There are two goals: one, to use less memory per dynamic state in order
to allow millions of dynamic states to be allocated in light-weight
threading scenarios. The second goal is to prevent dynamic states from
being actively mutated in two threads at once. This second goal does
mean that dynamic states object that escape into scheme are now copies
that won't receive further updates; an incompatible change, but one
which we hope doesn't affect anyone.

* module/ice-9/deprecated.scm: Remove all deprecated code. CPP defines
that were not previously issuing warnings were changed so that their
expansions would indicate the replacement forms to use,
e.g. scm_sizet__GONE__REPLACE_WITH__size_t.
The two exceptions were SCM_LISTN, which did not produce warnings
before, and the string-filter argument order stuff.
Drops the initial dirty memory usage of Guile down to 2.8 MB on my
machine, from 4.4 MB.
This allows customizing the reader behavior for a dynamic extent more easily.
* libguile/read.c (scm_read_hash_procedures): Renamed to
`scm_i_read_hash_procedures'.
(scm_i_read_hash_procedures_ref, scm_i_read_hash_procedures_set_x):
New (internal) accessor functions for the fluid.
(scm_read_hash_extend, scm_get_hash_procedure): Use these accessor
functions.
(scm_init_read): Create the fluid, named `%read-hash-procedures' instead of
the previous plain list `read-hash-procedures'.
* test-suite/tests/reader.test: Adapt the "R6RS/SRFI-30 block comment
syntax overridden" test to make use of the fluid.
* module/ice-9/deprecated.scm (read-hash-procedures):
New identifier macro -- backward-compatibility shim.
Signed-off-by: Ludovic Courtès <ludo@gnu.org>
* module/ice-9/boot-9.scm (module-ref-submodule)
(module-define-submodule!): Pull deprecated shims here, as we need
them before loading (ice-9 deprecated). Also bugfix to only define the
module if there is no local variable, even if it is unbound.
* module/ice-9/deprecated.scm: Remove from here.
* module/ice-9/boot-9.scm (*repl-stack*): Instead of repl-level, have a
stack.
(batch-mode?): Change to poke the stack.

method.
* module/system/repl/common.scm (repl-prompt): Update to poke
*repl-stack* to get the level.

appropriately.
* libguile/backtrace.h (scm_the_last_stack_fluid_var)
* libguile/backtrace.c (scm_init_backtrace): No more
scm_the_last_stack_fluid_var. The replacement is to resolve
`the-last-stack' in (ice-9 stack-catch).

the last stack, backtrace the current stack.

helped though.
* module/ice-9/boot-9.scm:
* module/ice-9/deprecated.scm (get-option, for-next-option)
(display-usage-report, transform-usage-lambda): Deprecate these
option-parsing utils. We can revive them in a non-deprecated module if
there is interest, but I suspect there will be no interest.
* module/ice-9/boot-9.scm:
* module/ice-9/scm-style-repl.scm (bad-throw): Move here. This function
was never documented, but has been around since guile-ii. It's not
used with current code though.

* module/ice-9/debugger/commands.scm: Import bad-throw from
scm-style-repl.

(set-module-submodule-binder!): New field on modules.
(make-module, make-autoload-interface): Adapt.

submodule binder before the deprecated look into the obarray.

module-submodules table, instead of looking for bindings in the value
namespace.

(module-define-submodule!): Define deprecated versions of these that
duplicate the submodules table in the normal values namespace, for
back compatibility.
