fix potential integer overflows in memory allocation (mostly for pedagogical
purposes, these are unlikely to overflow in practice)
move the rest of lst.lib stuff into its own directory.

while there, clean up includes.
use strtoll for ar timestamps (pretty much unused in reality, more
standard conforming than anything)
use idea from Todd to adapt to time_t being 32 bits OR 64 bits
(pedantically correct: INT_MIN would work just fine up to 1910 or so...)
okay millert@, gone thru a make build.

- allow variables in SysV modifiers, as requested by matthieu@
(since recursive variables are an extension, this just extends the
extension)
- variation on :Q called :QL (quote list), which does quote every character
EXCEPT for whitespace. e.g.,
toto:
@for i in ${VAR:QL} ...

- expand commands earlier, so that we can eventually scan them to take
smarter decisions.
- clean up the select() mask code and rename variables to sensible things.
- quite a few minor renames for readability
- erecalloc
- clean up wait status handling, do not try to rebuild wait status, but
instead parse it early and deal with the parsed code.
tested by lots of people, thanks guys!

more explicit/more consistent names.

rescinded 22 July 1999. Proofed by myself and Theo.

- cut up those huge include files into separate interfaces for all modules.
Put the interface documentation there, and not with the implementation.
- light-weight includes for needed concrete types (lst_t.h, timestamp_t.h).
- cut out some more logically separate parts: cmd_exec, varname, parsevar,
timestamp.
- put all error handling functions together, so that we will be able to
clean them up.
- more systematic naming: functioni to handle interval, function to handle
string.
- put the init/end code apart to minimize coupling.
- kill weird types like ReturnStatus and Boolean. Use standard bool (with a
fallback for non-iso systems)
- better interface documentation for lots of subsystems.
As a result, make compilation goes somewhat faster (5%, even considering
the largish BSD copyrights to read). The corresponding preprocessed
source goes down from 1,5M to 1M.
A few minor code changes as well: Parse_DoVar is no longer destructive.
Parse_IsVar functionality is folded into Parse_DoVar (as it knows what an
assignment is), a few more interval handling functions. Avoid calling
XXX_End when they do nothing, just #define XXX_End to nothing.
Parse_DoVar is slightly more general: it will handle compound assignments
as long as they make sense, e.g., VAR +!= cmd
will work. As a side effect, VAR++=value now triggers an error
(two + in assignment).
- this stuff doesn't occur in portable Makefiles.
- writing VAR++ = value or VAR+ +=value disambiguates it.
- this is a good thing, it uncovered a bug in bsd.port.mk.
Tested by naddy@. Okayed millert@. I'll handle the fallback if there is
any. This went through a full make build anyways, including isakmpd
(without mickey's custom binutils, as he didn't see fit to share it with me).
