Move internal functions.

This patch moves a few internal functions from definitions.mk
to two new files named definitions-utils.mk and definitions-host.mk.

Functions in definitions-utils.mk should be generic and not rely
on any global variables / environment variables / the file system.
This makes them trivial to test properly.

Functions in definitions-host.mk depends on the value of HOST_OS
and are really used to generate shell commands during the build.

definitions.mk still contains functions related to the build, e.g.
the module database.

+ Add three new utility functions, and corresponding tests:

   filter-by
   filter-out-by
   find-first

  They'll be used by functions defined in later patches.
