80cb6ba927 Eliminate the RELOH2 relocation, as it never worked --- the address would be 
calculated incorrectly because of overflow errors.

Replace it with an extended RELOPPC relocation which understands addis/ori
pairs; add an la pseudoop to the assembler which generates these and the
appropriate relocation. Make good.

5e84be70fd Massive ackbuilder refactor --- cleaner and more expressive. Lists 
are automatically flattened (leading to better build files), and the
list and filename functions are vastly more orthogonal.

ef8e6e25e0 Fix a whole pile of issues related to the failed attempt to increase 
the number of types of relocation possible in the object file. (Now,
hopefully, working.)

Also change the object serialiser/deserialiser to never try to read or
write raw structures; it's way safer this way and we don't need the
performance boost any more.

0131ca4d46 Delete 689 undead files. 
These files "magically reappeared" after the conversion from CVS to
Mercurial.  The old CVS repository deleted these files but did not
record *when* it deleted these files.  The conversion resurrected these
files because they have no history of deletion.  These files were
probably deleted before year 1995.  The CVS repository begins to record
deletions around 1995.

These files may still appear in older revisions of this Mercurial
repository, when they should already be deleted.  There is no way to fix
this, because the CVS repository provides no dates of deletion.
