Retain compatibility of EVP_DigestInit() and EVP_DigestFinal()
with existing code.

Modify library to use digest *_ex() functions.

'Handshake' protocol structures are kept in memory, including
'msg_type' and 'length'.

(This is in preparation of future support for callbacks that get to
peek at handshake messages and the like.)

a few items however, most of the details are deferred to the
crypto/engine/README file.

1. if there are several symbols with the same entry number, sort those
   symbols in ASCII order.
2. Do not stop reading the header files when "BEGIN ERROR CODES" is
   found, since mkerr.pl will add a function declaration after that
   comment.  Instead, trigger on "Error codes for the \w+ function",
   which is the actual start of the error code macros.

Additionally, a few more debugging printouts that helped.

Some '*)' apparently should be '+)' as the changes do not apply

Add CRL utility functions to allow CRLs to be
built up without accessing structures directly.

Update ca.c to use new functions.

Fix ca.c so it now build CRLs correctly again.

His comments are:

1) Changes all references for `True64' to be `Tru64', which is the correct
spelling for the OS name.

2) Makes `alpha-cc' be the same as `alpha164-cc', and adds an `alphaold-cc'
entry that is the same as the previous `alpha-cc'.  The reason is that most
people these days are using the newer compiler, so it should be the default.

3) Adds a bit of commentary to Configure, regarding the name changes of
the OS over the years, so it's not so confusing to people that haven't been
with the OS for a while.

4) Adds an `alpha-cc-rpath' target (which is *not* selected automatically
by Configure under any circumstance) that builds an RPATH into the
shared libraries.  This is explained in the comment in Configure.  It's
very very useful for people that want it, and people that don't want it
just shouldn't choose that target.

5) Adds the `-pthread' flag as the best way to get POSIX thread support
from the newer compiler.

6) Updates the Makefile targets, so that when the `alpha164-cc', `alpha-cc',
or `alpha-cc-rpath' target is what Configure is set to use, it uses a Makefile
target that includes the `-msym' option when building the shared library.
This is a performance enhancement.

7) Updates `config' so that if it detects you're running version 4 or 5
of the OS, it automatically selects `alpha-cc', but uses `alphaold-cc'
for versions 1-3 of the OS.

8) Updates the comment in opensslv.h, fixing both the OS name typo and
adding a reference to IRIX 6.x, since the shared library semantics are
virtually identical there.
