rebase 4.5.0-1

[Corinna Vinschen]

The following packages have been uploaded to the Cygwin distribution:

* rebase-4.5.0-1

This package contains the Cygwin rebase utilities.  Use rebase for
specific DLLs or rebaseall for all DLLs installed by Cygwin's setup.exe.

What's new:

- Introduce --merge-files (-M) flag.

  The --merge-files flag is to update the database for new files, without
  performing a rebase.  The file names provided should have been rebased
  using the --oblivious flag just before.

- Introduce --high-entropy-va (-e) flag.

  This flag allows for setting, clearing, and displaying the value of the
  "high entropy va" dll characteristics flag, which is required to indicate
  that a DLL is 64 bit ASLR clean.

- The --verbose option now prints a reason why rebase is necessary.

- Some errors causing an unnecessary rebase are fixed.

- Add a --with-posix-shell configure flag to use other shells than dash to
  be used as default shell in scripts.  This is only interesting when
  building rebase for non-Cygwin distros.
