* bfd-in.h (STRING_AND_COMMA): New macro. Takes one constant string as its

  argument and emits the string followed by a comma and then the length of
  the string.
  (CONST_STRNEQ): New macro.  Checks to see if a variable string has a constant
  string as its initial characters.
  (CONST_STRNCPY): New macro.  Copies a constant string to the start of a
  variable string.
* bfd-in2.h: Regenerate.
* <remainign files>: Make use of the new macros.
