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

ba3fe6d1ab Make -r a synonym for -R, similar to behavior on Linux while being backwards

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.

eedc99e7b5 cp -p could report success even if a file copy failed. This was due to
the cumulative exit status being overwritten when directory permissions
were being set.  This was particularly bad when called from mv(1) to
perform a cross-device move as the original files were deleted even if
the copy failed.

0d3bcc2e80 Make the threatened fts(3) ABI fix. FTSENT now avoids the use of the struct
hack, thereby allowing future extensions to the structure (e.g., for extended
attributes) without rebreaking the ABI.  FTSENT now contains a pointer to the
parent stream, which fts_compar() can then take advantage of, avoiding the
undefined behavior previously warned about.  As a consequence of this change,
the prototype of the comparison function passed to fts_open() has changed
to reflect the required amount of constness for its use.  All callers in the
tree are updated to use the correct prototype.

Comparison functions can now make use of the new parent pointer to access
the new stream-specific private data pointer, which is intended to assist
creation of reentrant library routines which use fts(3) internally.

a3ee32f3f7 Set WFORMAT=0, because our compiler currently complains about NULL
arg 2 to err() and friends, and warnings are promoted to errors.

This allows the following revisions to be reverted:

	rev 1.39	src/bin/cp/cp.c
	rev 1.26	src/bin/chmod/chmod.c
	rev 1.40	src/bin/rm/rm.c

The following revisions can already be reverted, because they were
already covered by WFORMAT=0:

	rev 1.8		src/bin/ls/lomac.c
	rev 1.63	src/bin/ls/ls.c
	rev 1.8		src/bin/ps/lomac.c
