Provide backwards-compatiblity for functions, macros and include

When it's the last item that is removed int_thread_hash == hash and we would
still call int_thread_release(&hash) while hash is already freed.  So
int_thread_release would compare that dangling pointer to NULL which is
undefined behaviour.  Instead do already what int_thread_release() would do,
and make the call do nothing instead.

Because the default error macro generator assumes the header file with
error macros is in include/openssl and therefore generates a C file
with error texts that include <openssl/{name}.h>, we need to generate
the error macros and texts for CT separately, since the CT module
doesn't follow the default criteria.

We had updates of certain header files in both Makefile.org and the
Makefile in the directory the header file lived in.  This is error
prone and also sometimes generates slightly different results (usually
just a comment that differs) depending on which way the update was
done.

This removes the file update targets from the top level Makefile, adds
an update: target in all Makefiles and has it depend on the depend: or
local_depend: targets, whichever is appropriate, so we don't get a
double run through the whole file tree.

There are header files in crypto/ that are used by a number of crypto/

affected source code and Makefiles.

The header files that got moved are:

crypto/cryptolib.h

For a local variable:
        TYPE *p;
Allocations like this are "risky":
        p = OPENSSL_malloc(sizeof(TYPE));
if the type of p changes, and the malloc call isn't updated, you
could get memory corruption.  Instead do this:
        p = OPENSSL_malloc(sizeof(*p));
Also fixed a few memset() calls that I noticed while doing this.

Remove ERR_[gs]et_implementation as they were not undocumented and
useless (the data structure was opaque).

Halve the number of lock/unlock calls in almost all ERR_
functions by letting the caller of get_hash or int_thread_set
able to lock.  Very useful when looping, such as adding errors,
or when getting the hash and immediately doing a lookup on it.

With no more symlinks, there's no need for those variables, or the links
target.  This also goes for all install: and uninstall: targets that do
nothing but copy $(EXHEADER) files, since that's now taken care of by the
top Makefile.

Also, removed METHTEST from test/Makefile.  It looks like an old test that's
forgotten...

Rather than making include/openssl/foo.h a symlink to

once and for all.
