gmp: Bring back version 4.2.1 (LGPL 2.1+)

gmp 4.2.1 was removed in f181c6ce8b apparently accidentally: It
was not noticed that 4.2.1 is LGPL 2.1 (and not GPL) so provides
a useful alternative to the newer "GPLv2 | LGPLv3" version.

* Reintroduce 4.2.1. The source includes files that are GPL but the
  library package is LGPL 2.1+
* Also reintroduce the two patches removed in f181c6ce8b.
* Refactor gmp.inc: gmp 6.0.0 build should not be affected in any way.
* Update 6.0.0 license from "GPLv2 | LGPLv3" to "GPLv2+ | LGPLv3+".
