Correct misspelled VXWORKS macros.
Add VXWORKS identifying macros to e_os2.h.
Add required inclusions and mappings for VxWorks in e_os.h.
A few small modifications to make OpenSSL build and work on VxWorks.
PR: 253, except for the  change that was handled in an earlier
         commit, and a request for easy build of just parts of OpenSSL.

New cofiguration for Unixwre and SCO,with slightly better granularity.  Contributed by Tim Rice <tim@multitalents.net>

missed any.

This compiles and runs on Linux, and external applications have no
problems with it.  The definite test will be to build this on VMS.

during connect() and other calls. First seen on Unixware-7.

Unify access to EGD-socket for all RAND_egd_*() methods.

OCSP basic response verify. Very incomplete
but will verify the signatures on a response
and locate the signers certifcate.

Still needs to implement a proper OCSP certificate
verify.

Fix warning in RAND_egd().

only queried when the /dev/[u]random devices did not return enough
entropy. Only the amount of entropy missing to reach the required minimum
is queried, as EGD may be drained.
Queried locations are: /etc/entropy, /var/run/egd-pool

The message to everyone is "Do not hack OpenSSL when stressed"...

the RANDEGD environment variable.

"standard" refers to the C language, probably there's also some
standard that defines memory.h).

the second argument to be of type ``struct sockaddr *''.

Avoid enabled 'assert()' in production library.

used anywhere in OpenSSL, but might be used by libdes applications.

Never use des_set_key (it depends on the global variable des_check_key),
but usually des_set_key_unchecked.
Only destest.c bothered to look at the return values of des_set_key,
but it did not set des_check_key -- if it had done so,
most checks would have failed because of wrong parity and
because of weak keys.

(meaning pointer to char) to des_cblock * (meaning pointer to
array with 8 char elements), which allows the compiler to
do more typechecking.  (The changed argument types were of type
des_cblock * back in SSLeay, and a lot of ugly casts were
used then to turn them into pointers to elements; but it can be
done without those casts.)

Introduce new type const_des_cblock -- before, the pointers rather
than the elements pointed to were declared const, and for
some reason gcc did not complain about this (but some other
compilers did).
