UPX for Linux 3.09

Changes in 3.09 (18 Feb 2013):
* New option --preserve-build-id for GNU ELF.
* Allow for code signing and LC_UUID on Mac OS X executables.
* Allow non-contiguous LC_SEGMENTs and 0==.vmsize for Mach-O.
* Allow zero-filled final page in PackUnix::canUnpack().
* bug fixes

Changes in 3.08 (12 Dec 2011):
* Fix allocation in runtime stub for darwin.macho-entry (i386 and amd64).
* Compress shared library on ELF i386 only [ld.so threatens even this case].
* Attempt to support ELF on QNX 6.3.0 for armel (experimental).
* Better diagnostic when ELF -fPIC is needed.
* PT_NOTE improvements for *BSD.
* Preserve more ELF .e_flags on ARM.
* Minor code improvements for ELF stubs.
* Defend against another flavor of corrupt PE header.
* bug fixes

Changes in 3.07 (08 Sep 2010):
* win32/pe: fixed relocation handling for files with *no* TLS callbacks
[severe bug introduced in 3.06]

Changes in 3.06 (04 Sep 2010):
* win32/pe: TLS callback support contributed by Stefan Widmann. Thanks!
* bug fixes

Changes in 3.05 (27 Apr 2010):
* 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

Changes in 3.04 (27 Sep 2009):
* new format Mach/AMD64 supports 64-bit programs on Apple Macintosh.
* new formats Dylib/i386 and Dylib/ppc32 support shared libraries
[such as browser plugins] on Darwin (Apple Macintosh). An existing
-init function (LC_ROUTINES command) is required.
* new format vmlinuz/armel for Debian NSLU2 (etc.) linux kernel
* bvmlinuz boot protocol 2.08 for 386 Linux kernel
* Extended ABI version 4 for armel-eabi ARM Linux ELF
* bug fixes

Changes in 3.03 (27 Apr 2008):
* implement cache flushing for PowerPC (esp. model 440)
* fix cache flushing on MIPS (>3 MiB compressed, or with holes)
* fix MIPS big-endian
* bug fixes

Changes in 3.02 (16 Dec 2007):
* fix unmapping on arm-linux.elf
* fix error checking in mmap for i386-linux.elf [triggered by -fPIE]
* bug fixes

Changes in 3.01 (31 Jul 2007):
* new options --no-mode, --no-owner and --no-time to disable preservation
of mode (file permissions), file ownership and timestamps.
* dos/exe: fixed an incorrect error message caused by a bug in
relocation handling
* new format linux/mipsel supports ELF on [32-bit] R3000
* fix argv[0] on PowerPC with --lzma
* bug fixes
