Travis identified a problem with freeing the ex_data locks which wasn't
quite right in ff234405. Trying to fix it identified a further problem:
the ex_data locks are cleaned up by OPENSSL_cleanup(), which is called
explicitly by CRYPTO_mem_leaks(), but then later the BIO passed to
CRYPTO_mem_leaks() is freed. An attempt is then made to use the ex_data
lock already freed.

Some locks were not being properly cleaned up during close down.

After the final use of the thread_local_inits_st we should ensure it is
set to NULL, just in case OPENSSL_INIT_thread_stop gets called again and
it tries to use garbage.

This commit provides the basis and core code for an auto initialisation
and deinitialisation framework for libcrypto and libssl. The intention is
to remove the need (in many circumstances) to call explicit initialise and
deinitialise functions. Explicit initialisation will still be an option,
and if non-default initialisation is needed then it will be required.
Similarly for de-initialisation (although this will be a lot easier since
it will bring all de-initialisation into a single function).

Now that we're using templates, we should warn people not to edit the
resulting file.  We do it through util/dofile.pl, which is enhanced
with an option to tell what file it was called from.  We also change
the calls so the template files are on the command line instead of
being redirected through standard input.  That way, we can display
something like this (example taken from include/openssl/opensslconf.h):

    /* WARNING: do not edit! */
    /* Generated by Configure from include/openssl/opensslconf.h.in */

Very early version, doesn't do much yet, not even added to the build system.

GeneralizedTime. At several points PKIX specifies that GeneralizedTime can be
used but OpenSSL doesn't currently support it. This patch adds several files
and a bunch of functions.

Of interest is the ASN1_TIME structure and its related functions. At several
points certificates, CRLs et al specify that a time can be expressed as a
choice of UTCTime and GeneralizedTime. Currently OpenSSL interprets this
(wrongly) as UTCTime because GeneralizedTime isn't supported. The ASN1_TIME
stuff provides this functionality.

Still todo is to trace which cert and CRL points need an ASN1_TIME and modify
the utilities appropriately and of course fix all the bugs.

Note new OpenSSL copyright in the new file a_time.c. I didn't put it in
a_gentm.c because it is a minimally modified form a_utctm.c .

Since this adds new files and error codes you will need to do a 'make errors'
at the top level to add the new codes.
