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.

The way we figured out what options are crypto algorithms and what are
something other was somewhat sketchy.  This change bases the
distinction on available sdirs instead.

        Ensure |BN_div| never gives negative zero in the no_branch code.

        Have |bn_correct_top| fix |bn->neg| if the input is zero so that we
        don't have negative zeros lying around.

        Thanks to Brian Smith for noticing.

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.

MIPS[32|64]R6 is binary and source incompatible with previous MIPS ISA
specifications. Fortunately it's still possible to resolve differences
in source code with standard pre-processor and switching to trap-free
version of addition and subtraction instructions.

Since vendor assembler can't assemble our modules with -KPIC flag,
it, assembly support, was not available as an option. But this
means lack of side-channel resistant code, which is incompatible
with security by todays standards.

So far, the test runner (test/run_tests.pl) could get a list of tests
to run, and if non were given, it assumes all available tests should
be performed.

However, that makes skipping just one or two tests a bit of a pain.
This change makes the possibilities more versatile, run_checker.pl
takes these arguments and will process them in the given order,
starting with an empty set of tests to perform:

    alltests            The current set becomes the whole set of
                        available tests.
    test_xxx            Adds 'test_xxx' to the current set.
    -test_xxx           Removes 'test_xxx' from the current set.  If
                        nothing has been added to the set before this
                        argument, the current set is first initialised
                        to the whole set of available tests, then
                        'test_xxx' is removed from the current set.
    list                Display all available tests, then stop.

If no arguments are given, 'alltests' is assumed.

These tests take a very long time on some platforms, and arent't
always strictly necessary.  This makes it possible to turn them
off.  The necessary binaries are still built, though, in case
someone still wants to do a manual run.

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
