f1172c58e5 Fix a bug where the callout might not be initialized before being used. 
Rev 1.9 introduced another path where machclk_freq would be initialized
before the rest of setup was done (i.e. initializing the callout).  Make
the one-time initialization a separate function and make init_machclk()
able to be called multiple times, any time.  We depend on tsc_freq first
being updated from the highest priority eventhandler, thus we run last
and call init_machclk() to set machclk_freq.  Also, don't initialize
static variables to 0.

b166b92692 Reimplement traverse() helper function: 
1. Pass locking flags to VFS_ROOT().
2. Check v_mountedhere while the vnode is locked.
3. Always return locked vnode on success.

Change 1 fixes problem reported by Stephen M. Rumble - after
zfs_vfsops.c,1.9 change, zfs_root() no longer locks the vnode
unconditionally and traverse() didn't pass right lock type to
VFS_ROOT(). The result was that kernel paniced when .zfs/ directory
was accessed via NFS.

5750956634 Adjust va_mask for setattr. FreeBSD doesn't have va_mask, so we initialize it 
based on individual fields beeing set. This doesn't work for setattr replay,
because va_type is set there, so we add AT_TYPE flag to va_mask, which won't
be accepted by zfs_setattr().

c28672efcc MFp4: Optimize mappedwrite() and mappedread() functions to write/read as much 
non-mapped data as possible at once and not page-by-page. Which this change we
combain I/Os, but also saves many VM_OBJECT_UNLOCK()/VM_OBJECT_LOCK()

performance increase.

171c4b21e2 - Always try to write one whole page at a time. 
- vm_page_undirty() is enough (instead of vm_page_set_validclean()), but it has
  to be called before we write the data in case someone makes page dirty after
  our write, but before our vm_page_undirty() call.
- Always dmu_write, not matter if uiomove() succeeded, because it could
  partially be ok and we would lose some changes.
