Revising out-of-memory handling.

We don't want to be aborting on OOM, but throwing an
exception.

* lib.c (alloc_error_s): New symbol variable.
(oom_realloc): Global variable removed.
(oom): New static function.
(chk_malloc, chk_malloc_gc_more, chk_calloc, chk_realloc):
Call oom instead of removed oom_realloc handler.
(env): Throw alloc-error rather than error by calling oom.
(obj_init): Initialize alloc_error_s.
(init): Drop function pointer argument; do not
initialize removed oom_realloc.

* lib.h (alloc_error_s): Declared.
(oom_realloc): Declaration removed.
(init): Declaration updated.

* txr.1: Type tree diagram includes alloc-error.
