- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Until now, smbfs_fullpath() computed the full path starting from the
vnode and following back the chain of n_parent pointers up to the root,
without acquiring the locks of the n_parent vnodes analyzed during the
computation. This is immediately wrong because if the vnode lock is not
held there's no guarantee on the validity of the vnode pointer or the data.
In order to fix, store the whole path in the smbnode structure so that
smbfs_fullpath() can use this information.

Fix panic due to page faults while in kernel mode, under conditions of
VM pressure. The reason is that in some codepaths pointers to stack
variables were passed from one thread to another.

Ditch crummy fattime <--> timespec conversion functions

Since DELAY() was moved, most <machine/clock.h> #includes have been
unnecessary.

Normalize a significant number of kernel malloc type names:

- Prefer '_' to ' ', as it results in more easily parsed results in
memory monitoring tools such as vmstat.

- Remove punctuation that is incompatible with using memory type names
as file names, such as '/' characters.

- Disambiguate some collisions by adding subsystem prefixes to some
memory types.

- Generally prefer lower case to upper case.

- If the same type is defined in multiple architecture directories,
attempt to use the same name in additional cases.

Not all instances were caught in this change, so more work is required to
finish this conversion. Similar changes are required for UMA zone names.

/* -> /*- for copyright notices, minor format tweaks as necessary

Don't follow smbnode n_parent pointer when NREFPARENT flag is not set
in smb_fphelp(): the parent vnode may have already been recycled
since we don't hold a reference to it. Fixes a panic when rebooting
with mdconfig -t vnode devices referring to vnodes on a smbfs mount.

Split the global timezone structure into two integer fields to
prevent the compiler from optimizing assignments into byte-copy
operations which might make access to the individual fields non-atomic.

Use the individual fields throughout, and don't bother locking them with
Giant: it is no longer needed.

Store a reference to the parent directory's vnode in struct smbnode,
not to the parent's smbnode, which may be freed during the lifetime
of the child if the mount is forcibly unmounted. umount -f should now
work properly (ie. not panic) on smbfs mounts.

Import kernel part of SMB/CIFS requester.
