Add new function BN_bn2binpad() which checks the length of the output
buffer and pads the result with zeroes if necessary.

New functions BN_bn2lebinpad() and BN_lebin2bn() which use little endian
format.

Nothing else will run the unified scheme for now.

Now that we have the foundation for the "unified" build scheme in
place, we add build.info files.  They have been generated from the
Makefiles in the same directories.  Things that are platform specific
will appear in later commits.

The "unified" build scheme revolves around small information files,
build.info, which each describe their own bit of everything that needs
to be built, using a mini-language described in Configurations/README.

The information in build.info file contain references to source files
and final result.  Object files are not mentioned at all, they are
simply from source files.  Because of this, all the *_obj items in
Configurations/*.conf are renamed to *_asm_src and the files listed
in the values are change from object files to their corresponding
source files.  For the sake of the other build schemes, Configure
generates corresponding *_obj entries in %target.

Furthermore, the "unified" build scheme supports having a build
directory tree separate from the source directry tree.

All paths in a build.info file is assumed to be relative to its
location, either within the source tree or within the build tree.

When auxiliary data contains only reject entries, continue to trust
self-signed objects just as when no auxiliary data is present.

This makes it possible to reject specific uses without changing
what's accepted (and thus overring the underlying EKU).

Added new supported certs and doubled test count from 38 to 76.

This includes basic constraints, key usages, issuer EKUs and auxiliary

Not all architectures have a time_t defined the same way.  To make
sure we get the same result, we need to cast &checkoffset to (intmax_t *)
and make sure that intmax_t is defined somehow.

To make really sure we don't pass a variable with the wrong size down
to opt_imax(), we use a temporary intmax_t.
