71cb38c340 ar: enable reproducible output by default when invoked as 'ar -s'
ar output is already deterministic by default for ar -q and ar -r, and
when invoked as ranlib. Make ar -s equivalent to ranlib and enable
deterministic output by default in that case too.

32ba4de644 Make code compile when basename() is POSIX compliant.
In addition to the previous change I made to ar.c, pull in another
basename() related fix. This change is similar to the one made to the
ELF Toolchain version of ar, with the difference that the ELF Toolchain
version lacks error handling for the strdup() call.

28c859fd2e Make code compile when basename() is POSIX compliant.
If basename() uses "char *", we shouldn't do the intermediate
assignment, as that field is of type "const char *". Simply call
basename() on the command line argument directly.

25c00d1c25 ar: enable deterministic mode by default
Ar cannot handle UIDs with more than 6 digits, and storing the mtime,
uid, gid and mode provides little to negative value anyhow for ar's
uses. Turn on deterministic (-D) mode by default; it can be disabled by
the user with -U.

c58042ff07 ar: add -U (unique) option to disable -D (deterministic) mode
This is required in order for us to support deterministic mode by
default.  If multiple -D or -U options are specified on the command
line, the final one takes precedence.  GNU ar also uses -U for this.

An equivalent change will be applied to ELF Tool Chain's version of ar.

56f61c7a15 speed up ar(1) on UFS file systems
Fault in the buffer prior to writing to workaround poor performance due
to interaction with kernel fs deadlock avoidance code. See the comment
prior to vn_io_fault_doio() in sys/kern/vfs_vnops.c for details of the
issue.

c4c8403c3f ar: Disallow directory traversal
Set ARCHIVE_EXTRACT_SECURE_SYMLINKS and ARCHIVE_EXTRACT_SECURE_NODOTDOT
as in bsdtar to prevent extraction of archive entries whose pathnames
contain .. or whose target directory would be altered by a symlink.
Also disallow absolute pathnames.

We don't currently provide an option to disable this behaviour (as
bsdtar's -P does). It is unlikely to be a problem in practice for ar(1),
but the -P option is not currently used and available if we want to
consider it for this purpose.

120125784a Add the Clang specific -Wmissing-variable-declarations to WARNS=6.
This compiler flag enforces that that people either mark variables
static or use an external declarations for the variable, similar to how
-Wmissing-prototypes works for functions.

Due to the fact that Yacc/Lex generate code that cannot trivially be
changed to not warn because of this (lots of yy* variables), add a
NO_WMISSING_VARIABLE_DECLARATIONS that can be used to turn off this
specific compiler warning.
