Support for dynamically linked executables, also build shared versions of base system libraries

Remove the use of Intel segments altogether, giving a performance boost while context switching. Rely exclusively on page tables. (more info)

Added support for SYSENTER/SYSCALL based system kernel calls, a significant performance improvement. (more info)

Full new clean updated NetBSD build system import. build.sh is supported, allowing crossbuilding MINIX 3.

Imported or upgraded many userland utilities and libraries from NetBSD: libc, lorder, join, mtree, tsort, cksum, kill, xinstall, du, libutil, tic, postinstall, flex, zlib, bsdtar, ls, sort, cat, echo, pax, file, mktemp, libc,csu, curses, byacc, tput, test, ln, nvi,ctags, infocomp, nbperf, make, m4, bzip2, libcrypt, printf, passwd, make, ed, nawk, expr, pwd.

DDEKIT support (support for USB keyboards, mice and mass storage).

Generalization of the TTY driver.

Small and large cleanup represented by retiring MINIXisms such as nonsymbolic rootdev, dev2name, checkhier, badblocks, readall, BIOS_SEG and umap_bios, bios_wini, C macros as _ANSI, _CONST, _VOLATILE, _SIZET, _ARGS, _VOID, PUBLIC, PRIVATE and FORWARD, _PROTOTYPE.

VM: Generalized munmap (boot time ramdisk is now freed, saving memory).

VFS interaction with drivers is fully asynchronous, making VFS immune to uncooperative drivers. (more info)
