update tcplay to 2.0
cryptdisks - update to new tcplay API
cryptdisks safe_mem - use weak symbols

 * Use weak symbols so that the ones in libtcplay.a can override the
   symbols in the local safe_mem.

 * I'm not sure why this ever worked before, but it definitely doesn't
   work anymore.
tcplay - fix compile error on i386
usb4bsd: Port ufm.

Mainly s/callout_init/callout_init_mp/ and using pci_enable_busmaster()
