Use _BSD_OFF_T_ instead of off_t so that we're still self-sufficent.
Copied the ftruncate/lseek()/mmap()/truncate() redeclaration hacks
from <sys/types.h> so that things depending on them don't break.
cause noise.
Duplicated the lseek() redeclaration hack for all functions involving
off_t's (ftruncate(), mmap() and truncate()) to help broken programs
work.
<machine/types.h> gets redefined in the non-GNU and non-ANSI cases.
Since this hasn't caused problems, there must be no one actually
benefitting from the obfuscations supported by <sys/cdefs.h>.
`make CC="cc -traditional"' in /usr/src/bin shows the same. Almost
everything is broken in essentially the same way - `const' is used
in strings before <sys/cdefs.h> is included, so `const' is not
#defined away until after it is used.
Fixed some style bugs.
TTY_NETWORK (network), TTY_DIALUP (dialup), which determine a basic
connection type. TTY_DIALUP in particular will replace the old out of
date heuristic "tty[dD]*" in login.c (and better than the current
hard-coded method).
`void __set_ospeed(long);' in the appropriate header.
The implementation still uses speed_t instead of long. This
will break properly when speed_t is fixed (speed_t shall be
unsigned ...).
dependent utilities to /bootstrap inside the chroot tree, so the
hosting and targeted environment are not required the same. By now,
mount/umount (due to the Lite2 changes) and cpio (due to lchown) make
it there. This should allow building a 3.0-current release from
inside a 2.2 vintage system, and visa verse.
Isn't lchown also a reason for a shared lib version number bump?

dolock is not set (that is, targetvp == overlaying vnode object).
Current code use FIXUP macro to do this, and never unlocks overlaying
vnode object in union_fsync. So, the vnode object will be locked
twice and never unlocked.

relookup() in union_relookup() is succeeded. However, if relookup()
returns non-zero value, that is relookup fails, VOP_MKDIR is never
called (c.f. union_mkshadow). Thus, pathname buffer is never FREEed.

Implement rfork(!RFPROC !RFMEM), which allows a thread to divorce its memory
from the other threads of a group.
Implement rfork(!RFPROC RFCFDG), which closes all file descriptors, eliminating
possible existing shares with other threads/processes.
Implement rfork(!RFPROC RFFDG), which divorces the file descriptors for a
thread from the rest of the group.
Fix the case where a thread does an exec. It is almost nonsense for a thread
to modify the other threads address space by an exec, so we
now automatically divorce the address space before modifying it.
