  (and that malloc can be called with an int argument).
- Use proper prototypes (with argument list) for various function pointers,
  avoid casts  (however there are still many such cases left in these files).
- Avoid collissions in app_info_cmp if sizeof int != sizeof long.
- Use CRYPTO_LOCK_MALLOC in mem_dbg.c.

 - Made CRYPTO_MDEBUG even less used in crypto.h, giving
   MemCheck_start() and MemCheck_stop() only one possible definition.
 - Made the values of the debug function pointers in mem.c dependent
   on the existence of the CRYPTO_MDEBUG macro, and made the rest of
   the code understand the NULL case.

That's it.  With this code, the old behvior of the debug functionality
is restored, but you can still opt to have it on, even when the
library wasn't compiled with a defined CRYPTO_MDEBUG.

 - Moved the handling of compile-time defaults from crypto.h to
   mem_dbg.c, since it doesn't make sense for the library users to try
   to affect this without recompiling libcrypto.
 - Made sure V_CRYPTO_MDEBUG_TIME and V_CRYPTO_MDEBUG_THREAD had clear
   and constant definitions.
 - Aesthetic correction.

from MemCheck_start() to CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON)
because that is what applications should use
(MemCheck_start/stop never really worked for applications
unless CRYPTO_MDEBUG was defined both when compiling the library
and when compiling the application, so probably we should
get rid of it).

With this change, the following is provided and present at all times
(meaning CRYPTO_MDEBUG is no longer required to get this functionality):

  - hooks to provide your own allocation and deallocation routines.
    They have to have the same interface as malloc(), realloc() and
    free().  They are registered by calling CRYPTO_set_mem_functions()
    with the function pointers.

  - hooks to provide your own memory debugging routines.  The have to
    have the same interface as as the CRYPTO_dbg_*() routines.  They
    are registered by calling CRYPTO_set_mem_debug_functions() with
    the function pointers.

I moved everything that was already built into OpenSSL and did memory
debugging to a separate file (mem_dbg.c), to make it clear what is
what.

With this, the relevance of the CRYPTO_MDEBUG has changed.  The only
thing in crypto/crypto.h that it affects is the definition of the
MemCheck_start and MemCheck_stop macros.
