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.
This fixes a bug with llvm-ar not being able to read archives produced by
llvm-ranlib when there are members with odd long file name lengths.

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.
