to implement fchown(2) and fchmod(2) support for several file types
that previously lacked it. Add MAC entries for chown/chmod done on
posix shared memory and (old) in-kernel posix semaphores.

Replace all calls to minor() with dev2unit().2008-09-27T08:51:18ZEd Schoutened@FreeBSD.org2008-09-27T08:51:18Zurn:sha1:6bfa9a2d66dd0e00182017d6741d44e54d0b2cca
After I removed all the unit2minor()/minor2unit() calls from the kernel
yesterday, I realised calling minor() everywhere is quite confusing.
Character devices now only have the ability to store a unit number, not
a minor number. Remove the confusion by using dev2unit() everywhere.
This commit could also be considered as a bug fix. A lot of drivers call
minor(), while they should actually be calling dev2unit(). In -CURRENT
this isn't a problem, but it turns out we never had any problem reports
related to that issue in the past. I suspect not many people connect
more than 256 pieces of the same hardware.

Make ftruncate a 'struct file' operation rather than a vnode operation.2008-01-07T20:05:19ZJohn Baldwinjhb@FreeBSD.org2008-01-07T20:05:19Zurn:sha1:e46502943ac1471d7e3718557de87b17265985fe
This makes it possible to support ftruncate() on non-vnode file types in
the future.
- 'struct fileops' grows a 'fo_truncate' method to handle an ftruncate() on
a given file descriptor.
- ftruncate() moves to kern/sys_generic.c and now just fetches a file
object and invokes fo_truncate().
- The vnode-specific portions of ftruncate() move to vn_truncate() in
vfs_vnops.c which implements fo_truncate() for vnode file types.
- Non-vnode file types return EINVAL in their fo_truncate() method.

Remove explicit locking of struct file.2007-12-30T01:42:15ZJeff Robersonjeff@FreeBSD.org2007-12-30T01:42:15Zurn:sha1:397c19d1753d210247d77eb3ca33d1c7c1eb2fa9
- Introduce a finit() which is used to initailize the fields of struct file
in such a way that the ops vector is only valid after the data, type,
and flags are valid.
- Protect f_flag and f_count with atomic operations.
- Remove the global list of all files and associated accounting.
- Rewrite the unp garbage collection such that it no longer requires
the global list of all files and instead uses a list of all unp sockets.
- Mark sockets in the accept queue so we don't incorrectly gc them.

Remove the now-unused NET_{LOCK,UNLOCK,ASSERT}_GIANT() macros, which2007-08-06T14:26:03ZRobert Watsonrwatson@FreeBSD.org2007-08-06T14:26:03Zurn:sha1:0bf686c1257e2e7944a4cee9d9d628280facaa3d
previously conditionally acquired Giant based on debug.mpsafenet. As that
has now been removed, they are no longer required. Removing them
significantly simplifies error-handling in the socket layer, eliminated
quite a bit of unwinding of locking in error cases.
While here clean up the now unneeded opt_net.h, which previously was used
for the NET_WITH_GIANT kernel option. Clean up some related gotos for
consistency.
