openssl/util/wrap.pl
Richard Levitte 285e2991af TEST: add util/wrap.pl and use it
util/wrap.pl is a script that defines the environment variables
OPENSSL_ENGINES and OPENSSL_MODULES, then calls the command line
that's given as its arguments.

On a POSIX platform, the command line call is done via
util/shlib_wrap.sh to ensure that the shared library paths are
correct.  For other platforms, util/wrap.pl currently assumes that
similar things are already in place through other means.
