_NETBSD_SOURCE as this makes cross building from older/newer versions of
NetBSD harder, not easier (and also makes the resulting tools 'different')
Wrap all required code with the inclusion of nbtool_config.h, attempt to
only use POSIX code in all places (or when reasonable test w. configure and
provide definitions: ala u_int, etc).
Reviewed by lukem. Tested on FreeBSD 4.9, Redhat Linux ES3, NetBSD 1.6.2 x86
NetBSD current (x86 and amd64) and Solaris 9.

makeoptions selector FOO+=bar
"selector" may be anything used as a key in the selecttab, i.e. an option,
a "device" name, an "attach" name, a file system, etc.
Semantics: FOO+=bar when the selector is set. For example, if you have:
makeoptions pickle CPPFLAGS+=-I${S}/picklesrc
then "options PICKLE" will cause "CPPFLAGS+=-I${S}/picklesrc" to be
added to the Makefile.
Suggested by Matt Thomas.
makeoptions FOO+=bar
Multiple appending makeoptions are allowed. These are then emitted at
the %MAKEOPTIONSAPPEND token in the Makefile template.
Syntax suggested by Matt Thomas.
- Not enabled by default. Needs kernel option FFS_SNAPSHOT.
- Change parameters of ffs_blkfree.
- Let the copy-on-write functions return an error so spec_strategy
may fail if the copy-on-write fails.
- Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock.
- Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer.
- Add a function ffs_checkfreefile needed for snapshot creation.
- Add special handling of snapshot files:
Snapshots may not be opened for writing and the attributes are read-only.
Use the mtime as the time this snapshot was taken.
Deny mtime updates for snapshot files.
- Add function transferlockers to transfer any waiting processes from
one lock to another.
- Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through
a vnode.
- Add snapshot support to ls, fsck_ffs and dump.
