b791fbe630 META MODE: Don't create .meta files when symlinking sources into the obj directory.
Tracking these leads to situations where meta mode will consider the
file to be out of date if /bin/sh or /bin/ln are newer than the source
file.  There's no reason for meta mode to do this as make is already
handling the rebuild dependency fine.

8ef0ae8a8f sh: Make struct arglist an array instead of a linked list.
This simplifies the code (e.g. allowing use of qsort(3) instead of a
hand-rolled mergesort) and should have better cache properties.

The waste of unused args arrays after resizes is approximately the same as
the savings from getting rid of the next pointers.

At the same time, remove a piece of global state and move some duplicated
code into a function.

3a845236df Start using the fact that SUBDIR.yes is added to SUBDIR
and move from the pattern of:

.if ${MK_FOO} != "no"
SUBDIR+= bar
.endif

to

SUBDIR.${MK_FOO}+= bar

since we know that MK_FOO is always either yes or no and the latter
form is easier to follow and much shorter. Various exception to this
pattern dealt with on an ah-hoc basis.

a0abe9cd7e Merge additional testcases and improvements to bin/ls/ls_tests from
^/user/ngie/more-tests.

- Additional testcases added:
-- ls -D
-- ls -F
-- ls -H
-- ls -L
-- ls -R
-- ls -S
-- ls -T
-- ls -b
-- ls -d
-- ls -f
-- ls -g
-- ls -h
-- ls -i
-- ls -k
-- ls -l
-- ls -m
-- ls -n
-- ls -o
-- ls -p
-- ls -q/ls -w
-- ls -r
-- ls -s
-- ls -t
-- ls -u
-- ls -y
- Socket file creation is limited to the ls -F testcase, greatly speeding up
  the test process
- The ls -C testcase was made more robust by limiting the number of columns
  via COLUMNS and by dynamically formulating the columns/lines.
- Add `atf_test_case` before all testcase `head` functions.

d358fa780b wordexp: Rewrite to make WRDE_NOCMD reliable.
Shell syntax is too complicated to detect command substitution and unquoted
operators reliably without implementing much of sh's parser. Therefore, have
sh do this detection.

While changing sh's support anyway, also read input from a pipe instead of
arguments to avoid {ARG_MAX} limits and improve privacy, and output count
and length using 16 instead of 8 digits.

The basic concept is:
execl("/bin/sh", "sh", "-c", "freebsd_wordexp ${1:+\"$1\"} -f "$2",
    "", flags & WRDE_NOCMD ? "-p" : "", <pipe with words>);

The WRDE_BADCHAR error is still implemented in libc. POSIX requires us to
fail strings containing unquoted braces with code WRDE_BADCHAR. Since this
is normally not a syntax error in sh, there is still a need for checking
code in libc, we_check().

The new we_check() is an optimistic check that all the characters
  <newline> | & ; < > ( ) { }
are quoted. To avoid duplicating too much sh logic, such characters are
permitted when quoting characters are seen, even if the quoting characters
may themselves be quoted. This code reports all WRDE_BADCHAR errors; bad
characters that get past it and are a syntax error in sh return WRDE_SYNTAX.

Although many implementations of WRDE_NOCMD erroneously allow some command
substitutions (and ours even documented this), there appears to be code that
relies on its security (codesearch.debian.net shows quite a few uses).
Passing untrusted data to wordexp() still exposes a denial of service
possibility and a fairly large attack surface.

62c3711632 sh: Add set -o nolog.
POSIX requires this to prevent entering function definitions in history but
this implementation does nothing except retain the option's value. In ksh88,
function definitions were usually entered in the history file, even when
they came from ~/.profile and the $ENV file, to allow displaying their
definitions.

This is also the first option that does not have a letter.

d0b0ac182d sh: Don't create bad parse result when postponing a bad substitution error.
An invalid substitution like ${var@} does not cause a parse error but is
stored in the intermediate representation, to be written as part of the
error message. If there is a CTL* byte in the stored part, this confuses
some code such as the code to skip an unused alternative such as in
${var-alternative}.

To keep things simple, do not store CTL* bytes.
