Use linenoise to add simple editing and history to the Android shell.

The linenoise library is from http://github.com/antirez/linenoise

This patch also disables command-line editing and history from adb. The
adb implementation was shadowing the Android shell's implementation.

The adb implementation was also shadowing the editing and history
implementation in alternative shells such as BusyBox's ash.
