now that their size is only two pointers. This eliminates a lot of calls
to Lst_Init and from there to malloc together with many calls to
Lst_Destroy (in places where the list is obviously empty). This also
reduces the chance to leave a list uninitilized so we can remove more
NULL pointer checks and probably eliminates a couple of memory leaks.
only in a couple of places and all of them except for one were easily
converted to use Lst_First/Lst_Succ. The one place is compatibility
mode in job.c where the it was used to advance to the next command on
each invocation of JobStart. For this case add a pointer to the node to
hold the currently executed command.
requires to make a copy of the filename in ReadMakefile and to duplicate
two small functions in suff.c. This hopefully will go away when everything
is constified.

of the .SHELL target. Formerly it used to select the shell with the
longest common trailing substring, so that bash would select sh, but pocsh
would select csh. Now an exact match is required so that specifying bash
without also giving a path and the other keywords will give an error.

versions of the structure definition for this: one with const char
pointers, because otherwise gcc won't let us initialize the fields with
constant strings, and one without the const, because we need to work
with the structure.
the semantic of Lst_Datum which formerly returned NULL when the argument
node was NULL. There was only one place in the source that relied on this
so change that place.
rid of a lot of uneccesary casts and temporary variables that have just
obfuscated the code. This also let's us implement a couple of the one-
liner list functions as macros (the first one is Lst_IsEmpty) and
simplify life once we start to throw consts on the code.
uses the brk_string function to parse the line. That function uses static
storage for both the expanded string and the returned argv[] vector.
The JobParseShell function simply stored away pointers into this static
storage. On the next use of something like ${FOO:O} this storage would
get overwritten with fatal results.
This also allows us to make the shells[] array const bringing us one step
further in making make WARNS=4 ready.
