[perl #84358] Removing AutoLoader from DynaLoader

DynaLoader currently uses Autoloader. This was an optimization going
back to perl 5.000 in 1994. However, this implementation detail leaks in
a rather troublesome way.

DynaLoader is used by subclassing it. Because of this, when you call
some undefined method on an instance of any class that derives from
DynaLoader (directly or indirectly) you do not get this error message:

    Can't locate object method "undefined_method" via package "Foo"

But this rather cryptic error:

    Can't locate auto/Foo/undefined_m.al in @INC (@INC contains:
/etc/perl /usr/local/lib/perl/5.10.0 /usr/local/share/perl/5.10.0
/usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10
/usr/local/lib/site_perl .)

This is totally incomprehensible for anyone who isn't familiar with
what's going on. It was rather a premature optimization anyway if you
ask me, on my machine it's just 66 non-empty lines of code that are
being autoloaded.

Therefore, I think AutoLoader should be removed from DynaLoader.

Move dprofpp from utils/ to ext/Devel-DProf/bin

This way the script can easily be part of the CPAN distribution, where
ExtUtils::MakeMaker will do its shebang munging.

In the core, we still have utils/dprofpp.PL, which also does shebang munging and
takes care of creating `dprofpp.com' instead of just `dprofpp' on VMS, which
ExtUtils::MakeMaker doesn't seem to be up to yet.

To make this work, some things had to be moved from script-generation-time to
run-time:

 * location of the stty binary
   This is probably better for binary perl distributions anyway

 * Devel::DProf version detection
   This is needed for `dprofpp -V'. The version number used to be copied into
   the script, but is now determined by actually loading Devel::DProf.

   In order for this to work it's necessary to be able to load DProf without
   causing profiling to start. For that, starting of the profiler has been moved
   to `import', causing

     require Devel::DProf;

   to not trigger it anymore, while

     use Devel::DProf;

increases read and write performance in the neighborhood of 25%
to 50% when using the default layers of perlio on top of unix.

The only situation without a noticeable performance benefit so
far appears to be when physical I/O is so slow that it dwarfs
any savings from the reduction in layer shuffling, but there
is also no performance penalty in this case.

not set such a value without good reason.

fix many s/// tainting bugs

This is a re-implementation of the tainting code in pp_subst and
pp_substcont. Although this fixes many bugs, because its a de-novo rewrite
of the tainting parts of the code in those two functions, it's quite
possible that it breaks some existing tainting behaviour. It doesn't break
any existing tests, although it turns out that this area was severely
under-tested anyway.

The main bugs that this commit fixes are as follows, where:

T = a tainted value
L = pattern tainted by locale (e.g. use locale; s/\w//)
Happens both with and without 'use re taint' unless specified.
Happens with all modifiers (/g, /r etc) unless explicitly mentioned.

    $1 unexpectedly untainted:
s/T//
T =~ s///            under use re 'taint'

     original string unexpectedly untainted:
s/L//,  s/L//g

    return value unexpectedly untainted:
T =~ s///g           under no re 'taint'
s/L//g,  s/L//r

    return value unexpectedly tainted:
s/T//
s//T/r               under no re 'taint'
T =~ s///            under use re 'taint'
s//T/                under use re 'taint'

Also, with /ge, the original string becomes tainted as soon as possible
(usually in the second entry to the /e code block) rather than only at the
end, in code like

    $orig =~ s/T/...code.../ge

The rationale behind the taintedness of the return value of s/// (in the
non /r case), is that a boolean value shouldn't be tainted. This
corresponds to the general perl tainting policy that boolean ops don't
return tainted values. On the other hand,  when it returns an integer
(number of matches), that should be tainted.

A couple of note about the old tainting code this replaces: firstly, several
occurrences of the following were NOOPs, since rxtainted was U8 and the bit
being ored was > 256:

    rxtainted |= RX_MATCH_TAINTED(rx)

secondly, removing a whole bunch of the following didn't make any
existing tests fail:

    TAINT_IF(rxtainted & 1);
