`verbose'; print diagnostic messages only if it is non-zero. All
callers changed to pass a zero value unless DEBUG_DUMP is defined
in the environment.

static "bss" section is used for heap space during preload, and
bss data is now written to the proper section area when dumping.
(need_to_recreate_heap): Renamed to using_dynamic_heap.
(heap_index_in_executable): Obsolete variable removed.
(data_section): New variable.
(data_start_va): Renamed to data_start.
(data_start_file): Obsolete variable removed.
(bss_section):
(extra_bss_size):
(bss_section_static):
(bss_start_static):
(bss_size_static):
(extra_bss_size_static):
(heap_section): New variables.
(_start): Remove code based on old unexec method. Call init_heap
to initialize sbrk heap.
(close_file_data): Update size of file when closing, so that
unexec doesn't have to work out exact size in advance.
(get_bss_info_from_map_file):
(get_section_size): Obsolete functions removed.
(rva_to_section): Fix minor bug, and add a work-around for a bug
in very old linkers.
(offset_to_section):
(relocate_offset): New functions.
(OFFSET_TO_RVA):
(RVA_TO_OFFSET):
(RVA_TO_SECTION_OFFSET):
(PTR_TO_RVA):
(PTR_TO_OFFSET):
(OFFSET_TO_PTR): New macros.
(get_section_info): Modify to support new unexec method;
determines address ranges in process that need dumping, and COFF
sections where data will be dumped. Allows for static and global
bss data to be in separate ranges. No longer relies on knowledge
of section names.
(copy_executable_and_dump_data_section): Renamed
copy_executable_and_dump_data. Completely rewritten to copy
executable section by section, so that raw data areas can be
expanded to hold dumped data as necessary. Allows for bss data to
be in same section as initialized data. Reduces size of static
heap section to that used during preload.
(dump_bss_and_heap):
(w32_fatal_reload_error):
(read_in_bss):
(map_in_heap): Obsolete functions removed.
(unexec): Rounds off preload heap to nearest page rather than
virtual allocation unit. Modified to match other changes.

(get_bss_info_from_map_file): Only define if SEPARATE_BSS_SECTION.
(get_section_info): Use my_begbss_static, my_endbss_static to
determine bounds of bss.
(w32_fatal_reload_error): New function.
(read_in_bss, map_in_heap): Invoke w32_fatal_reload_error upon error.

Declare extern data and functions.
(file_data): Move definition from w32heap.c.
(_start): Add debug hook for when profiling.
Spoof executable name when using profilers.
Invoke sbrk immediately when undumped.
(unexec): Print error messages when input and output dump files
cannot be opened.
Reset header checksum.
(open_input_file, open_output_file): Return status instead of aborting.
(get_section_size): Handle different linkers.
(find_section, rva_to_section): New functions.
(get_section_info) [SEPARATE_BSS_SECTION]: Make code for using
a separate .bss section conditional.
Use my_begbss and my_endbss to determine .bss size by default.
Look for Emacs data in EMDATA section.

executable, search the symbol map file for them.
