Junjie Mao 647aee6e34 scripts: introduce .config/config.h generators
This patch introduces some scripts that takes a Kconfig script and generates
.config or config.h. These scripts are general and can be used by the
hypervisor, dm, tools, etc. as long as proper make targets are added.

Note: Kconfiglib by Ulf Magnusson is ISC licensed.

v4 -> v5:

    * Add minimalconfig which creates a defconfig by minimizing a given .config.

v3 -> v4:

    * silentoldconfig now properly generate a .config if an old one does not
      exist.

v2 -> v3:

    * Add license info and the permission notice of Kconfiglib.
    * Mention the input Kconfig in the script descriptions.

v1 -> v2:

    * Drop kconfiglib.py. The getting started guide will be updated accordingly
      and dependency checks will be added to Makefile in the following patches.
