Incompatible changes

(Interpreter)
	- With WMode = 1, CID-keyed fonts with no Metrics2 now use default
metrics computed from FontBBox rather than the horizontal metrics.
(PDF interpreter)
	- The interpreter now skips to the next EOL after reading the data
following the ID operator.
	- The incorrectly named ViewerOrientation DSC comment is now
corrected to ViewingOrientation.
(Streams)
	- All decoding filters that recognize an EOD in the source data
must now have an init procedure that sets state->min_left = 1.
(Library)
	- The glyph_data, subr_data, and seac_data procedures in a Type 1
font (gs_type1_data_procs), and the glyph_data procedure passed to
psf_{check,get}_outline_glyphs, must now return 1 iff the outline string was
newly allocated and should be freed by the caller, like the get_outline
procedure of Type 42 fonts (gs_type42_data).
	- The ip_state structure is renamed ip_state_t, and has a new
member, free_char_string.
	- The incorrectly named ViewerOrientation DSC comment is now
corrected to ViewingOrientation, and the viewer_orientation members of
the DSC parsing structure are corrected to viewing_orientation.
