Add option -D for ranlib(1). When -D is speicified, ranlib(1) will generate
a deterministic archive symbol table (i.e. timestamp for the symbol table
member header is set to 0).

Add -D (deterministic) option to ar.
When set, it forces all timestamps and owners to zero and
modes to 0644. Useful for producing libraries that are
bitwise identical across multiple build runs.

Removed ar(1)'s support for compressed archives. This change removes
ar(1)'s dependencies on compressor libraries -lz, -lbz2 and -llzma and
fixes building HEAD on some versions of FreeBSD[78]. Option -j and -z
is now accepted but ignored.

Compressed ar(1) archives are not useful without a ld(1) that can read
them. Also, the current ar(1) compression scheme prevents random
access of archive members and needs to be redesigned anyway.

mdoc: order prologue macros consistently by Dd/Dt/Os

Although groff_mdoc(7) gives another impression, this is the ordering
most widely used and also required by mdocml/mandoc.

GNU ar did NOT implment option -q as a synonym of -r as the manual
page stated, thus BSD ar(1) option -q, which was implemented based on
the GNU ar manual page, turns out to be incompatible with GNU ar -q.

This change will make BSD ar(1) -q a *REAL* GNU ar -q:

1. It will update symbol table. (same as unfixed version)
2. It will NOT compare new members spcified in the command line args
with existing members, instead, append them directly.
