Make unixify unescape filespecs already in Unix format.

Sometimes filename components get pasted together in ways that put
a component with caret escapes proper to Extended Filename Syntax
(EFS) for native filespecs into a Unix-format filespec. An example
would be /a/b/foo^_bar, where the '^_' sequence indicates a space
in a native filespec but is technically invalid in a Unix
filespec.

But it doesn't really cost much more to remove the escapes since
we're copying the whole string anyway, so go ahead and do that.
This could theoretically cause trouble if we get Unix-format paths
that have literal carets in them, but that theoretical trouble is
currently less troubling than the practical trouble that crops up
various places in the test suite if we don't do this.
Help ExtUtils::Manifest deal with VMS extended filespecs.

For one thing, if we're cleaning up filenames, lets put that code
in the sub called 'clean_up_filename' rather than in manifind.  And
since the language of the MANIFEST is really Unix-format filespecs,
convert to those.  This becomes especially important in handling
extended filespecs because unixification also unescapes escaped
characters.
Make readdir on VMS only unixify when asked.

We've been making our home-grown readdir implementation convert
all its results to Unix format since a096370a74e8.  Since readdir
returns relative paths, the usual volume and directory syntax
differences that distinguish VMS and Unix paths don't really apply.

But what does apply is whether the escaping of extended characters
is passed through or removed, and converting to Unix syntax removes
those escapes.  In order to enable extended filename syntax, though,
we're really going to need the escapes.  For example, rmdir will
not be able to remove a directory foo.bar if it's referred to as
[.foo.bar] because a dot is the traditional directory delimiter.
The directory needs to be specified as [.foo^.bar] for rmdir to
delete it successfully.

So make readdir return filespecs in native format unless explicitly
requested to report all filenames in Unix format.
Make extended filename syntax the default on VMS.

This feature has been available for over a decade but is still not
the default for the CRTL.  It seems time to make it the default
for Perl.  It means that directory names can have dots in them,
and filenames can contain multiple dots as well as spaces and
generally characters from the top row of the keyboard while the
shift key is held down.

Filenames with native syntax must escape characters in the so-called
extended character set with a caret ("^"), but filenames in Unix
syntax must not have the escapes.  Conversions between native and
Unix syntax will, respectively, add and remove these escapes.

Supporting Unicode in filenames depends on this feature but has
not yet been investigated.
List files excluded from Config::Perl::V
Update File::Temp layout

The latest tarball has moved Temp.pm into a lib/ folder, so we may as well
do likewise to keep Maintainers.pl happy. Also correct the tarball filename
listed there.
t/porting/diag.t now reads files from MANIFEST, instead of scanning the disk.

This does less work, and avoids both files duplicated by the build system,
and false positives due to temporary files left by developers.
Extend t/porting/diag.t to cover various other C-like files.

Specifically C++ source, and files related to perly.y and x2p/a2p.y
This catches an error in an XS module embedded into the (moribund) Symbian
port, which we need to skip.
Extend t/porting/diag.t to cover code in DynaLoader.

This seems a reasonable extension to cover, as it's arguably part of the
core, because it has to be linked into the perl executable, and handled
differently from everything else, even "static" extensions.

This reveals that DynaLoader can generate a previously undocumented warning,
so document this.
