Better tracing of loaded glyphs. 

Previously, the loading of a glyph was traced at level 4, if at all.
With this change, all font loading routines emit a tracing message
at level 1, making it easier to select tracing output (for example
using F2_DEBUG="any:1 afhints:7 aflatin:7").

* src/bdf/bdfdrivr.c (BDF_Glyph_Load): Add tracing message.
* src/cff/cffdrivr.c (cff_glyph_load): Ditto.
* src/cff/cffgload.c (cff_decoder_prepare): Improve tracing
messages.
* src/cid/cidgload.c (cid_load_glyph): Use level 1 for tracing
message.
* src/pcf/pcfdrivr.c (PCF_Glyph_Load): Ditto.
* src/pfr/pfrobjs.c (pfr_slot_load): Add tracing message.
* src/truetype/ttgload.c (TT_Load_Glyph): Ditto.
* src/type1/t1gload.c (T1_Load_Glyph): Ditto.
* src/type42/t42objs.c (T42_GlyphSlot_Load): Ditto.
* src/winfonts/winfnt.c (FNT_Load_Glyph): Ditto.
