[pcf] Massive unsigning (part 1).

Unofficial specifications hesitate to use unsigned 32-bit integers.
Negative values caused a lot of trouble in the past and it is safer
and easier to treat some properties as unsigned.

* src/pcf/pcf.h (PCF_AccelRec): Use unsigned values for `fontAscent',
`fontDescent', and `maxOverlap'.
* src/pcf/pcfread.c (pcf_load_font, pcf_get_accel): Updated.
* src/pcf/pcfdrivr.c (PCF_Glyph_Load, PCF_Size_Select,
PCF_Size_Request): Updated.
