John Baldwin 06e8730c59 Add locking to the twe(4) driver and make it MPSAFE: ... - Add per-controller configuration (sx) and I/O (mutex) locks. The configuration lock protects the relationship of volumes and drives while the I/O lock protects access to the controller's registers and the main I/O path. - Remove some checks for M_WAITOK malloc()'s failing. - Remove the explicit bus space tag/handle from the softc and use bus_*() rather than bus_space_*(). - Reuse the existing new-bus sysctl context instead of creating a new one. - Remove compat shims for FreeBSD 4.x. - Use pci_enable_busmaster() rather than doing it by hand, and rely on bus_alloc_resource() to enable PCI I/O decoding.
