* coffcode.h: Moved ALIGN macro to libbfd.h. Removed i960_align.

	* coffcode.h: Moved ALIGN macro to libbfd.h. Removed i960_align.
	* libbfd.h: Moved ALIGN macro here.
	* bout.c (b_out_callback): Replace i960_align by align_power.

	* libaout.h (struct aoutdata):  Added fields page_size,
	segment_size and exec_bytes_size.  These help generic code
	(in aoutx.h and libaout.h) to figure out where to align
	the various segments in a demand paged file.
	* libaout.h (WRITE_HEADER):  Use new (struct aoutdata) fields
	to decide if the exec header counts in a_text (text segment size).
	Also, assume D_PAGED flag is set; don't set it here.
	* bout.c (b_out_callback): Add initialization of
	adata fields page_size, segment_size, and exec_bytes_size.
	* host-aout.c (NAME(host_aout, callback) and
	NAME(host_aout,mkobject): Ditto.
	* i386aout.c (aout386_callback) and new aout386_mkobject): Ditto.
	* newos3.c (newsos3_callback) and new newsos_mkobject): Ditto.
	* aoutf1.c (sunos4_callback) and new sunos_mkobject): Ditto.
	* aoutx.h (NAME(aout,some_aout_object_p)): Don't subtract
	EXEC_BYTES_SIZE from the a_test size; this is only appropriate
	for some systems (mainly sunos), so do it in the callback instead.
	Same routine: Add stuff to the THIS_IS_ONLY_DOCUMENTATION comment.
	* aoutx.h (NAME(aout,set_section_contents): Change the way
	filepos and size of sections are carried out to support
	older styles of demand paged executables.
