shl_load() also needs to load along a path given through an
environment variable, SHLIB_PATH. This change makes that possible.

Add configuration option to build on Linux on both big-endian and
little-endian MIPS.
Submitted by Ralf Baechle <ralf@uni-koblenz.de>

Merge the engine branch into the main trunk. All conflicts resolved.
At the same time, add VMS support for Rijndael.

FreeBSD-elf can do threads. However, there seems to be confusion if
you should defined _THREAD_SAFE (I found that in an include file, and
that's what everybody tells me) or _THREADSAFE (that's what the gcc
manual says in the FreeBSD-specific section), so I defined both, just
to be safe.

Add what's needed to get shared libraries on HP-UX.

N.B.: This has not been tested at all, that's my next step.

Even when you don't want to create shared libraries, it's a good idea
to have the full extension information, so residual shared libraries
can be removed so the applications and test programs

against them by mistake...

Rework the system to generate shared libraries:

- Make note of the expected extension for the shared libraries and
if there is a need for symbolic links from for example libcrypto.

Rework the system to generate shared libraries:

- Make note of the expected extension for the shared libraries and
if there is a need for symbolic links from for example libcrypto.so.0
to libcrypto.so.0.9.7. There is extended info in Configure for
that.

- Make as few rebuilds of the shared libraries as possible.

- Still avoid linking the OpenSSL programs with the shared libraries.

- When installing, install the shared libraries separately from the
static ones.

Make sure that shareable libraries are turned off if we don't know how
to make them...

Linux on Alpha with gcc knows about shared libraries.

Kris Kennaway <kris@FreeBSD.org> tells us that FreeBSD/Alpha shouldn't
use an optimization higher than -O.

Portability patch for HP MPE/iX. Submitted by Mark Bixby <mark_bixby@hp.com>

HP-UX 64-bit has dlfcn, so let's use that instead of the old dl.

Typo in the added hpux targets. -ldl should be -ldld.

A patch from HP for better performance.

Add a configuration for Sony News 4.
Submitted by NAKAJI Hiroyuki <nakaji@tutrp.tut.ac.jp>

Make sure that Configure will defined DSO_WIN32 for the Win32 targets. I feel a bit unsure if this should really be done for Mingw32 and CygWin32

debug-linux-elf and debug-linux-elf-efence need to be linked with
libdl just as linux-elf...

Changes for QNX: there is no thread support, and the previous
configuration only worked with no-asm.

*BIG* verify code reorganisation.

The old code was painfully primitive and couldn't handle
distinct certificates using the same subject name.

The new code performs several tests

*BIG* verify code reorganisation.

The old code was painfully primitive and couldn't handle
distinct certificates using the same subject name.

The new code performs several tests on a candidate issuer
certificate based on certificate extensions.

It also adds several callbacks to X509_VERIFY_CTX so its
behaviour can be customised.

Unfortunately some hackery was needed to persuade X509_STORE
to tolerate this. This should go away when X509_STORE is
replaced, sometime...

This must have broken something though :-(

Avoid abort() throughout the library, except when preprocessor
symbols for debugging are defined.

QNX 4 support.

Allow reconfiguration. This can be useful if some source update
requires that you configure again, but you don't want to reenter all
those configuration arguments again.

IBMcxx complains that maxmem is as low as 2048 for certain modules
(like all the digests). Setting maxmem to 16K seems to give the
compiler enough space to do all the optimization it wants.
