These two request are handled by the same function in some FSes, which

afe5cecd7f Stub for setpgid
This implements a near noop setpgid, unless the use is one equivalent
to setsid, in which case it will behave as such.

Also activates setpgrp, which is implemented in terms of setpgid.

78cfc9712b Prefix libc (u)mount with minix_
The goal is to prevent a name collision with the expected mount/umount
function signatures, if we decide one day to allow any application
using those to work on MINIX.

At this moment the caller has to start the required services, but if we
implement that logic inside the mount/unmout function, this would allow
any application to call those function successfully.

By renaming those now, we prevent a possible ABI break in the future.

193733f9e2 Hide SO_PASSCRED and SO_PEERCRED by default.
This cause in some software to assume we are linux, as this is rightly
only used there.

By default hide it behind _MINIX_SYSTEM, until we have removed traces
of it from getpeereid/[gs]etsocketopt and replaced it by the NetBSD
mechanism.

69b8ce6ab2 x86:ensure that getcontext will return 0.
The setcontext method did not alway set the return value to 0 after
restoring the desired context. Specially When calling setcontext with
the _UC_IGNSIGM and the _UC_IGNFPU flags the return value would be non
zero.

0b79eac642 mmap: accept non-PROT_WRITE MAP_SHARED mappings
Currently we don't accept writable file mmap()s, as there is no
system in place to guarantee dirty buffers would make it back to
disk. But we can actually accept MAP_SHARED for PROT_READ mappings,
meaning the ranges aren't writable at all (and no private copy is
made as with MAP_PRIVATE), as it turns out a fairly large class of
usage.

	. fail writable MAP_SHARED mappings at runtime
	. reduces some minix-specific patches
	. lets binutils gold build on minix without further patching

	  behind _MINIX_SYSTEM to cleanly fix host tool build problems on
	  Minix (such as: NONE being defined and paddr_t being used but not
	  declared)
	. the similar definition _SYSTEM is unsuitable as it changes the
	  values of errno definitions

565f13088f make vfs & filesystems use failable copying
Change the kernel to add features to vircopy and safecopies so that
transparent copy fixing won't happen to avoid deadlocks, and such copies
fail with EFAULT.

Transparently making copying work from filesystems (as normally done by
the kernel & VM when copying fails because of missing/readonly memory)
is problematic as it can happen that, for file-mapped ranges, that that
same filesystem that is blocked on the copy request is needed to satisfy
the memory range, leading to deadlock. Dito for VFS itself, if done with
a blocking call.

This change makes the copying done from a filesystem fail in such cases
with EFAULT by VFS adding the CPF_TRY flag to the grants. If a FS call
fails with EFAULT, VFS will then request the range to be made available
to VM after the FS is unblocked, allowing it to be used to satisfy the
range if need be in another VFS thread.

Similarly, for datacopies that VFS itself does, it uses the failable
vircopy variant and callers use a wrapper that talk to VM if necessary
to get the copy to work.

	. kernel: add CPF_TRY flag to safecopies
	. kernel: only request writable ranges to VM for the
	  target buffer when copying fails
	. do copying in VFS TRY-first
	. some fixes in VM to build SANITYCHECK mode
	. add regression test for the cases where
	  - a FS system call needs memory mapped in a process that the
	    FS itself must map.
	  - such a range covers more than one file-mapped region.
	. add 'try' mode to vircopy, physcopy
	. add flags field to copy kernel call messages
	. if CP_FLAG_TRY is set, do not transparently try
	  to fix memory ranges
	. for use by VFS when accessing user buffers to avoid
	  deadlock
	. remove some obsolete backwards compatability assignments
        . VFS: let thread scheduling work for VM requests too
          Allows VFS to make calls to VM while suspending and resuming
          the currently running thread. Does currently not work for the
          main thread.
        . VM: add fix memory range call for use by VFS

d3d33afe9f Experimental pthread compatibility library
This patch adds pthread compatibility by using libmthread.

To use this with a program using pthreads, you have to replace
  #include <pthread>
with
  #define _MTHREADIFY_PTHREADS
  #include <minix/mthreads>

This also changes the initialization function to be a constructor, which
is implicitly called before the call to main. This allows for
conformance with pthreads, while not paying a high price by checking on
each mthread_* call whether the library has been initialized or not.

As mthread_init is now a constructor, it also has been set as static, and
relevent calls removed from programs using it.

- Fix for possible unset uid/gid in toproto
 - Fix for default mtree style
 - Update libelf
 - Importing libexecinfo
 - Resynchronize GCC, mpc, gmp, mpfr
 - build.sh: Replace params with show-params.
     This has been done as the make target has been renamed in the same
     way, while a new target named params has been added. This new
     target generates a file containing all the parameters, instead of
     printing it on the console.
 - Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)
     get getservbyport() out of the inner loop
