* configure.ac (LIBUSB_LIBS,HAVE_LIBUSB): Check for Libusb.
(--enable-card-support): New.

* sign.c (do_sign) [ENABLE_CARD_SUPPORT]: Divert to card.
* cardglue.c, cardglue.h: New.
* Makefile.am (gpg_LDADD): Added.
(card_support_sources): New.

* memory.h (xmalloc): Define xmalloc macros in terms of m_alloc.
