x86_hdimage.sh: use nbstat from tooldir.
The syntax of the stat(1) command varies between Linux and FreeBSD.
This prevented `x86_hdimage.sh -i` from succeeding on FreeBSD 10.0.
The fix is to use the NetBSD stat from the tooldir for all systems.

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.

Replace wget with ftp as default in fetch scripts
This default is overriden by curl when it is available on the system.
This allows for the fetch script to work on MINIX systems without any
additions from PKGSRC, while requiring either a netbsd compatible ftp or
curl to be installed on other systems.

- Fix for default mtree style
- Update libelf

- Resynchronize GCC, mpc, gmp, mpfr

Remove some legacy support in rc scripts & some cleanup
* Remove support for the Poor Man fstab
* Remove checks for the missing ARCH kernel variable
* Remove .ashrc which is anyway only read once per login
* Cleanup PATH variable
- introduce new call numbers, names, and field aliases;
- initialize request messages to zero for all ABI calls;
- format callnr.h in the same way as com.h;
- redo call tables in both servers;
- remove param.h namespace pollution in the servers;
- make brk(2) go to VM directly, rather than through PM;
- remove obsolete BRK, UTIME, and WAIT calls;
- clean up path copying routine in VFS;
- move remaining system calls from libminlib to libc;
- correct some errno-related mistakes in libc routines.
For common calls, give servers unique call numbers
The getsysinfo(2), getrusage(2), and svrctl(2) calls used the same
call number to different services. Since we want to give each service
its own call number ranges, this is no longer tenable. This patch
introduces per-service call numbers for these calls.
Note that the remainder of the COMMON_ range is left intact, as these
the remaining requests in it are processed by SEF and thus server-
agnostic. The range should really be prefixed with SEF_ now.
- move system calls for use by services from libminlib into libsys;
- move srv_fork(2) and srv_kill(2) from RS and into libsys;
- replace getprocnr(2) with sef_self(3);
- rename previous getnprocnr(2) to getprocnr(2);
- clean up getepinfo(2);
- change all libsys calls that used _syscall to use _taskcall, so as
to avoid going through errno to pass errors; this is already how
most calls work anyway, and many of the calls previously using
_syscall were already assumed to return the actual error;
- initialize request messages to zero, for future compatibility
(note that this does not include PCI calls, which are in need of a
much bigger overhaul, nor kernel calls);
- clean up more of dead DS code as a side effect.
The original delayed reply functionality was there to support swapping
in processes as they are unblocked, but swap support is long gone.
These days, this code only incurs overhead and hides bugs.
When a process forks, VFS is informed on behalf of the child. This is
correct, because otherwise signals to the new child could get lost.
However, that means that the parent is not blocked from being killed
by a signal while the child is blocked on this VFS call. As a result,
by the time that the VFS reply comes in, the parent may already be
dead, and the child may thus have been assigned a new parent: INIT.
Previously, PM would blindly reply to the parent when the VFS reply
for the fork came in. Thus, it could end up sending a reply to INIT,
even though INIT did not issue the fork(2) call. This could end up
satisfying a different call from INIT (typically waitpid(2)) and then
cause an error when that other call was complete.
It would be possible to set VFS_CALL on both forking parent and child.
This patch instead adds a flag (NEW_PARENT) to note that a process's
parent has changed during a VFS call.
- introduce PROC_STOPPED flag, which tracks whether the process is
stopped on PROC_STOP in the kernel, rather than implicitly deriving
this from PM_SIG_PENDING;
- make the process resumption test based on current state rather than
state transitions;
- add and clarify several flag checks in the signal handling code;
- add test79 to test signal handling robustness.
