ccfb965433 Add META_MODE support.
Off by default, build behaves normally.
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.

7ea2450f42 Implement '-s' to copy as symlink, similar to the current -l link(2) handling.
This is also implemented in at least GNU coreutils cp.

While here also improve the '-l' handling to not open(2) the source file as
it does not actually need the descriptor.

c633f8dc04 cp: Remove fts sorting.
In an attempt to improve performance, cp reordered directories first
(although the comment says directories last). This is not effective with new
UFS layout policies.

The sorting reorders multiple arguments passed to cp, which may be
undesirable.

Additionally, the comparison function does not induce a total order. Per
POSIX, this causes undefined behaviour in qsort().

NetBSD removed the sorting in 2009.

On filesystems that return directory entries in hash/btree order, sorting by
d_fileno before statting improves performance on large directories. However,
this can only be implemented in fts(3).

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
