perl5.000 patch.0k: MakeMaker 4.06 and to fix minor portability and build problems reported even after patches 0a through 0j

MakeMaker 4.06 allows you to build extensions away from the source
tree with either static or dynamic loading.

In a rare act of prescience, I've also fixed some un-reported bugs.
Specifically, there were several places where Configure said you could
specify things using ~name notation, but, in fact, you couldn't.

In detail, here's what's included:

Configure
        Check I_SYS_TYPES for x2p/a2p.h
        Improve and generalize $osvers detection for DEC Alpha
    (now will work even for osvers > 3.)
        No longer override hint-file setting of $archname.
        Don't tell users ~name is ok for Dynamic loading file.  It's not.

MANIFEST
MANIFEST.new
        Updated.

Makefile.SH
        Some trailing ' ' removed from lines.
        New target lib/ExtUtils/Miniperl.pm built.  This stashes away
    miniperlmain.c in the library so new static extensions can be
    built away from the source tree.
        Minor cleanup.

U/Oldconfig.pat.2
        This is a patch to be applied against dist-PL 50 to upgrade
    the DEC OSF/1 version detection.

U/archlib.U
        Preserve previous value for $archname.  Otherwise this is
    identical to the unit in dist-PL 50.

U/dlsrc.U
        Users may not use ~name notation to find the dynamic loading
    module.  (Back in early alpha days they could, but that hasn't
    worked since the DynaLoader module was introduced.

config.H
        Updated.

config_h.SH
        Updated.

hints/dec_osf.sh
        Updated.  Simplified.  Don't use ld -no_archive (at least as
    the default).  It only worked because some versions *ignored* it.

hints/mpeix.sh
        Add a few comments.  I should have added more.

hints/next_3_0.sh
        New hint file from Kevin White <klwhite@magnus.acs.ohio-state.edu>

hints/ultrix_4.sh
        Separate out flags not appropriate for gcc.

installperl
        Install sperl.o.

lib/ExtUtils/MakeMaker.pm
        Upgraded from 4.03 to 4.06.  Many improvements.  Now possible
        to build and install new extensions outside the source tree,
        for both static and dynamic loading.

lib/File/Path.pm
        New.  Creates or removes a series of directories

makeaperl
        New utility to create a new perl binary from static extensions

minimod.PL
        New.  minimod.PL writes the contents of miniperlmain.c into the
        module ExtUtils::Miniperl for later perusal (when the perl
        source is deleted)

perl.c
        ARCHLIB and PRIVLIB changed to ARCHLIB_EXP and PRIVLIB_EXP,
        since perl is not prepared to deal with ~name expansion.  The
        _EXP variables are pre-expanded by Configure.

proto.h
        NeXt 3.0 couldn't handle the  #ifdef __attribute line.
    It said 'illegal #ifdef'.

vms/config.vms
        s/ARCHLIB/ARCHLIB_EXP/;
        s/PRIVLIB/PRIVLIB_EXP/;
        Add in I_SYS_STAT and I_SYS_TYPES, since the source now looks
    for them.

vms/ext/MM_VMS.pm
        New file.

x2p/a2p.h
        Include <sys/types.h>
