Slight optimizations: instead of storing archive members, just keep
the modification time, as we don't care for the rest of the archive
information. Lazily compute mtime, stash ascii date instead, and convert
to mtime when needed (storing an out_of_date value to mark the unconverted
values).
Archive handling is atrocious and need some clean-up.
Thanks to miod@ who took the time to review those patches.

Replace the time stamp hash in dir.c with an open hashing structure.
In doing so, remove some nasty casts, simplify code a bit:
Dir_MTime can return a modification time, since make does not make
a distinction between out-of-date and non-existent files.

open hashing.
An interesting optimization is that the open hashing interface is more
fine-grained, hence we can compute the correct hash value at the start
of Dir_FindFile, and reuse it for each hash structure into which we look
(the effect is measurable on large directories along with objdir/VPATH).
Remove a few unnecessary Lst_Open/Lst_Close that serve no purpose except
obfuscating the code.
The interface to dir.h changes slightly, hence tedious includes changes...

the disk or from a cache.
- use it in Dir_AddDir, and directly to set up dot.
- change Dir_AddDir to use string intervals, as this simplifies
dependend functions.
- set up an open-hashing cache for opened directory names.
- add_dirpath() function in main, to simplify code.
- simplify cleaning-up directories, as Dir_ClearPath is overkill.

Scrap the list of all targets: it only slows make down.
The only visible difference is that the list of all targets is not
shown in order when debugging.

iterate_words: light-weight equivalent to brk_string,
which does not need to copy the string, and does not do \ interpretation
which are only needed for the string.
escape_dup: handles escape sequence in a systematic way.
This speeds up variable modifiers.
This also makes .for loops more consistent, as they use the same definition
of `a word' as the rest of make.

- UNUSED macro that expands to __attribute__((unused)) for gcc
- move rcsid around so that they can be tagged UNUSED.
- activate -Wunused.
- use UNUSED instead of kludgy junk for function arguments.
- add extern to all extern prototypes.
- update comments in lst.h.
- clean up var.c a little bit, constifying arguments, updating comments...

by Solar Designer.

non-MII 21143-based cards work. The sync just fixes the LED handling on these
kinds of adapters.

This should restore the tree to build status, even though patches are
still pending.

Use the new interface to call safe mkstemp or mkdtemp when available.

o fix typo in getsid() that broke getsid(pid) where pid != 0
o cause getsid() and getpgid() to return EPERM if requesting the
id of a session/process group not in the current session
o check for NULL session in getsid() for exiting processes

- only the binutils package (no gdb here)
- don't import libiberty and texinfo, they are elsewhere
- remove all .info* generated files
