build them there.

A command procedure to build the external engines is on it's way.

into libcrypto, we need the "algorithm" STATIC_ENGINE.

RSAref data, pretend we don't care for OpenSSL's MD2 and MD5 structures or
implementation.
Remove all kinds of silly warning

apps.h.  For those, it's better to include apps.h after the system
headers where those symbols may be defined, since there's otherwise a
chance that the C compiler will barf when it sees something that looks
like this after expansion:

int VMS_strcasecmp((str1),(str2))(const char *, const char *);

first.

of libcrypto, then it is possible that when they are loaded they will share
the same static data as the loading application/library. This means it will
be too late to set memory/ERR/ex_data/[etc] callbacks, but entirely
unnecessary to try. This change puts a static variable in the core ENGINE
code (contained in libcrypto) and a function returning a pointer to it. If
the loaded ENGINE's return value from this function matches the loading
application/library's return value - they share static data. If they don't
match, the loaded ENGINE has its own copy of libcrypto's static data and so
the callbacks need to be set.

Also, although 0.9.7 hasn't been released yet, it's clear this will
introduce a binary incompatibility between dynamic ENGINEs built for 0.9.7
and 0.9.8 (though others probably exist already from EC_*** hooks and
what-not) - so the version control values are correspondingly bumped.

idea why, but that was definitely wrong...

write external engines (and thus should require only installed openssl
headers and libs to compile without warnings). So this gets rid of recently
introduced compilation warnings (no longer including internal headers) by
including string.h directly.

normal 'structural' case (ENGINE_init() satisfies this in the less normal
'functional' case). This change provides such a function.

- Correct some "read" locks that should actually be "write" locks.

- make update.

Make sure test doesn't barf because of missing spaces before the

Add -lc to the list of libraries we depend upon.  Not always
necessary, but never hurts.
