Subject: Synchronize blead with changes from ExtUtils::Install 1.46

Apply patches from Michael Schwern (rt #33688, rt #31429, rt #31248)
and from Slaven Rezic (rt #33290).  Also implemented the suggestion from
Schwern about not dieing when failing to remove a shadow file that is
later on in INC than the installed version. (rt #2928)
