a98ccac6fc Fix some things for Mac OSX archives: 
* ensure trailing spaces are eliminated so they don't factor into the
  length of a member's name.
* make sure all the bytes of a name are written even if the name ends in
  multiple null characters (bug in OSX ar)
* make sure we provide the full member name when searching for symbols so
  the module name is not accidentally duplicated.

3e245bd4d5 Make sure we parse bytecode with a module identifier that reflects the full 
name of the module: "Archive.a(object.o)"

f59013e0fa Despite documentation to the contrary, Mac OSX and BSD 4.4 archive formats 
*do* include the length of the long file in the length of the member and
they are *not* null terminated.

2d66bbb7c3 Per code review:\ 
* Make the numVbrBytes function more efficient and better documented \
* Fix a bug in name truncation \
* Add comments before functions \
* Get rid of functions that are now inlined into the header \
* Do not have Archive doing symbol table printing \
* Put assert comments into the assert so they print out \

10b5a5c0da Do not emit FunctionBlock blocks for external functions. This shrinks 
bytecode files by about 8 bytes per external function

571b490404 If a function is external, do not output a FunctionBlock for the function 
AT ALL.  This saves 11 bytes per external function from the bytecode file,
and is also required to make GhostLinkage work.

52da956231 * Make sure the string table gets read even if there isn't a foreign 
symbol table.

  symbol table.
