Replace 4 identical copies of *_setcurrdev with gen_setcurrdev to avoid
having to create a 5th copy. uboot_setcurrdev is actually different and
needs to remain separate (even though it's quite similar).

These are declared as extern in a number of files (some with the wrong
return type). Centralize this in modinfo.h and remove a few extra stray
declarations as well that are no longer used. No functional change.
Note: I've not tried to cope with the bi_load() functions which are the
same logical thing. These will be handled separately.

Both ofw_disk and ofw_net use the same parsedev routine, except for the
string passed in to match the ofw device node's type. Create a routine
to do that and connect these two users up to that.

We need to match devices in a slightly special way: We have to look up
the path and see if the device is a 'network' device in order to use it.

ofw_path_to_handle converts a path string to a phandle_t. It searches
down the path for the first device whose type matches the passed-in
string.

The rest of the code in the tree assumes that a DEVT_DISK uses a
disk_devdesc to represent the device. However ofw_disk diesn't, so we
can't use disk_fmtdev, nor disk_parsedev. ofw needs to have a
dv_match-like routine to use devpasrse, though, since we have two
drivers (net and block) that claim the same sort of devices (eg
/path/to/ofw-dev) based on the device-type property. In the interim, we
can't use devmatch and ofw_disk's and the default net driver's parsing
is offloaded ofw_parsedev.

The vectx API, computes the hash for verifying a file as it is read.
This avoids the overhead of reading files twice - once to verify, then
again to load.
For doing an install via loader, avoiding the need to rewind
large files is critical.
This API is only used for modules, kernel and mdimage as these are the
biggest files read by the loader.
The reduction in boot time depends on how expensive the I/O is
on any given platform. On a fast VM we see 6% improvement.
For install via loader the first file to be verified is likely to be the
kernel, so some of the prep work (finding manifest etc) done by
verify_file() needs to be factored so it can be reused for
vectx_open().
For missing or unrecognized fingerprint entries, we fail
in vectx_open() unless verifying is disabled.
Otherwise fingerprint check happens in vectx_close() and
since this API is only used for files which must be verified
(VE_MUST) we panic if we get an incorrect hash.

Since rS330365, there has been no particular reason for libofw to be in a
subdirectory of ofw. Move libofw up a level to make it fit in better with
the other top level libraries.
Also add a LIBOFWSRC to stand/defs.mk to match what all the other
libraries are doing.
