- drop nss-linux3.patch, builds out of the box on Linux 3.x now
- drop nss-string-concat.patch, was fixed upstream
- drop nss-clang_os_Linux_x86_s_comments.patch
       nss-clang_os_Linux_x86_64_s_comments.patch
  the invalid asm comments were fixed upstream:
  https://bugzilla.mozilla.org/show_bug.cgi?id=624868
- drop nss-asm-fix.patch, fixed upstream:
  https://bugzilla.mozilla.org/show_bug.cgi?id=671711
- not updated nss.patch.mingw since it looks unmaintained
- remove the setting of FREEBL_NO_DEPEND, which is
  a) no longer necessary, because it will be set automatically
     on Linux 2.6
  b) harmful because it prevents automatic setting of FREEBL_LOWHASH,
     which is necessary to prevent conflicts with system libfreebl3.so
     at least on Fedora 16/17
