Commit message: Fix for #4084 Use-after-free (heap) in the SFD_GetFontMetaData() function
Fix for #4086 NULL pointer dereference in the SFDGetSpiros() function
Fix for #4088 NULL pointer dereference in the SFD_AssignLookups() function
Add empty sf->fontname string if it isn't set, fixing #4089 #4090 and many
  other potential issues (many downstream calls to strlen() on the value).
CVE: CVE-2020-5395
CWE: CWE-416
