The installer package will now detect a previous installation and warn the user
that the previous installation will be deleted. If the user continues, the
installer will delete the previous installation and install the package as
usual.
Fixes#4293.

This changes the misc/dist program to generate OS X
packages using pkgbuild and productbuild.
The productbuild utility makes it easy to generate
packages with a custom Distribution file. This allows
us to add an installcheck script that presents a
friendly message to users who are running on an old
version of Mac OS X.
The change also fixes a few issues with the
postinstall script:
- In-repo version of the script has been made
executable. Installers generated using the new
tools couldn't execute it otherwise.
- It now uses -d for checking for the existence
of the Xcode specs directory.
- The call to sudo.bash has been dropped since cov
and prof aren't bundled with the binary
distributions.
Fixes#3455.
Tested on 10.5.8, 10.6.0, 10.6.8 and 10.7.3.
