Add 'emulator' launcher program.

This patch renames the current ARM-specific emulator binary to 'emulator-arm'
and introduces a new tiny (less than 20KB) 'emulator' launcher program.

The role of 'emulator' is to launch either 'emulator-arm' or 'emulator-x86'
based on the target AVD or platform build being used.

This program will be replaced in the future by what is currently known
as 'emulator-ui', but is a good placeholder until this work is completed.

+ Move some utility functions from android/avd/info.[hc] to
  android/avd/util.[hc] so that 'emulator' can use them directly.

IMPORTANT: For platform builds, the target architecture is detected
           automatically by parsing the build.prop file.

           For SDK AVDs however, there is no easy way to determine the
           target architecture, so the patch adds a new hw.cpu.arch
           property which can have value 'arm' or 'x86'
