perl5.000 patch.0i: fix glaring mistakes in patches a-h

This patch does the following things:
    1.  Fix various bonehead errors I introduced in patches a-g.
    2.  Incorporate MakeMaker changes to bring it up to version 4.01 (mostly).
    3.  Stick in things I forgot in patches a-g (e.g. AIX).
    4.  Some minor additional cleanup in x2p/ for even pickier compilers.
    5.  More hints updates (hpux and next).
    6.  Include newest dl_hpux.xs.

I didn't have time to
    1.  Fix the overlapping strcpy() in op.c
    2.  Restore h2xs to Larry's original design to process <>.
    3.  take out unnecessary "use Config" in installperl. 
    4.  Add in vms patches.

I forgot to
    [If I remembered what i forgot, I wouldn't have forgotten it. :]

I deliberately decided *not* to
    1.  Touch pod/*
    2.  deal with overloading


Specifically, here's what's included:

Configure
        Regenerated to be sure it's up-to-date. 

Makefile.SH
        Build extension libraries right into lib/auto/whatever.
        Don't set CCCDLFLAGS since we don't use it anyway.
        Take care to avoid modifying lib/Config.pm without reason
        Visit DynaLoader for  `make clean'.  (Previously only did
    so for `make realclean'.)
        @echo "Note that make realclean does not delete config.sh"
        Include config.h dependency.
  
U/i_db.U
config_h.SH
config.H
        Remove unwanted quotes around db_hashtype and db_prefixtype.
        
configpm
        Allow specification of alternate name for lib/Config.pm,
        so the makefile mv-if-diff trick saves needless re-making.
  
ext/DynaLoader/DynaLoader.pm
        Updated warning messages and comments.

ext/DynaLoader/dl_hpux.xs
        Updated to version 2.1.  Now uses bootstrap files.

ext/util/make_ext
        Explicitly use #!/bin/sh to start it up.  This is useful
    for testing make_ext.
        Improve & simplify Nested::Extension::Processing.
        More robust handling of `make clean'.

hints/hpux_9.sh
        Support both the bundled and unbundled compilers.
        
hints/next_3_2.sh
        Back to using -posix rather than POSIX_SOURCE.  And that only
    for ext/POSIX/POSIX.xs.
        
installperl
        Special ranlib treatment for NeXT, which gets confused about
    timestamps in libraries, even when you just copy the library.
        Supply missing '$' in samepath() function.
        
lib/AutoSplit.pm
        New parameters.

lib/ExtUtils/MakeMaker.pm
        Upgraded from 3.8 to 4.01.

lib/ExtUtils/xsubpp
        Documentation changed from man to pod.

lib/Getopt/Long.pm
        Avoid typo warning.
        Drop unused $optx.

lib/Text/Tabs.pm
        Fix package name.

makedepend.SH
        Explicitly start with $startsh.
        Catch cpp that prints # <stdin> instead of line numbers.

perl.h
        Fix bonehead mistake that ended up calling my_fmod even if
    not needed.

perl_exp.SH
        also add symbols from interp.sym

proto.h
        Delete 2 redundant prototypes (newBINOP and newUNOP).

util.c
        Add (char *) casts to unsigned char args to bcmp.

x2p/a2p.h
        Rearrange order of <string?.h> and bcopy & bzero stuff.
        Change a few function prototypes to void, to reflect actual
    usage.

x2p/a2py.c
        Change a few function types to void, to reflect actual usage.
      
x2p/handy.h
        Make *alloc declarations match those in x2p/util.c.

x2p/util.c
        Make *alloc declarations match those in x2p/handy.h.
  
x2p/walk.c
        Add a (Size_t) cast for comparison of 1 to the result of strlen(). 

Thanks to all who's work is included here.  Little of it is mine.
