netbsd dirent.h, import sys/sys *.h, mfs cleanup

. add all sys/sys headers not already present to help compiling
	. take netbsd dirent.h and struct dirent; main result is
	  introducing d_type and d_namlen that have to be set by getdents()
	  in all FS code implementing it
	. d_off is gone
	. alignment of the struct has become 8 bytes instead of 4
	. remove _MAX_BLOCK_SIZE, _MIN_BLOCK_SIZE, _STATIC_BLOCK_SIZE
	. libminlib: cleanup unused yet duplicate code
	. mfs: throw out the long-broken v1, v2 support
	. new test for dirent contents filled by getdents()

* normal kernel build does not rebuild it (it's merely included whole-
* sale from i386/bioscall.s)

* Also, note that the GEXTBIOSDATA_SEL selector is special, as it maps
* to the value 0x0040 (when created as a KPL global selector). Some
* BIOSes reference the extended BIOS data area at segment 0040 in a non
* relocatable fashion (even when in protected mode); mapping the zero page
* via the GEXTBIOSDATA_SEL allows these buggy BIOSes to continue to work
* under NetBSD.
*
