more assorted script enhancements

merging back my devel changes (anchor environments)

merging changes from devel branch; new boot files

bring revisions from the vendor branch to the trunk

merged pending changes into main trunk; see HISTORY; new binfiles!!

merging last bits before 110.27 code freeze

changes to modmap generator and CM tool parameter mechanism (see HISTORY)

merging back development branch blume_devel_v110p26p1_3...
This involves changes to CM and the removal of CMStaticEnv from
the compiler.  See the HISTORY file for more information.

merging back blume_devel_v110p26p1_1

merging back changes from blume_devel_v110_26_2

- size info in BOOTLIST
     * no fixed upper limits for number of bootfiles or length of
       bootfile names in runtime
     * falling back to old behavior if no BOOTLIST size info found
- allocation size heuristics in .run-sml
     * tries to read cache size from /proc/cpuinfo (this is important for
        small-cache Celeron systems!)
- install.sh robustified
- CM manual updates
- paranoid mode
     * no more CMB.deliver() (i.e., all done by CMB.make())
     * can re-use existing sml.boot.* files
     * init.cmi now treated as library
     * library stamps for consistency checks
- sml.boot.<arch>-<os>/PIDMAP file
     * This file is read by the CM startup code.  This is used to minimize
       the amount of dynamic state that needs to be stowed away for the
       purpose of sharing between interactive system and user code.
- CM.Anchor.anchor instead of CM.Anchor.{set,cancel}
     * Upon request by Elsa.  Anchors now controlled by get-set-pair
       like most other CM state variables.
- Compiler.CMSA eliminated
     * No longer supported by CM anyway.
- fixed bugs in pickler that kept biting Stefan
     * past refs to past refs (was caused by the possibility that
       ad-hoc sharing is more discriminating than hash-cons sharing)
     * integer overflow on LargeInt.minInt
- ml-{lex,yacc} build scripts now use new mechanism
  for building standalone programs
- fixed several gcc -Wall warnings that were caused by missing header
  files, missing initializations, etc., in runtime (not all warnings
  eliminated, though)

CM changes: standalone builds, better CMB.make/deliver, general improvements

tool plugins implemented

more careful cleaning when seeing/creating stable libs

conserve_memory off by default; done anyway at bootstrap time; docu update

pickle dropper

Tools cleaned up

relative osstrings; groupsOf

added cleanGroup after reading stable library

smlinfo registry handled better; dia test; manual updates

minimal/full CM separated

small change to SafeIO; cosmetic fix of master-slave interrupt handling; doc

stable loading is now self-contained; more cycle reporting

symval added; getterSetter changed to { get, set }

some small bugs squashed

new stable format + improved recompile/link (in progress, not working yet)

old-style operators recognized (with warning message)

just syncing; this version does not work

bug in cm.lex fixed

aliases eliminated

more bugs/problems eliminated from the list...

handling of cwd corrected

more inching towards a usable system

bootstrapping now working (it seems)

bootstrapping works now (mainly); PathConfig code cleaned majorly

error message improved; handling of corenv corrected in btcompile

autoloading added

a host of changes related mostly to pathname handling

various changes in pathname handling etc.

wrapped privileges cleaned up; Overview updated

error flag in source cancelled; IO vs. interrupts handled more robustly

groups not stabilizable by themselves (sucked into surrounding stable library)

SymVal implemented

stablefile format enhanced; bootstrap compiler shows signs of life

bootstrap compiler half-working

first steps towards bootstrap compiler

some cleanup; pathconfig modes added; grammar modified (privileges)

resynchronization facility added (#line)

stabilization code properly hooked in

stabilization code working but only flimsily hooked up

stabilization code completed -- still needs to be hooked up

dyn-tstamp eliminated; more fiddling with sharing (now checked statically)

recompile and exec mostly working (probably still bugs in the details)

finished recomp.sml; now only need to put the pieces together

persistent state/error handling bogosity fixed

most of recompilation/execution machinery in place

first steps towards make/recompile and stable libraries

skeleton type simplified; improved conversion, etc.

full dependency analysis (hopefully) in place

stdtool as function; better depend. graphs, group export grammar fixed

GroupReg added; bad error msg behavior fixed

early beginning of dep. analysis

stdtool; yacc/lex/burg tools; some odd fixes here and there

skeleton stuff added (works); error messages improved; SML export analysis

stage0 -- links fine (for testing); parses correctly (apparently)

checking for group cycles implemented (with nicely formatted error message)

semant/members.sml should be fairly complete now

front end completed (modulo bugs)

more fleshing out semant

some small changes + re-commit after server crash(?)

laid foundations for lexer, parser, basic path handling
