Certain functions are automatically called during auto-deinit in order
to deallocate resources. However, if we have never entered a function which
marks lib crypto as inited then they never get called. This can happen if
the user only ever makes use of a small sub-set of functions that don't hit
the auto-init code.

This commit ensures all such resources deallocated by these functions also
init libcrypto when they are initially allocated.

The background story is that util/shlib_wrap.sh was setting LD_PRELOAD
or similar platform dependent variables, just in case the shared
libraries were built with -rpath.  Unfortunately, this doesn't work
too well with asan, msan or ubsan.

So, the solution is to forbid the combination of shared libraries,
-rpath and any of the sanity analyzers we can configure.

This changes util/shlib_wrap.sh so it only contains the code that sets
LD_PRELOAD when -rpath has been used when configuring.

Some hardware devices don't provide the public EC_POINT data. The only
way for X509_check_private_key() to validate that the key matches a
given certificate is to actually perform a sign operation and then
verify it using the public key in the certificate.

Maybe that can come later, as discussed in issue 1532. But for now let's
at least make it fail gracefully and not crash.

In the case of using an independent makedepend, we had split that into
two separate recipes, one depending on the other.  However, there are
cases where the makedepend recipe was always trying, but doesn't
update the time stamp of the .d file because there are no actual
changes, and thereby causing constant updates of the object files.

This change makes one recipe that takes care of both makedepend och
cc, thereby avoiding these extra updates.

Build file templates would be looked up like this if the user gave us
an additional directory to look for configuration files and build file
templates:

    $OPENSSL_LOCAL_CONFIG_DIR/$OSTYPE-Makefile.tmpl
    $SOURCEDIR/Configurations/$OSTYPE-Makefile.tmpl
    $OPENSSL_LOCAL_CONFIG_DIR/Makefile.tmpl
    $SOURCEDIR/Configurations/Makefile.tmpl

So for example, if the user created his own Makefile.tmpl and tried to
use it with a unixly config, it would never be user because we have a
unix-Makefile.tmpl in our Configurations directory.  This is clearly
wrong, and this change makes it look in this order instead:

    $OPENSSL_LOCAL_CONFIG_DIR/$OSTYPE-Makefile.tmpl
    $OPENSSL_LOCAL_CONFIG_DIR/Makefile.tmpl
    $SOURCEDIR/Configurations/$OSTYPE-Makefile.tmpl
