* stabsread.c (resolve_symbol_reference): Return 1 on success, 0 on
failure.
* (define_symbol): Check return value from resolve_symbol_reference,
and drop symbol if it fails.

* stabsread.c: Make all complaints static.
* Fix formatting of live range splitting code.
* (resolve_symbol_reference define_symbol resolve_live_range): Change
errors to complaints so that bad live range symbols won't abort the
entire symbol table. Handle errors by aborting just the current
symbol.
* (ref_init): Goes away. Folded into ref_add().
* (REF_MAP_SIZE): Put parens around parameter so that args like
`1 + 2' get handled correctly (yes, this was a real bug).
* (ref_add): Remove check for allocation failures. Not necessary
when using xrealloc(). Fix pointer arithmetic problem when clearing
memory. This and the previous patch prevent random SEGV's when there
are lots of live range symbols.

* remote-rdi.c: Prevent multiple attempts to close the remote
