Fix a partial construction problem that can cause race conditions
...
between creation of a file descriptor and close(2) when using kernel
assisted threads. What we do is stick descriptors in the table, but
mark them as "larval". This causes essentially everything to treat
it as a non-existent descriptor, except for fdalloc(), which sees a
filled slot so that it won't (incorrectly) allocate it again. When
a descriptor is fully constructed, the code that has constructed it
marks it as "mature" (which actually clears the "larval" flag), and
things continue to work as normal.
While here, gather all the code that gets a descriptor from the table
into a fd_getfile() function, and call it, rather than having the
same (sometimes incorrect) code copied all over the place.

Read the PCI memory space base and the PCI DMA window base from the

V3 PBC, and use them in the bus mem tag and the bus dma tag on the

Since physical memory below 0x2000 isn't mapped anywhere
...
for now, return EFAULT when /dev/mem tries to read it.
Other physical memory not managed by the pmap system is
mapped at the same virtual addresses. Now that we
understand how VME PTEs are constructed, give mmapping
a VME bus a better chance of working..
