Commit d32f5d87

 added a 'goto end;' statement
at the end of the code block for the 'end' label.  Fortunately, it was after a
return statement, so no infinite loop occurred, but it is still dead code.

Remove the extra goto statement as cleanup.

In the case of generating a file like this:

    GENERATE[foo.S]=mkfoo.pl arg1 arg2

the 'mkfoo.pl' generator itself might need to include other files,
such as perl modules within our source tree.  We can reuse already
existing syntax for it, like this:

    INCLUDE[mkfoo.pl]=module/path

or:

    DEPEND[mkfoo.pl]=modules/mymodule.pm

This change implements the support for such constructs, and for the
DEPEND statement, for any value that indicates a perl module (.pm
file), it will automatically infer an INCLUDE statement for its
directory, just like it does for C header files, so you won't have do
write this:

    DEPEND[mkfoo.pl]=modules/mymodule.pm
    INCLUDE[mkfoo.pl]=modules

It is up to the caller of SSL_dane_tlsa_add() to take appropriate
action when no records are added successfully or adding some records
triggers an internal error (negative return value).

With this change the caller can continue with PKIX if desired when
none of the TLSA records are usable, or take some appropriate action
if DANE is required.

Also fixed the internal ssl_dane_dup() function to properly initialize
the TLSA RR stack in the target SSL handle.  Errors in ssl_dane_dup()
are no longer ignored.

If we fail halfway through constructing the peer_tmp EVP_PKEY but we have
already stored it in s->s3->peer_tmp then if anything tries to use it then
it will likely fail. This was causing s_client to core dump in the
sslskewith0p test. s_client was trying to print out the connection
parameters that it had negotiated so far. Arguably s_client should not do
that if the connection has failed...but given it is existing functionality
it's easier to fix libssl.

Our main development platforms are of the Unix family, which doesn't
have the same strictness regarding a shared library being consistent
with the contents of the ld script (.map file, on Linux and Solaris)
as Windows is with the contents of the .def file or VMS is with the
linker symb_vector option.

To eliminate surprises, we therefore need to make sure to check that
the contents of the .map file is matched with the shared library, at
least to check that the shared library isn't missing any symbols that
should be present.

This test isn't absolutely perfect, as it will only check the symbols
that would be present on Linux / Solaris and will therefore miss those
that would only appear on Windows or VMS.  On the other hand, those
platform specific are few and far apart in time, so it's not likely
they will pose a problem.
