* dbxread.c: Add symbol_size to struct dbx_symfile_info.

Add symbol_size and file offsets to struct symloc.
Add static symbol_table_offset, string_table_offset,
file_string_table_offset, next_file_string_table_offset,
last_function_name.
(add_old_header_file):  Convert error() to complain()t.
(dbx_symfile_read):  Get symbol size via the objfile.
Also get symbol_table_offset.
(dbx_symfile_init):  Record symbol size and count via the objfile.
(dbx_next_symbol_text):  Always add file_string_table_offset when
accessing string table.
(read_dbx_symtab):  Initialize file_string_table_offset to 0.
(SET_NAMESTRING):  Use the offset.
(end_psymtab):  Large kludge to determine addresses where source
files start and end (for the psymtab header).
(psymtab_to_symtab_1):  Set file_string_table_offset before reading.
Get this, symbol size, and symbol offset, from psymtab.
(read_ofile_symtab):  Don't back up one symbol for Solaris2.
Patch up last_source_start_addr if zero in N_SO.
(process_one_symbol):  Add variable function_start_offset.
( "", N_FUN, N_LBRAC, N_RBRAC, N_SLINE):  Add ifdef for
BLOCK_ADDRESS_FUNCTION_RELATIVE.
( "", N_OBJ, N_OPT):  Ignore.
(elfstab_build_psymtabs):  New function to read stabs out of
an ELF file.

* Makefile.in:  Accept $(BISON) even though we really want $(YACC).
(gdb):  use GLOBAL_CFLAGS when linking, too.
* partial-stab.h (N_UNDF):  Deal with Sol2 relative stringtab offsets.
(N_OBJ, N_OPT):  Ignore.
('f', 'F'):  Save last function name.

* symfile.h:  Prototype elfstab_build_psymtabs.
* symfile.c:  Add almost-OK debug versions of add_psymbol_*to_list.

* xm-sysv4.h:  Add <limits.h> to avoid conflicting defns in defs.h.
