UPX v3.05,Changelog
* i386-linux and amd64-linux support shared libraries (DT_INIT must exist, all info needed by runtime loader must be first in .text, etc.)
* Linux /proc/self/exe now is preserved by default, by leaving behind one page. New compress-time option --unmap-all-pages is available.
* Withdraw support for shared libraries on Darwin (Apple Mac OS X) because upx does not understand enough about .dylib.
* bug fixes
