Correct the computation of when to add the padding. It is not based on the

member's size. It is based on the oddness/evenness of the file pointer.

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.
