* dbxread.c (stabs_data): New static variable.
(fill_symbuf): Support an in-memory buffer for stabs data.
(stabs_seek): New function.
(dbx_psymtab_to_symtab): Relocate the stabs data if necessary.
(read_ofile_symtab): Use stabs_seek.
(elfstab_build_psymtabs): Take an asection* instead of
an offset and size. Relocate the stabs data if necessary.
Save the section* for dbx_psymtab_to_symtab.
* dwarf2read.c: Add section variables for each debug section.
(dwarf2_locate_sections): Fill them in.
(dwarf2_read_section): Take an asection* argument.
Relocate the section contents if necessary.
(dwarf2_build_psymtabs, dwarf2_build_psymtabs_easy): Update callers.
* dwarf2cfi.c (parse_frame_info): Take a section argument and pass
it to dwarf2_read_section.
(dwarf2_build_frame_info): Update callers.
* elfread.c (elf_symfile_read): Update call to
elfstab_build_psymtabs.
* gdb-stabs.h (struct dbx_symfile_info): Add stab_section.
(DBX_STAB_SECTION): New macro.
* stabsread.h (elfstab_build_psymtabs): Update prototype.
* symfile.c (symfile_dummy_outputs): New function.
(symfile_relocate_debug_section): New function.
* symfile.h (symfile_relocate_debug_section): Add prototype.
