The single-line macro argument parsing was completely broken as a
comma would not be recognized as an argument separator.
In the process of fixing this, make a fair bit of code cleanups.
Note: reverse tokens for smacro->expansion doesn't actually make any
sense anymore, might reconsider that.
This checkin also removes the distinction between "magic" and plain
smacros; the only difference is which specific expand method is being
invoked.
Finally, extend the allocating-string functions such that *all* the
allocating string functions support querying the length of the string
a posteori.

New macro which defines the offset on an object rather than a
type. This macro, as far as I know, ought to be fully portable, unlike
the fallback version of offsetof().

Make strlist_free() take a pointer to a pointer, so we can set it to
NULL.
Buffer warnings on a strlist until we either get an error or we are in
pass 2. Hopefully this should let us get rid of a lot of the ERR_PASS*
bullshit, which far too often causes messages to get lost.
asm/labels.c contains one example of a warning that cannot be made
correct with a specific pass number.

Make it a selectable option at allocation time if a strlist should
contain only unique strings or not. If not, we omit the hash table and
strlist_find() will not do anything.
Add printf()-style functions to a strlist.

The currently-unused strtbl was basically a slightly different version
of strlist, with the find and linearize capabilities. Merge these two
together by augmenting strlist to have the same capabilities.

Add binary key support to the hash table interface. Clean up the
interface to contain less extraneous crud.

Use a hash table to enforce uniqueness in a string list. It is still
an ordered list, however, and can be walked in insertion order.
