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. Conflicts: README config gem/ltn012.tex makefile src/makefile src/options.c src/options.h src/tcp.c src/usocket.c
