Subject: package.el: Safer package upgrade

[Message part 1 (text/plain, inline)]

The current `package-upgrade' from package.el delete old package
before installing the new one. This can be problematic if the user
interrupt the process or if there is some network problems.

Since `package-install' allow the same package to be installed if the
argument is of `package-desc' type. We can use this to make package
upgrade atomic by deferring `package-delete'.
