f815125fbc Implement an "-x" option to cp(1), for compatibility with Linux and
feature parity with du(1) and similar:  When set, cp(1) will not traverse
mount points.

2689ba2720 Add NFSv4 ACL support to cp(1) and fix a few memory leaks.
Note that this changes error reporting behaviour somewhat - before,
no error was reported if ACL couldn't be copied because the target
filesystem doesn't support ACLs.  Now, it will be reported - of course,
only if there actually is an ACL to copy.

e9cbc9a770 Teach cat(1) and cp(1) to use a larger buffer if enough memory is present
in the system. A simple heuristics is used to detect what is "enough"
memory: if number of physmem pages is greater than 32k (equalling 128 MB
on machines with 4 kB pages).

Typical immediate result of these changes is reduction in context switches
and the goal is to increase efficiency by using large buffers:
before: /usr/bin/time -hlp cat file1 > file2
...
       163  voluntary context switches
     11194  involuntary context switches
after: /usr/bin/time -hlp ./cat file1 > file2
...
       417  voluntary context switches
       272  involuntary context switches

9b4261c9b4 Attempt to complete the userspace integration of POSIX.1e extended ACLs.
This includes adding support for ACLs into cp(1) and mv(1) userspace
utilities.

For mv(1), if _PC_ACL_EXTENDED is in effect for the source AND destination
operands, the destination file's ACLs shall reflect the source.

For cp(1), if _PC_ACL_EXTENDED is in effect for both source and destination
operands, and -p has been specified, the ACLs from the source shall be
preserved on the destination.

e1d071dbfd Removed the broken code which claimed to lose the set[ug]id bits in
the !(pflag && setfile()) case for regular files unless the copy is
owned by the same user and group.  These bits have already been lost
(or never gained) in the correct way.  The code didn't actually lose
the bits; it depended on them being lost already (apparently in all
cases) and attempted to gain them as necessary, but it often gained
them (and sometimes collateral bits) when wrong:
- pflag && setfile() == 0 case (i.e., for a successful cp -p):
  setfile() copies all the attributes as correctly as possible (as
  specified by POSIX), and we sometimes messed up the up the mode by
  setting it again.  Also, if the file is immutable, then setting the
  mode again gave spurious errors (PR 20646).
- !pflag case.  If the target is created, POSIX requires it to not
  have the set[ug]id bits, but we sometimes copied them from the source.
  If the target already exists, POSIX requires its mode to be unchanged,
  but we sometimes copied the whole mode from the source.

40fc4ee2de Don't use mmap() for non-regular files, since st_size is only meaningful
for regular files.  This fixes recent breakage of cp'ing from /dev/zero.
/dev/zero doesn't support mmap(), but the device driver mmap routines are
not called for mapping 0 bytes, so the error was not detected.  mmap()
can't even be used for cp'ing special files that support mmap(), since
there is general way to determine the file size.

4faaa03777 Don't attempt to change owner/mode/flags that don't need to changed.
This should calm down attempts to `cp -p' to a nfs mount or some other
filesystem that doesn't accept flags or all combinations of flags.
It will warn if it fails to change flags though.

8abdc2eb40 Sweep through the tree fixing mmap() usage:
- Use MAP_FAILED instead of the constant -1 to indicate
    failure (required by POSIX).
  - Removed flag arguments of '0' (required by POSIX).
  - Fixed code which expected an error return of 0.
  - Fixed code which thought any address with the high bit set
    was an error.
  - Check for failure where no checks were present.
