This reverts commit r247274.
As maintainer of sh, I disapprove of this feature addition.
It is too specific and can be done without easily using find(1) or stat(1).
I will add some hints to the test(1) man page shortly.
In general, FreeBSD sh is not the place to invent new shell language
features. This is how it has been maintained and adding features randomly
does not work with that.
The new syntax (e.g. [ FILE1 -ntca FILE2 ]) looks cryptic to me.
access, birth, change and modify times of two files, instead of only
being able to compare modify times. The builtin test in sh(1) will
automagically acquire the same expansion.

For these simple utilities, it doesn't harm to make all global variables
static. In fact, this allows the compiler to perform better forms of
optimisation and analysis.
Convert the tests to the perl prove format.
Remove obsolete TEST.README (results of an old TEST.sh for some old Unices)
and TEST.csh (old tests without correct values, far less complete than
TEST.sh).

More precisely, this gives precedence to an interpretation not using the
'(', ')', '-a' and '-o' in their special meaning, if possible. For example,
it is now safe to write [ "$a" = "$b" ] and assume it compares the two
strings.
The man page already says that test(1) works this way, so does not need to
be changed.
Interpretation of input with more parameters tries a bit harder to find a
valid parse in some cases.
Add various additional test cases to TEST.sh.

"feature" doesn't seem to be in the standards or elsewhere, and
it is against what we are used to in C and sh(1), so put the
paragraph under BUGS.

Remove eaccess(2) absence workaround. Add eaccess(2) checks for FILRD,
FILWR, FILEX and FILEXIST cases.
We cannot MFC this because there is no eaccess(2) in -stable yet.

after making test(1) a sh(1) builtin; sh(1) coredumps when you run
something like this:
sh -c 'test ! `true 1`'
The cause is that the test(1) code totally depends on the presence of
two extra cells at the end of argv that are filled with NULL's. The
reason why the bug hasn't been exposed would be because the C startup
code kindly prepares argv with some extra zeroed cells for a program.
I know this is not the best fix, but since there are argv++'s without
boundary checks everywhere, I'd rather patch it up like this
(preparing a copy of argv with extra NULL's) for the moment.

I don't drop the printf builtin while I'm here because some /etc/rc.*
scripts seem to use it before mounting /usr where printf(1) resides.
