Previously we've set these from /system/etc/mkshrc, which caused a behavioral
difference between interactive and non-interactive shells.

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

When the client exits (e.g. with Ctrl+C) the subprocess should be
notified as well so it can cleanup if needed.

Adds functionality for handling stdin/stdout/stderr streams and exit
codes using the shell protocol.
This CL just contains implementation for adbd which will not yet be
enabled. Once we have the ability to query transport features from the
adb client, another CL will add the implementation for the client side
and update the feature list to turn this on.
Note: this CL must be submitted together with a minadbd CL to update
the service_to_fd() function signature.

Refactor shell_service.cpp to remove dependencies on service.cpp and
combine some common logic between PTY and raw subprocesses.
This will make it easier to add additional common code paths for
the upcoming shell protocol.

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
the shell service. Everything else has been copied exactly as-is in
order to make it easier to determine what's changing in upcoming CLs.
