12f2bb5262 Serialize accesses to submodule hash tables.
Fixes <https://bugs.gnu.org/30602>.

Previously, when compiling files in parallel like Guix does, threads
would be concurrently inserting, rehashing, and reading the submodule
hash table of module ().  Thus, some threads would sometimes see an
inconsistent state, leading to errors such as:

  Module named (system repl debug) does not exist

* module/ice-9/boot-9.scm (call-with-module-autoload-lock): Move higher
in the file.
(module-name): Use it around call to 'nested-define-module!'.
(resolve-module): Wrap the whole thing in 'call-with-module-autoload-lock'.

498f3f9568 Avoid stacks in dynamically-bound values
* libguile/dynstack.h:
* libguile/dynstack.c (scm_dynstack_find_old_fluid_value): New
  function.
* libguile/fluids.c (saved_dynamic_state_ref): New helper.
  (scm_fluid_ref): Fix docstring.
  (scm_fluid_ref_star): New function allowing access to previous values
  for a fluid.
  (scm_dynamic_state_ref): New internal function.
* libguile/fluids.h: Add scm_fluid_ref_star and scm_dynamic_state_ref.
* libguile/stacks.c (scm_stack_id): Adapt to %stacks not being a chain.
* libguile/throw.c (catch, throw_without_pre_unwind): Adapt to
  %exception-handlers not being a chain.
* module/ice-9/boot-9.scm (catch, dispatch-exception): Instead of having
  %exception-handlers be a chain, use fluid-ref* to access the chain
  that is in place at the time the exception is thrown.  Prevents
  unintended undelimited capture of the current exception handler stack
  by a delimited "catch".
  (%start-stack): Similarly, don't be a chain.
* module/system/repl/debug.scm (frame->stack-vector):
* module/system/repl/error-handling.scm (call-with-error-handling):
* module/ice-9/save-stack.scm (save-stack): Adapt to %stacks not being a
  chain.
* test-suite/tests/exceptions.test ("delimited exception handlers"): Add
  tests.
* doc/ref/api-control.texi (Fluids and Dynamic States): Add docs.

a000e5c38d Enable interrupts only when running thread body
* libguile/threads.c (really_launch): Start threads with asyncs
  blocked.
* module/ice-9/threads.scm (call-with-new-thread): Unblock asyncs once
  we have the bookkeeping sorted out.  Don't use
  with-continuation-barrier; it's not needed.  Print nice thread
  backtraces.

6dd87f4d8c Add suspendable-continuation?
* doc/ref/api-control.texi (Prompt Primitives): Document
  suspendable-continuation?.
* libguile/control.c (scm_suspendable_continuation_p): New procedure.
  (scm_init_ice_9_control): New extension procedure, defines
  suspendable-continuation?.
  (scm_init_control): Register scm_init_ice_9_control.
* libguile/eval.c (eval):
* libguile/throw.c (catch):
* libguile/continuations.c (scm_i_make_continuation): Restore resumable
  prompt cookie after continuation invocation.
* libguile/vm.c (scm_call_n): Arrange to set resumable_prompt_cookie
  during invocation of VM.
* libguile/vm.h (struct scm_vm): Add resumable_prompt_cookie member.
* module/ice-9/control.scm: Export suspendable-continuation?.
* test-suite/tests/control.test ("suspendable-continuation?"): New
  test.

7184c176b4 with-dynamic-state compiler and VM support

  pop-dynamic-state.
* libguile/vm-engine.c (push-dynamic-state, pop-dynamic-state): New
  opcodes.
* module/ice-9/boot-9.scm (with-dynamic-state): New definition in Scheme
  so that the push-dynamic-state and pop-dynamic-state always run in the
  VM.
* module/language/cps/compile-bytecode.scm (compile-function):
* module/language/cps/effects-analysis.scm:
* module/language/cps/types.scm:
