Add ASYNCerr support to give some meaningful error message in the event of
a failure.

The ASYNC null implementation has not kept pace with the rest of the async
development and so was failing to compile.

Where we can we should use longjmp and setjmp in preference to swapcontext/
setcontext as they seem to be more performant.

Create a "null" async implementation for platforms that lack support. This
just does nothing when called and therefore performs synchronously.

Provides support for running asynchronous jobs. Currently this is completely
stand alone. Future commits will integrate this into libssl and s_server/
s_client. An asynchronous capable engine will be required to see any benefit
from this capability.

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.

With no more symlinks, there's no need for those variables, or the links

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...

This gives shorter output both if ranlib fails and if

This means that all Makefiles will have $(TOP) as one of the include

sure they are available in opensslconf.h, by giving them names starting
with "OPENSSL_" to avoid conflicts with other packages and by making
sure e_os2.h will cover all platform-specific cases together with
opensslconf.h.

I've checked fairly well that nothing breaks with this (apart from
external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
change would be a good thing.

acceptable, since all that happens if it fails is a library with

Also, "make update" has added some missing functions to libeay.num,
updated the TABLE for the alpha changes, and updated thousands of
dependancies that have changed from recent commits.

in cryptlib.h (which is often included as "../cryptlib.h"), then the
question remains relative to which directory this is to be interpreted.
gcc went one further directory up, as intended; but makedepend thinks
differently, and so probably do some C compilers.  So the ../ must go away;
thus e_os.h goes back into include/openssl (but I now use
#include "openssl/e_os.h" instead of <openssl/e_os.h> to make the point) --
and we have another huge bunch of dependency changes.  Argh.

There were problems with putting e_os.h just into the top directory,
because the test programs are compiled within test/ in the "standard"
case in in their original directories in the makefile.one case;
and in the latter symlinks may not be available.
