Revision 543638

Normalize libapriconv-1 for mingw as well as generic-nix:

  * name the shlib libapriconv-1
  * on mingw builds, add win32 objects
  * write the headers to include/apr-1 for aprutil xlate to find
  * name the resulting utility bin/apriconv instead of iconv to avoid
    clobbering system-installed utilities. 

Requires the 1.2.0 designation (already committed)
