- 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.

Remove duplicated copies of various NetBSD compatibility shims used by
makefs and use libnetbsd, contrib/mtree, and contrib/mknod instead.

Add support for using mtree(5) manifest files to define the image
to be created. The support is based on mtree version 2.0, as used
in libarchive, but adds new features on top of it.

The current implementation is fully functional, but is envisioned
to grow at least the following additional features over time:
o Add support for the /include special command so that manifest
files can be constructed using includable fragments.
o Add support specifying a search path to locate content files.
o Content file filters: commands that provide file contents on
stdout.

The manifest file eliminates the need to first construct a tree
as root in order to create an image and allows images (releases)
to be created directly from object trees and/or source trees.

Sync with the latest version from NetBSD. It notably addds ISO9660 support.

fix pathnames to work w/ buildworld

import netbsd makefs tool

add properties and FreeBSD id's

enable support for st_flags and st_gen

Apply the big hammer:
o remove all of compat except for pwcache and strstuftoll; these might
end up in libutil or similar so keep them in the subdir
o mv getid.c up to the top level; this looks like something that'll be
makefs-specific
o eliminate private versions of .h files in sys; use system files instead
o eliminate private ffs_tables.c; use the system version directly (might
want to adopt const'ification at some point but that's the only diff I
can see)
o mv remaining code from sys to ffs and strip out unused bits; this now
becomes part of makefs
o add compat defs and shims to makefs.h
o strip all vestiges of nbtool_config.h, compat_defs.h, etc.
o fixup includes after file shuffling
o rename system #defines that do implicit byte swapping to have an _swap
suffix; e.g. DIRSIZ -> DIRSIZ_SWAP, cg_inosused -> cg_inosused_swap; if
we ever add endian-agnostic support to the kernel these can go back to
their original names
o strip some netbsd'isms that aren't worth shim'ing (e.g. _DIAGASSERT)

Code compiles w/o complaints but is untested.

First step toward proper mtree integration:
o use mtree code directly from ../mtree; s/spec(fp)/mtree_readspec(fp)/
(assume this will eventually go in usr.sbin)
o nuke st_rdev use; there's no reason to create filesystems with device nodes
o shim missing compat bits for inotype and nodetoino
o remove now unneeded compat/mtree bits, pack_dev.?, and stat_flags.?
o temporarily move getid.c code up to compat to keep this building

split stanzas in preparation for better integration

Remove the dump_node and vispath routines from compat/mtree/spec.c.
They aren't needed, and were the only users of the compat/vis.[ch]
files. As such, remove them from the Makefile.
