section in an ELF file, override a symbol's ECOFF section with its
ELF section. Also, fix stabs continuation where a stabs string
continues for more than one continuation.
Only worked if the first element in the list was
being deleted.
o When MAINLINE (reading main objectfile and need to
clear out old data), change elfread.c so that the
psymbol table is emptied once (in elf_symfile_read)
instead of multiple times in each *_read_psymtab
function.
o For elf_symfile_read, load dwarf2 symbols last
(so that they are searched for first).
o In mdebug_psymtab_read, delete check to see if
symbols for current source file already loaded.
Test doesn't work for .h files. Above change

(c) is new to avoid mistaking a return from a signal handler into

gaps due to alignment of structure members.
* symfile.h (INLINE_ADD_PSYMBOL, ADD_PSYMBOL_TO_LIST,
ADD_PSYMBOL_ADDR_TO_LIST): Remove. Real world tests show no
performance improvements by inlining via complicated macros and
they just make gdb larger and harder to maintain.
