jackpal@google.com e060b66a3e Add _android files for building DartVM on Android
Split directory_posix -> directory_(android|linux|macos)
  This allows us to cleanly make Android-specific changes to
  directory_android.cc

Copy all _linux files to _android files and edit as needed to account
for the differences between Linux and Android:

 + getcwd(0, NULL) doesn't work on Android, have to emulate
 + Android doesn't have a '/tmp' directory, have to emulate
 + Android doesn't provide mkdtemp(), have to emulate.
 + Small differences in the available system include files.
 + Use pthread_cond_timedwait_monotonic instead of
   pthread_condattr_setclock
