Merge branch 'git-sam' into diego-sam-mwild-integration

Conflicts in options.c were just due to independent small functions
being close to each other.

unix.c in mwild was broken, it wasn't using LUASOCKET_API.

serial.c needed luaL_reg renamed, and to use LUASOCKET_API.

makefile didn't respect standard DESTDIR and prefix makefile
variables, and didn't allow LUAV variable to select lua version to build
against.

I've tested the top-level install-both target builds and installs
against both lua5.1 and lua5.2, but not done further testing.
