+ Fix the mechanism for upgrading emulator.</p>
+ <p>
+ The appup files for kernel, stdlib and sasl do now
+ recognize two major releases back and include a
+ 'restart_new_emulator' instruction. </p>
+ <p>
+ Appup files can include regular expressions for matching
+ earlier releases.</p>
+ <p>
+ The mechanism for upgrading the emulator is changed so
+ 'restart_new_emulator' will be the first instruction
+ executed. The rest of the upgrade instruction will be
+ executed after the emulator restart.</p>
+ <p>
+ A new upgrade instruction 'restart_emulator' is added for
+ the case where the emulator shall be restarted after all
+ other upgrade instructions.</p>

+ Add release_handler:which_releases/1</p>
+ <p>
+ This is an extension to which_releases that allows a user
+ to specify the status of the releases they wish to be
+ returned. For instance it allows for quickly determining
+ which release is 'permanent' without the need of parsing
+ the entire release list. (Thanks to Joe Williams)</p>

+ <p>
+ Add copy of rel file in releases/Vsn in release tar file</p>
+ <p>
+ systool:make_tar stores the rel file in the releases
+ directory. When unpacking with
+ release_handler:unpack_release, the file is automatically
+ moved to releases/Vsn/. If, however, the tar file is
+ unpacked manually, the rel file might not be moved, and
+ the next release unpacked might overwrite the rel file.
+ To overcome this, systools:make_tar now stores a copy of
+ the rel file in releases/Vsn/ directly and it is not
+ longer necessary to move the file after unpacking.</p>
+ <p>
+ The reason for keeping the file in the releases directory
+ also is that is needs to be extracted separately before
+ the release version (Vsn) is known.</p>
