Fix spurious `throw from within critical section' errors
The crux of this problem was that the thread doing a throw, and so checking scm_i_critical_section_level, was different from the thread that was in a critical section. * libguile/async.h (scm_i_critical_section_level): Removed, replaced by per-thread critical_section_level. (SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END): Use per-thread critical_section_level. * libguile/continuations.c (scm_dynthrow): Check per-thread critical_section_level. * libguile/threads.c (guilify_self_1): Init per-thread critical_section_level. (scm_i_critical_section_level): Removed. * libguile/threads.h (scm_i_thread): New critical_section_level field. * libguile/throw.c (scm_ithrow): Check per-thread critical_section_level.
