From jilles: POSIX requires that a script set `OPTIND=1` before using
different sets of parameters with `getopts`, or the results will be
unspecified.
The specific problem observed here is that we would execute `man -f` or
`man -k` without cleaning up state from man_parse_args()' `getopts`
loop. FreeBSD's /bin/sh seems to reset OPTIND to 1 after we hit the
second getopts loop, rendering the following shift harmless; other
/bin/sh implementations will leave it at what we came into the loop at
(e.g., bash as /bin/sh), shifting off any keywords that we had.

If MK_DEBUG_FILES=no then the Clang link rule has clang as .TARGET,
rather than clang.full, causing the implicit ${CFLAGS.${.TARGET:T}} to
be CFLAGS.clang, and thus pull in flags intended for when your compiler
is Clang, not when linking Clang itself. This doesn't matter if your
compiler is in fact Clang, but it breaks using GCC as, for example,
bsd.sys.mk adds -Qunused-arguments to CFLAGS.clang. This is seen when
trying to build a bootstrap toolchain on Linux where GCC is the system
compiler.
Thus, introduce a new internal NO_TARGET_FLAGS variable that is set by
Clang to disable the addition of these implicit flags. This is a bigger
hammer than necessary, as flags for .o files would be safe, but that is
not needed for Clang.
Note that the same problem does not arise for LDFLAGS when building LLD
with BFD, since our build produces a program called ld.lld, not plain
lld (unlike upstream, where ld.lld is a symlink to lld so they can
support multiple different flavours in one binary).

This issue did not affect the bc program, since it does not use dc as
an back-end to actually perform the calculations as was the case with
the traditional bc and dc programs.
The major number has been bumped due to Windows support that has been

The RCS IDs have been retired as of the move to git, so on 14-CURRENT

This fortune brought to you by:
$FreeBSD$
While faintly amusing the first time, this might just cause confusion

Therefore it seems prudent to get rid of it.
MFC: Not to 11-STABLE or 12-STABLE.
Currently running `truss -a -e` does not decode any
argument values for freebsd32_* syscalls (open/readlink/etc.)
This change checks whether a syscall starts with freebsd{32,64}_ and if
so strips that prefix when looking up the syscall information. To ensure
that the truss logs include the real syscall name we create a copy of
the syscall information struct with the updated.
The other problem is that when reading string array values, truss
naively iterates over an array of char* and fetches the pointer value.
This will result in arguments not being loaded if the pointer is not
aligned to sizeof(void*), which can happens in the compat32 case. If it
happens to be aligned, we would end up printing every other value.
To fix this problem, this changes adds a pointer_size member to the
procabi struct and uses that to correctly read indirect arguments
as 64/32 bit addresses in the the compat32 case (and also compat64 on
CheriBSD).
The motivating use-case for this change is using truss for 64-bit
programs on a CHERI system, but most of the diff also applies to 32-bit
compat on a 64-bit system, so I'm upstreaming this instead of keeping it
as a local CheriBSD patch.

This change is a refactoring cleanup to improve support for compat32

Glibc's stdlib.h defines various prototypes for GNU extensions that take
a locale_t. Newer versions use locale_t directly and include an internal
bits/types/locale_t.h in order to get its definition, but older versions
include xlocale.h for that, for which our bootstrap version is empty.
Moreover it expects to use the glibc-specific __locale_t type. Thus,
provide dummy definitions of both types in order to ensure the
prototypes don't give any errors, and guard against the header being
inadvertently included between the bootstrapping namespace.h and
un-namespace.h, where locale_t is #define'd.
This header is not used when bootstrapping on FreeBSD and exists solely
to stub out glibc's, so this should have no impact on FreeBSD hosts.

The basic issue here is that grep, when given -m 1, would stop all
line processing once it hit the match count and exit immediately. The
problem with exiting immediately is that -A processing only happens when
subsequent lines are processed and do not match.
The fix here is relatively easy; when bsdgrep matches a line, it resets
the 'tail' of the matching context to the value supplied to -A and
dumps anything that's been queued up for -B. After the current line has
been printed and tail is reset, we check our mcount and do what's
needed. Therefore, at the time that we decide we're doing nothing, we
know that 'tail' of the context is correct and we can simply continue
on if there's still more to pick up.
With this change, we still bail out immediately if there's been no -A
flag. If -A was supplied, we signal that we should continue on. However,
subsequent lines will not even bothere to try and process the line. We
have reached the match count, so even if the next line would match then
we must process it if it hadn't. Thus, the loop in procfile() can
short-circuit and just process the line as a non-match until
procmatches() indicates that it's safe to stop.
A test has been added to reflect both that we should be picking up the
next line and that the next line should be considered a non-match even
if it should have been.

The null pattern semantics were terrible because I tried to match gnugrep,
but I got it wrong. Let's unwind that:
- The null pattern should match every line if neither -w nor -x.
- The null pattern should match empty lines if -x.
- The null pattern should not match any lines if -w.
The first two will stop processing (shortcut) even if additional patterns
are specified. In any other case, we will continue processing other
patterns. If no other patterns are specified beside a null pattern, then
we match if neither -w nor -x or set and do not match if either of those
are specified.
The justification for -w is that it should match on a whole word, but the
null pattern deos not have a whole word to match on.
Empty pattern files should never match anything, and more importantly, -v
should cause everything to be written.

This test attempts to use \t (tab intended) in a grep expression. With the
former /usr/bin/grep (i.e. gnugrep), this was interpreted as a literal 't'.
The expression would work anyways because the tr(1) usage would ultimately
replace all of the spaces with a single newline, and they would match the
paths whether they were correctly fromatted or not.
Current /usr/bin/grep (i.e. bsdgrep) is less-tolerant of ordinary-escapes, a
property of the underlying regex(3) engine, to make it easier to identify
when stuff like this happens. In-fact, this expression broke after the
switch happened.
This revision does the bare basics to fix the usage by using a printf to get
a literal tab character to insert into the expression. It also swaps out the
manual insertion of the line prefix into the grep expression by pulling
that part out of $sep and reusing it for the leading path.
The secondary issue was the tr(1) usage, since tr would only replace the
first character of string1 with the first character of string2. This has
instead been replaced by a sed expression, which similary understands \n to
be a newline on all supported versions of FreeBSD. Each path now gets
prefixed with the appropriate context that should be there (i.e. numeric
sequence followed by a tab).

As suggested in D27598. This also supports MK_WERROR.clang=no and
MK_WERROR.gcc=no to support the existing NO_WERROR.<compiler> uses.

sockstat can "hang" on getpwuid() calls in situations when FreeBSD
is joined to a directory service (AD/LDAP etc) and the directory
service fail to answer in a timely manner when trying to resolve
numeric UIDs to user names.

FreeBSD has used ELF binaries/libraries for decades, but still has some
support for legacy a.out binaries. Portions of this have been retired
over time, but support remained in ldd, ldconfig, and gprof.
Retire gprof support; if anyone needs to do development on a.out
binaries still they will be best served by installing a full FreeBSD 2.x
or other obsolete version in a jail.
Kernel support for executing a.out binaries is unchnaged.

When exporting a variable we correctly check all the preconditions that
could make setenv(3) fail. Checking the setenv(3) return value seems
redundant, but given that login(1) is critical, it doesn't hurt to have
a post-check.
This change is based on the "Principles of Secure Coding" course by
Matthew Bishop, PhD., which specifically discusses this code in FreeBSD.
(This change redoes r368776 due to a silly mistake)
