part). Archive handling was broken at least since the move from BSD ar/ranlib
to GNU binutils because of the different archive format. This rewrite fixes
this by making make to carry around the defines for all formats (it supports)
so it can support all of them independent of the actually used one. The
supported formats are: traditional BSD (this seems to come from V7 at least,
short names only and __.SYMDEF), BSD4.4 (long names with #1/ and __.SYMDEF)
and SysV (extra name table and //). The only format not supported are broken
traditional archives where the member names are truncated to 15 characters.
Errors in the archive are not ignored anymore, but cause make to stop with
an error message. The command line option -A causes these errors to become
non-fatal. This is almost compatible with previous usage except for the
error message printed in any case.
Use a type-safe intrusive list for the archive cache.

A Path is now a TAILQ of PathElements each of which just points to
a reference counted directory. Rename all functions dealing with Paths
from the Dir_ prefix to a Path_ prefix.

headers that they need to compile (just with an empty .c file). Sort
includes alphabetically where apropriate and fix some duplicate commenting
for struct Job, struct GNode and struct Shell by removing one version and
inlining the comments into the structure declaration (the comments have been
somewhat outdated).
This patch does not contain functional changes (checked with md5).
