this in mkshrc by calling out to
getprop though.

924d35a8d5 adb: extract the adb-specific unique_fd out into its own header.
Some POSIX-only files would like to use functions declared in
adb_utils.h without being forced to use the sysdeps stuff for open,
close, etc. Extract the adb-specific unique_fd into its own header so
those files can use adb_utils.h alongside the real unique_fd.

cd5d7376dc adb: don't dup local socket fd.
SIGHUP handling depends on the local socket fd being fully closed in
order to trigger an event on its counterpart. Release the local socket
fd inside of Subprocess when returning it to ensure this.

Functionally, a cherry-pick of internal commit 42afe20.

344778da41 adb: fix fd double close, Subprocess lifetime issue.
This commit fixes two somewhat related issues in shell_service.

  - The fd returned by StartSubprocess is owned by a unique_fd
    contained in the Subprocess object, but also gets closed by the
    caller. Resolve this by duping the returned file descriptor.

  - A Subprocess object can be destroyed immediately after its initial
    construction in StartSubprocess if we're sufficiently unlucky.
    Split up the fork/exec and "start management thread" steps, so that
    we can safely do everything we need to do on the Subprocess before
    handing it over to the thread that'll eventually destroy it.

f2aa186c7b adbd: properly close subprocess pipes on Ctrl+C.
When non-interactive sessions exit via Ctrl+C, adbd sends SIGHUP
to the child process to let it know to exit. However, adbd was not
closing the pipes to the child process, so if the subprocess ignored
SIGHUP and continued writing it could fill up the pipe and block
forever while adbd waits for it to exit.

This CL adds the necessary calls to close the subprocess pipe after
sending SIGHUP.

b5fea14e13 adb: make adb_thread_func_t return void, add adb_thread_exit.
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.

57dd5ae1e3 adb: fix subprocess termination for legacy shell.
http://r.android.com/166419 changed `adb shell` behavior to not
allocate a remote PTY for non-interactive commands, but adbd relied on
having a PTY to properly terminate the subprocess.

One impact of this is that when using older versions of adb or passing
the -x flag, `adb screenrecord` wasn't properly terminating and closing
out the video file.

This CL restores the old behavior for legacy shell connections: always
use a PTY, but put it in raw mode if the client is doing local PTY
input/output processing itself.

9b3fd67213 adb: don't use setenv after forking.
Previously, for `adb shell`, we were using setenv after forking to set
up the child's environment. This would occasionally deadlock in the
child, which would cause the main thread to deadlock waiting for the
child to complete. This patch constructs the environment before forking
and passes it to execle, eliminating the deadlock.

18ddf5c6a2 Pass $TERM to the device.
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.

1ed57f0dc3 adb: non-interactive shell stdin.
Non-interactive `adb shell` previously only read from the remote shell,
but we want it to write as well so interactive and non-interactive
shells can both send data. With this CL, we can now do:
  $ echo foo | adb shell cat
  foo

This is primarily usable with newer devices that support the shell_v2
features. Older devices will receive stdin but the shell will still
hang after all input has been sent, requiring user Ctrl+C. This seems
better than closing communication altogether which could potentially
miss an unpredictable amount of return data by closing too early.

Known issue: non-interactive stdin to a PTY shell isn't reliable.
However I don't think this is a common case as ssh doesn't seem to
handle it properly either. Examples:
  * echo 'echo foo' | adb shell
  * echo 'foo' | adb shell -t cat
