Remove unused arguments for unexec.

The third one is never used, and the last two are always passed as zero.
* src/emacs.c (unexec): Add declaration.
(Fdump_emacs): Only pass the first two arguments to unexec.
Simplify #ifdef.
* src/unexw32.c (unexec):
* src/unexsol.c (unexec):
* src/unexhp9k800.c (unexec):
* src/unexcw.c (unexec): Remove the last 3 arguments, unused.
* src/unexelf.c (unexec): Remove the last 3 arguments, unused.
(find_section): Use const.
* src/unexmacosx.c (unexec): Remove the last 3 arguments, unused.
(unexec_error): Declare it NO_RETURN.
* src/unexcoff.c (make_hdr): Assume bss_start is always zero, remove
it as an argument, remove data_start and entry_address arguments, unused.
(unexec): Remove bss_start, data_start and
entry_address arguments.
* src/unexaix.c (make_hdr): Assume bss_start is always zero, remove
it as an argument, remove data_start and entry_address arguments, unused.
(unexec): Remove bss_start, data_start and
entry_address arguments.

  * Modified heavily since then.

  * Synopsis:
- *	unexec (new_name, old_name, data_start, bss_start, entry_address)
- *	char *new_name, *old_name;
- *	unsigned data_start, bss_start, entry_address;
+ *	unexec (const char *new_name, const char *old_name);
  *
  * Takes a snapshot of the program and makes an a.out format file in the
  * file named by the string argument new_name.
  * If old_name is non-NULL, the symbol table will be taken from the given file.
  * On some machines, an existing old_name file is required.
  *
- * The boundaries within the a.out file may be adjusted with the data_start
- * and bss_start arguments.  Either or both may be given as 0 for defaults.
- *
- * Data_start gives the boundary between the text segment and the data
- * segment of the program.  The text segment can contain shared, read-only
- * program code and literal data, while the data segment is always unshared
- * and unprotected.  Data_start gives the lowest unprotected address.
- * The value you specify may be rounded down to a suitable boundary
- * as required by the machine you are using.
- *
- * Bss_start indicates how much of the data segment is to be saved in the
- * a.out file and restored when the program is executed.  It gives the lowest
- * unsaved address, and is rounded up to a page boundary.  The default when 0
- * is given assumes that the entire data segment is to be stored, including
- * the previous data and bss as well as any additional storage allocated with
- * break (2).
- *
- * The new file is set up to start at entry_address.
- *
