replace our obsolete smartcard code with PKCS#11.

	ftp://ftp.rsasecurity.com/pub/pkcs/pkcs-11/v2-20/pkcs-11v2-20.pdf
ssh(1) and ssh-keygen(1) use dlopen(3) directly to talk to a PKCS#11
provider (shared library) while ssh-agent(1) delegates PKCS#11 to
a forked a ssh-pkcs11-helper process.
PKCS#11 is currently a compile time option.
feedback and ok djm@; inspired by patches from Alon Bar-Lev

+/* This file is a modified implementation of the PKCS #11 standard by
+   RSA Security Inc.  It is mostly a drop-in replacement, with the
+   following change:
+
+   This header file does not require any macro definitions by the user
+   (like CK_DEFINE_FUNCTION etc).  In fact, it defines those macros
+   for you (if useful, some are missing, let me know if you need
+   more).
+
+   There is an additional API available that does comply better to the
+   GNU coding standard.  It can be switched on by defining
+   CRYPTOKI_GNU before including this header file.  For this, the
+   following changes are made to the specification:
+
+   All structure types are changed to a "struct ck_foo" where CK_FOO
+   is the type name in PKCS #11.
+
+   All non-structure types are changed to ck_foo_t where CK_FOO is the
+   lowercase version of the type name in PKCS #11.  The basic types
+   (CK_ULONG et al.) are removed without substitute.
+
+   All members of structures are modified in the following way: Type
+   indication prefixes are removed, and underscore characters are
+   inserted before words.  Then the result is lowercased.
+
+   Note that function names are still in the original case, as they
+   need for ABI compatibility.
+
+   CK_FALSE, CK_TRUE and NULL_PTR are removed without substitute.  Use
+   <stdbool.h>.
+
+   If CRYPTOKI_COMPAT is defined before including this header file,
+   then none of the API changes above take place, and the API is the
+   one defined by the PKCS #11 standard.  */
