e4573a9a7b Return "failure" as we do for 'cp -i' and a "n" answer. 
Otherwise with '-v' we print out the file name as if it was copied:
   /tmp/2gb-card/M0132.CTG not overwritten
   /mnt/DCIM/CANONMSC/M0132.CTG -> /tmp/2gb-card/M0132.CTG

9fa5f90fbf Don't try to copy a socket after "xxx is a socket (not copied)." message. 
Previously, it would either try to copy it anyway and fail (without -R),
or create fifo instead of the socket (with -R).

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.
