1facb0487c libc: add posix_spawn family of functions
The implementation is taken from newlib (BSD licensed) and test84 is based
on NetBSD's t_spawn.c

da21d85025 Add PTYFS, Unix98 pseudo terminal support
This patch adds support for Unix98 pseudo terminals, that is,
posix_openpt(3), grantpt(3), unlockpt(3), /dev/ptmx, and /dev/pts/.
The latter is implemented with a new pseudo file system, PTYFS.

In effect, this patch adds secure support for unprivileged pseudo
terminal allocation, allowing programs such as tmux(1) to be used by
non-root users as well.  Test77 has been extended with new tests, and
no longer needs to run as root.

The new functionality is optional.  To revert to the old behavior,
remove the "ptyfs" entry from /etc/fstab.

Technical nodes:

o The reason for not implementing the NetBSD /dev/ptm approach is that
  implementing the corresponding ioctl (TIOCPTMGET) would require
  adding a number of extremely hairy exceptions to VFS, including the
  PTY driver having to create new file descriptors for its own device
  nodes.

o PTYFS is required for Unix98 PTYs in order to avoid that the PTY
  driver has to be aware of old-style PTY naming schemes and even has
  to call chmod(2) on a disk-backed file system.  PTY cannot be its
  own PTYFS since a character driver may currently not also be a file
  system.  However, PTYFS may be subsumed into a DEVFS in the future.

o The Unix98 PTY behavior differs somewhat from NetBSD's, in that
  slave nodes are created on ptyfs only upon the first call to
  grantpt(3).  This approach obviates the need to revoke access as
  part of the grantpt(3) call.

o Shutting down PTY may leave slave nodes on PTYFS, but once PTY is
  restarted, these leftover slave nodes will be removed before they
  create a security risk.  Unmounting PTYFS will make existing PTY
  slaves permanently unavailable, and absence of PTYFS will block
  allocation of new Unix98 PTYs until PTYFS is (re)mounted.

22840dea11 libfsdriver: preinitialize stat.st_ino
The stat.st_ino field must always be filled with the inode number
given as part of the fdr_stat request anyway, so libfsdriver can
simply fill in the number and allow the file system not to bother.

af4345b097 isofs: do not link against libc
This change requires a small patch to libc, in order to avoid that
libminc has to pull in a large chunk of libc just for mktime(3).

5ae1a533c7 ARM: can build with llvm, switch to EABI
. bitcode fixes
	. switch to compiler-rt instead of netbsd libc functions
	  or libgcc for support functions for both x86 and arm
	. minor build fixes
	. allow  build with llvm without crossbuilding llvm itself
	. can now build minix/arm using llvm and eabi - without C++
	  support for now (hence crossbuilding llvm itself is turned off
	  for minix/arm)

89c9de7d09 Add libfsdriver: a library to drive file systems
This library provides new abstractions for the upper (VFS) side of
file system services, and should be used for all file system service
implementations from now on.  It provides the following functionality:

  - a function call table abstraction, hiding the details of the
    VFS-FS protocol with simple parameters;
  - a (currently limited) number of per-function steps required for
    all file system implementations, such as copying in and out path
    names and result buffers;
  - a default implementation for multicomponent path lookups, such
    that the file system merely has to implement resolution of single
    components at a time;
  - an abstraction for copying data from and to the file system, which
    allows transparent intraprocess copying as required for the lookup
    implementation;
  - a set of functions to simplify getdents implementations.

The message loop provided by the library is currently for use by
single-threaded file system implementations only.  Multithreaded file
system services may use the more low-level message processing
functionality.

Protocol-level optimizations such as including names in protocol
messages may be hidden entirely in this library.  In addition, in the
future, the lookup implementation may be replaced by a single-
component lookup VFS/FS protocol request as part of a VFS name cache
implementation; this, too, can be hidden entirely in this library.

31b808b8fa Drop minix-malloc & friends
Known limitations:
 - comment for now testisofs, as iso9660fs is known to be broken.

Benefits:
 - near 3x speed improvement on C++ code compilation, bringing down
   make build to from 44min down to 21min.

 - Allows for X applications to work properly, which should be available
   in near-term future through pkgsrc for 3.3.0.

43d985050c Use one message type for all BDEV request.
There are missing field assignements, and/or messsages being re-used
without re-initializations, which allows for fields to be implicitly
forwarded.

This prevents me from creating per request message types, as I can't
spend currently any more time debugging this issue.
