/* Archive handling.  ECOFF uses what appears to be a unique type of

   contents are encoded in the name of the armap itself.  At least for
   now, we only support archives with the same byte ordering in the
   armap and the contents.

   The first four bytes in the armap are the number of symbol
   definitions.  This is always a power of two.

   This is followed by the symbol definitions.  Each symbol definition
   occupies 8 bytes.  The first four bytes are the offset from the
   start of the armap strings to the null-terminated string naming
   this symbol.  The second four bytes are the file offset to the
   archive member which defines this symbol.  If the second four bytes
   are 0, then this is not actually a symbol definition, and it should
   be ignored.

   The symbols are hashed into the armap with a closed hashing scheme.
   See the functions below for the details of the algorithm.

   After the symbol definitions comes four bytes holding the size of
   the string table, followed by the string table itself.  */
