  Log:
  This patch adds a new ktrace(2) record type, KTR_STRUCT, whose payload
  consists of the null-terminated name and the contents of any structure
  you wish to record.  A new ktrstruct() function constructs and emits a
  KTR_STRUCT record.  It is accompanied by convenience macros for struct
  stat and struct sockaddr.
  
  In kdump(1), KTR_STRUCT records are handled by a dispatcher function
  that runs stringent sanity checks on its contents before handing it
  over to individual decoding funtions for each type of structure.
  Currently supported structures are struct stat and struct sockaddr for
  the AF_INET, AF_INET6 and AF_UNIX families; support for AF_APPLETALK
  and AF_IPX is present but disabled, as I am unable to test it properly.
  
  Since 's' was already taken, the letter 't' is used by ktrace(1) to
  enable KTR_STRUCT trace points, and in kdump(1) to enable their
  decoding.
