For Sunos 4.x targets, enable gdb to set breakpoints in shared
library functions before the executable is run. Retrieve dynamic
symbols from stripped executables.
* symtab.h (minimal_symbol_type): Add mst_solib_trampoline type.
* parse.c (write_exp_msymbol), symmisc.c (dump_msymbols),
symtab.c (list_symbols): Handle mst_solib_trampoline.
* minsyms.c (lookup_minimal_symbol): Handle mst_solib_trampoline
for all targets, remove IBM6000_TARGET dependencies.
* dbxread.c (read_dbx_dynamic_symtab): New function.
* dbxread.c (dbx_symfile_read): Use it.
* dbxread.c (SET_NAMESTRING): Set namestring to
"<bad string table index>" instead of "foo" if the string index is
corrupt.
* xcoffread.c (read_xcoff_symtab): Use mst_solib_trampoline instead
of mst_unknown.
* symtab.c (list_symbols): Take from_tty as parameter and pass it
to break_command. Handle mst_file_* minimal symbol types.
