Fix GC_scratch_alloc and GC_get_maps invocations to prevent SEGV
(if out of memory) * dyn_load.c (GC_register_dynamic_libraries): If GC_scratch_alloc fails (returns null) then abort (with the appropriate message) instead of causing SEGV. * os_dep.c (GC_dirty_init): Likewise. * headers.c (GC_init_headers): Report error and exit if GC_scratch_alloc fails. * include/private/gc_priv.h (GC_scratch_alloc): Improve comment. * os_dep.c (GC_print_address_map): If GC_get_maps return null then print the appropriate message (instead of passing null to GC_err_puts thus causing SEGV).
