darwin: do not set DYLD_LIBRARY_PATH on tests
#2: bootstrap config.inc via config.mak

new configure script which calls make -f config.mak,
which creates config.inc in sync with core/config.h.
Vastly improved make time
Silence test, adjust readme, fix darwin loadext/dll mixup
.gitgnore generated config.inc
Merge remote-tracking branch 'origin/master' into p2

Fixed conflicts:
	Makefile
Changed config.mak for p2
