  Add many checks to protect against malformed PCF files.
  
  * src/pcf/pcfdrivr.c (PCF_Face_Done): Protect against NULL pointers.
  (PCF_Face_Init): Add calls to PCF_Face_Done in case of errors.
  
  * src/pcf/pcfread.c (pcf_read_TOC): Protect against malformed table
  data and check that tables don't overlap (using a simple
  bubblesort).
  (PCF_METRIC_SIZE, PCF_COMPRESSED_METRIC_SIZE, PCF_PROPERTY_SIZE):
  New macros which give the size of data structures in the data
  stream.
  (pcf_get_properties): Use rough estimates to get array size limits.
  Assign `face->nprops' and `face->properties' earlier so that a call
  to PCF_Face_Done can do the clean-up in case of error.
  Protect against invalid string offsets.
  (pcf_get_metrics): Clean up code.
  Adjust tracing message levels.
  Use rough estimate to get array size limit.
  (pcf_get_bitmaps): Clean up code.
  Adjust tracing message levels.
  Use rough estimates to get offset limits.
  (pcf_get_encodings): Adjust tracing message level.
  (pcf_get_accel): Clean up code.
