build OpenSSL without symlink trees:

* manpage related things moved to src/libssl/man/Makefile
* there are now 3 obj directories src/libssl/{crypto,ssl,man}/ instead
of one single src/libssl/obj
* instead of running Configure (with generates lots of symlinks, and
opensslconf.h) this patch stores pre-computed opensslconf.h files
in src/libssl/crypto/arch
* requires a make includes before the library can be built
* libssl and libcrypto can be build separately
(e.g. cd src/libssl/ssl && make obj && make)
* make depend is now supported
* no more symlink trees
