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.

During early boot, we may be mounting and unmounting /data.
Having the home directory for adb shell commands, such as
"adb shell logcat", on the /data directory prevents unmounting.
This reverts commit 173eb396c7.

We had mostly-working hacks before, but it's time to just modify LinePrinter
to suit our needs. If we tell LinePrinter what kind of output we're giving
it, it can manage things automatically.
This fixes the minor bug where we'd sometimes have a blank line after an
error message.

Make the home directory for adb shell be /data/local/tmp and
automatically change into that directory.

Also, inline the bulk_read and bulk_write functions which were only
being used by one other function.

The current permission messages can be confusing for users who don't
know about udev and USB access permissions. This CL adds some checks to
try to identify common udev problems, and adds a link to online
documentation.
Example messages:
1) adb server is in plugdev group but access is still denied:
$ adb devices
List of devices attached
082f59270073e1e3 no permissions (verify udev rules); see [developer.android.com/tools/device.html]
2) plugdev group exists but adb server is not in it:
$ adb shell
error: USB permission failure: udev requires plugdev group membership.
See [developer.android.com/tools/device.html] for more information.
3) plugdev group does not exist:
$ adb shell
error: USB permission failure.
See [developer.android.com/tools/device.html] for more information.

If we stat a file and get a size of 0, and then successfully read bytes
from that file, we would previously divide by zero when calculating the
percentage completion of the file. This case happens either when we're
racing against something else writing to the file, or when we're pulling
magical files such as the ones in /dev/cpuctl/ that lie about their
size.

The previous change to do this (f96dc73b) only skipped individually
named symlinks, not symlinks inside of a directory that was being
pulled.

This patch ensures that we read any error response from the server if the
server closes the connection. Unfortunately, that's not sufficient to ensure
that we always see the server's error message --- sometimes the data just
gets thrown away because we keep writing without reading. Setting SO_LINGER
avoids this.

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.

I put the conditional in the wrong place, not realizing that even the
old shell system allowed one 'argument'.
