(code refactoring)

This commit is intended to simplify GC reinitialization.

* finalize.c [!GC_NO_FINALIZATION] (GC_log_fo_table_size): Likewise.
* finalize.c [!GC_NO_FINALIZATION && !GC_TOGGLE_REFS_NOT_NEEDED]
(GC_toggleref_array_size, GC_toggleref_array_capacity): Likewise.
* fnlz_mlc.c [ENABLE_DISCLAIM] (GC_finalized_kind): Likewise.
* mark.c (GC_mark_stack_size, GC_mark_state, GC_mark_stack_too_small,

* mark.c [PARALLEL_MARK] (GC_first_nonempty): Likewise.
* mark.c [TRACE_BUF] (GC_trace_buf_ptr): Likewise.
* mark_rts.c (n_root_sets, GC_roots_were_cleared,
GC_excl_table_entries): Likewise.
* os_dep.c [MSWIN32 || MSWINCE || CYGWIN32] (GC_n_heap_bases):
Likewise.
* typd_mlc.c (GC_ed_size, GC_avail_descr,
GC_explicit_typing_initialized): Likewise.
* extra/MacOS.c (GC_fo_entries): Remove variable declaration.
* include/private/gc_pmark.h (GC_mark_stack_size,
GC_mark_stack_too_small, GC_mark_state): Likewise.
* include/private/gc_priv.h (GC_n_heap_sects, GC_fo_entries): Likewise.
* include/private/gc_priv.h [USE_PROC_FOR_LIBRARIES] (GC_n_memory):
Likewise.
* include/private/gc_pmark.h (mark_state_t): Move typedef to gc_priv.h.
* include/private/gc_priv.h (_GC_arrays._scratch_end_ptr,
_GC_arrays._scratch_last_end_ptr): Document.
* include/private/gc_priv.h [PARALLEL_MARK] (_GC_arrays): Add
_first_nonempty field.
* include/private/gc_priv.h (_GC_arrays): Add _mark_stack_size,
_mark_state, _mark_stack_too_small, _objects_are_marked, _n_heap_sects,
_n_memory, _fo_entries, _n_root_sets, _excl_table_entries,
_roots_were_cleared, _explicit_typing_initialized, _ed_size,
_avail_descr fields.
* include/private/gc_priv.h [USE_PROC_FOR_LIBRARIES] (_GC_arrays): Add
_n_memory field.
* include/private/gc_priv.h [MSWIN32 || MSWINCE || CYGWIN32]
(_GC_arrays): Add _n_heap_bases field.

&& !GC_TOGGLE_REFS_NOT_NEEDED] (_GC_arrays): Add _toggleref_array_size,
_toggleref_array_capacity fields.

_trace_buf_ptr field.
* include/private/gc_priv.h [ENABLE_DISCLAIM] (_GC_arrays): Add
_finalized_kind field.
