This change will cause builds (by default) to not use different STACK
structures and functions for each stack type. The previous behaviour can be enabled by configuring with the "-DDEBUG_SAFESTACK" option. This will also cause "make update" (mkdef.pl in particular) to update the libeay.num and ssleay.num symbol tables with the number of extra functions DEBUG_SAFESTACK creates. The way this change works is to accompany each DECLARE_STACK_OF() macro with a set of "#define"d versions of the sk_##type##_*** functions that ensures all the existing "type-safe" stack calls are precompiled into the underlying stack calls. The presence or abscence of the DEBUG_SAFESTACK symbol controls whether this block of "#define"s or the DECLARE_STACK_OF() macro is taking effect. The block of "#define"s is in turn generated and maintained by a perl script (util/mkstack.pl) that encompasses the block with delimiting C comments. This works in a similar way to the auto-generated error codes and, like the other such maintenance utilities, is invoked by the "make update" target. A long (but mundane) commit will follow this with the results of "make update" - this will include all the "#define" blocks for each DECLARE_STACK_OF() statement, along with stripped down libeay.num and ssleay.num files.
