[MinGW-dvlpr] Sync pseudo-reloc.c, round #2

[Charles W. <cwi...@us...>]

After the previous synchronization between cygwin and mingw, I took the
result back to the mingw64 guys:
https://sourceforge.net/tracker/?func=detail&atid=983355&aid=2885246&group_id=202880

Merging with them required a few additional changes, so now I'm bring
that result back to mingw (and cygwin). There are some functional
changes in this release -- derived from "upstream" mingw64. To wit:

(a) more uniform handling of errors
(b) no more need for assert() nor assert.h
(c) *all* errors now result in an error message, and abort() [on mingw32
and mingw64]. This is the correct behavior IMO, and obviously the
mingw64 guys feel that way too.

Tested on mingw32 and cygwin.

        Sync pseudo-reloc.c with mingw64
	* psuedo-reloc.c: Remove unnecessary includes.
	Forward declare _pei386_runtime_relocator.
	Decorate _image_base__ symbol with macro for
	mingw64 compatibility. Whitespace changes.
	(__print_reloc_error): Renamed to...
	(__report_error): This. "Returns" void, and
	always aborts. Now used on all platforms.
	(__write_memory): Remove special case error handling
	for different platforms - always call __report_error.
	(do_pseudo_reloc): Remove special case error handling
	for different platforms - always call __report_error.
	(_pei386_runtime_relocator): Decorate _image_base__
	symbol with mingw64 compatibility macro.

OK to commit?
