* dwarf2read.c (dwarf_info_section, dwarf_abbrev_section)
(dwarf_line_section, dwarf_pubnames_section, dwarf_aranges_section)
(dwarf_loc_section, dwarf_macinfo_section, dwarf_str_section)
(dwarf_ranges_section, dwarf_frame_section)
(dwarf_eh_frame_section): Removed.
(dwarf2_resize_section): Likewise.
(dwarf2_read_section): Now static, use bfd_mmap() if possible.
(dwarf2_get_section_info): New function.
(munmap_section_buffer): Likewise.
(dwarf2_per_objfile_cleanup): Likewise.
(section_is_p): Signature change.
* dwarf2-frame.c (dwarf2_build_frame_info): Use
dwarf2_get_section_info instead of dwarf2_read_section.
