- Add Mac OS X 10.9
- Add OpenBSD 5.4
- Change the master's URL.
Add some releases:
- Add NetBSD 5.1.4 and 5.2.2

Add 5.1.4, 5.2.2.  6.0.4 and 6.1.3.
Convert mtree spec path characters with sed(1) to avoid tool'ifying vis(1).
Testing "v_usecount == 1" for exclusive reference will not always
work -- remove and test only readonly.
msdosfs_reclaim(): add missing fstrans and protect change
of v_data with v_interlock as msdosfs_sync() now needs it.
vfs_vnode_iterator_next(): if a vnode is reclaiming (VI_XLOCK) skip
the filter.  Vget() will wait until the vnode disappeared.  No more
"dangling vnode" panics on unmount.
Change NFS from rbtree to vcache.
Import libc++ r209785. Fix a regression with std::bind exposed by recent
Clang improvements.
Drop undocumented and redundant 0 argument to .ent.
PR kern/48852 (which should have been bin/ in retrospect): apply patch
from Thomas Schmitt to fix rockridge encoding of device nodes.
Make it deal with /dev being the result of a "MAKDEV all" instead of
"MAKEDEV init" by mounting a ptyfs if needed.
The current vax /boot is super slow unziping kernels - and this is a CD, wich
has space enough, so unzip the kernel on it to speed up the boot process.
XXX The /boot bug should nevertheless be fixed.
Pre-populate /dev on the CD - with rockridge extensions we can do this and
it saves us one tmpfs (or mfs) instance, which helps quite a bit on low
memory machines.
len argument is of unsigned type (size_t) and thus cannot be negative;
remove corresponding statement in ERRORS.
Added Realtek devices.

Import LLVM 3.5svn r209886.
Import Clang 3.5svn r209886.
Update build system for LLVM/Clang snapshot r209886. This brings in the
merged AArch64 backend and the move of eARM to DWARF exception handling

Remove platform support list for libc unwinder, just keep comment about
ia64 state.
