fd10995478 Add fdclose(3) function.
This function is equivalent to fclose(3) function except that it
does not close the underlying file descriptor.
fdclose(3) is step forward to make FILE structure private.

4232f82668 Enforce overwritting SHLIBDIR
Since METAMODE has been added, sys.mk loads bsd.mkopt.mk which ends load loading
bsd.own.mk which then defines SHLIBDIR before all the Makefile.inc everywhere.

This makes /lib being populated again.

b7c4ed65cc NetBSD commit log:
Use a constant array for the MIB. Newer LLVM decided that mib[] warranted
  stack protections, with the obvious crash after the setup was done.
  As a positive side effect, code size shrinks a bit.

I'm not sure why this hasn't bitten us yes, but it is certainly possible and
there are no real drawbacks to this change anyway.

ccfb965433 Add META_MODE support.

WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

24e8388b29 Use a register to set the cpsr bits. The ip register is safe to be changed
within all of these functions, and is only stored in some to correctly pad
the stack.

This will be needed to build as Thumb-2 as, unlike with ARM instructions,
the msr instruction only takes a register as the input.

An empty big string (arg "l") is handled by the existing

2b6a6357f2 Teach bits of libc about Thumb. This adds the if-then instructions needed
to handle the ARM conditional execution.

While here fix a bug found by this in the hard-float code, cc is the
opposite of cs. The former is used for 'less than' in floating-point code
and is executed when the C (carry) bit is clear, the latter is used when
greater than, equal, or unordered, and is executed when the C bit is set.

recv() and send()'s calls to recvfrom() and sendto() are much like
waitpid()'s call to wait4(), and likewise need not allow PLT interposing on

as seek to teh last location saved will still work. This is needed for Samba
to be able to correctly handle delete requests from windows. This does not
completely fix seekdir when deletes are present but fixes the worst of the
problems. The real solution must involve some changes to the API for eh VFS

196cd80898 Various updates to the ftruncate(2) documentation:
- Note that ftruncate(2) can operate on shared memory objects and cross
  reference shm_open(2).
- Note that ftruncate(2) does not change the file position pointer (aka
  seek pointer) of the file descriptor.
- ftruncate(2) will fail with EINVAL for all sorts of other fd types than
  just sockets, so instead note that it fails for all but regular files and
  shared memory objects.
- Note that ftruncate(2) also appeared in 4.2BSD along with truncate(2).
  (Or at least the manpage for both appeared in 4.2, I did not check the
  kernel code itself to see if either predated 4.2.)
