Split the work for sys_stat, sys_lstat, sys_fstat and sys_fhstat out into
...
separate functions that don't do the copyout.
This allows all the compat_xxx versions to convert the 'struct stat' to
the correct format without using the 'stackgap'.
The stackgap isn't at all LWP friendly, and needs to be removed from
any compat functions that might involve threads (inc. clone()).
The code is still binary compatible with existing LKMs.

Make the attach functions for real and pseudo devices share as much code
...
as possible. For that, split out a function which does the allocation
of a softc (without linking it into global structures) and a function
which inserts the device into the global alldevs lists and the per-driver
cd_devs.
There is a little semantic change involved: the pseudo-device code didn't
interpret FSTATE_STAR as such, for no good reason. This looks harmless;
I'll modify driver frontends as I find ways to test.
Get config_makeroom() out of the public namespace - that's clearly an
internal of autoconf which drivers can't be allowed to deal with.
