	The following changes are mainly to fix bugs of

	one only when the whole source text is consumed.
	(decode_coding_string): Handle the case that the output buffer is
	too small to decode the whole source text.  Use
	allocate_conversion_buffer, extend_conversion_buffer and
	free_conversion_buffer, not get_conversion_buffer.

	* xterm.c (x_append_glyph, x_append_composite_glyph)
	(x_produce_image_glyph, x_append_stretch_glyph): Accomodate to
	changes in struct glyph starting 1999-12-27.  Some bit-fields of
	struct glyph were not set, which made glyphs unequal when compared
	with GLYPH_EQUAL_P.  Redisplay outputs such glyphs, and flickering
	effects were the result.  This also depended on the contents of
	memory returned by xmalloc.  If flickering happens again, activate
	the code in clear_glyph_row that's in #if 0.  If the flickering is
	gone with that, chances are that it is caused by something
	similar.

	* dispnew.c (clear_glyph_row): Add debug code in #if 0.
