637f688f0d PM: Convert K&R C -> ANSI C
Aditionally this removes all trailing whitespaces in pm server code
using: sed -i 's/[[:space:]]*$//' *.c

d991a2bea3 Retire sysuname(2), synchronize sys/utsname.h
Now that uname(3) uses sysctl(2), we no longer need sysuname(2).
Backward compatibility is retained for old statically linked
binaries for a short while.

Also remove the now-obsolete MINIX3-specific "arch" field from the
utsname structure.  While this is an ABI break at the libc level,
it should pose no problems in practice, because:

- statically linked programs (i.e., all of the base system) are not
  affected, as they will use headers synchronized with libc;
- the structure is getting smaller, thus, older dynamically linked
  programs (typically in pkgsrc) using the new libc will end up with
  garbage in the "arch" field, but it is unlikely they will use this
  field anyway, since it was specific to MINIX3;
- new dynamically linked programs using an old libc could end up with
  memory corruption, but this is not a scenario that is expected to
  occur in the first place - certainly not with programs from pkgsrc.

This updates:
 - LLVM to 3.6.1
 - GCC to GCC 5.1
 - Replace minix/commands/zdump with usr.bin/zdump
 - external/bsd/libelf has moved to /external/bsd/elftoolchain/
 - Import ctwm
 - Drop sprintf from libminc

29346ab043 PM: add support for wait4(2)
This patch adds support for the wait4 system call, and with that the
wait3 call as well.  The implementation is absolutely minimal: only
user and system times of the exited child are returned (with all other
rusage fields left zero), and there is no support for tracers.  Still,
this should cover the main use cases of wait4.

bc2d75fa05 Rework getrusage(2) infrastructure
- the userland call is now made to PM only, and PM relays the call to
  other servers as appropriate; this is an ABI change that will
  ultimately allow us to add proper support for wait3() and the like;
  for the moment there is backward compatibility;
- the getrusage-specific kernel subcall has been removed, as it
  provided only redundant functionality, and did not provide the means
  to be extended correctly in the future - namely, allowing the kernel
  to return different values depending on whether resource usage of
  the caller (self) or its children was requested;
- VM is now told whether resource usage of the caller (self) or its
  children is requested, and it refrains from filling in wrong values
  for information it does not have;
- VM now uses the correct unit for the ru_maxrss values;
- VFS is cut out of the loop entirely, since it does not provide any
  values at the moment; a comment explains how it should be readded.

f737eea636 svrctl(2) update
- synchronize request type with ioctl by making it unsigned long;
- unbreak VFS requests, as they were being sent to PM;
- use proper ioctl direction flags (and new numbers) for requests;
- remove some needless header inclusions;
- svrctl is in libc, make its message name reflect this;
- keep backward compatibility: svrctl is part of the userland ABI.
