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.

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)

1dcfbcd173 Remove support for call profiling
The entire infrastructure relied on an ACK feature, and as such, it
has been broken for years now, with no easy way to repair it.

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.

69cba46141 libc: make ttyname(3) use devname(3)
There was an off-by-one in the old MINIX-specific implementation,
which caused ttyname(3) to fail at random. Since we now have a working
devname(3), there is no need for MINIX-specific code anymore here.
