323f289c48 Change all calls to low level digest routines in the library and
applications to use EVP. Add missing calls to HMAC_cleanup() and
don't assume HMAC_CTX can be copied using memcpy().

Note: this is almost identical to the patch submitted to openssl-dev
by Verdon Walker <VWalker@novell.com> except some redundant
EVP_add_digest_()/EVP_cleanup() calls were removed and some changes
made to avoid compiler warnings.

41d2a336ee e_os.h does not belong with the exported headers. Do not put it there
and make all files the depend on it include it without prefixing it
with openssl/.

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

bc36ee6227 Use new-style system-id macros everywhere possible. I hope I haven't
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.

cf1b7d9664 Make all configuration macros available for application by making
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.

d6ade7422a Looks like Win32 builds do not define THREADS. However, they're still
supporting threads, which means that th assertion is supperbly
dangerous, so make sure it's not compiled under Win32, period.

a4125514f5 There's a deadlock when ssleay_rand_bytes is called the first time, since
it wants to stir the pool using ssleay_rand_add.  This fix provides the
possibility to call ssleay_rand_add inside a locked state by simply telling
it not to do any locking through a static variable.  This isn't the most
elegant way one could do this, but it does retain thread safety during the
stirring process.

7ae634de49 Since ssleay_rand_initialize() unlocks then locks CRYPTO_LOCK_RAND,
it's a good thing if ssleay_rand_status() would do the corresponding
lock and unlock as everyone else...

eb952088f0 Precautions against using the PRNG uninitialized: RAND_bytes() now
returns int (1 = ok, 0 = not seeded). New function RAND_add() is the
same as RAND_seed() but takes an estimate of the entropy as an additional
argument.

62ac293801 Always hash the pid in the first iteration in ssleay_rand_bytes,
don't try to detect fork()s by looking at getpid().
The reason is that threads sharing the same memory can have different
PIDs; it's inefficient to run RAND_seed each time a different thread
calls RAND_bytes.

023c8d0b0a Use of DEVRANDOM must be #ifdef'ed (the #ifdef was commented out
between SSLeay 0.8.1b and 0.9.0b with no apparent reason).
If we *want* an error when DEVRANDOM is not defined (it always is with
the current e_os.h) we should use #error.

17f389bbbf Initial support for MacOS.
This will soon be complemented with MacOS specific source code files and
INSTALL.MacOS.

I (Andy) have decided to get rid of a number of #include <sys/types.h>.
I've verified it's ok (both by examining /usr/include/*.h and compiling)
on a number of Unix platforms. Unfortunately I don't have Windows box
to verify this on. I really appreciate if somebody could try to compile
it and contact me a.s.a.p. in case a problem occurs.

7e70181723 It was a very bad idea to use #include "../e_os.h" -- when this occurs
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.

d6847aed10 Add a kludge :-(
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.
