adb shell escaping different from original Google version

[Michael Hofmann]

The parsing of the parameters to "adb shell" is different between the Ubuntu version and the original Google version. This change breaks all scripts that rely on the (weird) escaping of the original version.

Examples:

Behavior of Ubuntu version:
$ /usr/bin/adb shell echo "'hi'"
'hi'

Behavior of Google version (expected):
$ /opt/adt/sdk/platform-tools/adb shell echo "'hi'"
hi

Versions:

$ /usr/bin/adb -v
Android Debug Bridge version 1.0.32

$ /opt/adt/sdk/platform-tools/adb -v
Android Debug Bridge version 1.0.32
