refactor pk11util, splitting large single files down to a managable size.
bug 246130. The new factor is:

pk11akey.c - asymetric keys constructed from pk11cert.c and pk11skey.c
pk11auth.c - authentication/password management factored from pk11slot.c
pk11cert.c - cert code with private key, crls and trust factored out.
pk11ctx.c -- pkcs11 context code, factored out of pk11skey.c
new pk11func.h -- for backward compatibility.
pk11mech.c - mechanism mapping code, factored mostly from pk11slot.c
pk11nobj.c - netscape objects (crls and trust), factored mostly from pk11cert.c
pk11obj.c - generic object support, factored from pk11skey.c pk11slot.c and
pk11cert.c
pk11priv.h -- private functions factored from pk11func.h
pk11pub.h -- public functions factored from pk11func.h
pk11skey.c - now only symetric key ops; private, public key ops, generic ops
and crypto contexs have been factored out.
pk11slot.c - still slot operations. Authentication, generic object ops,
mechanism mapping has been factored out.

This patch should only have refactoring, no new functions or other changes.
