Fixed. Reading the package DB is several times quicker for me now.

* Change the representation of the package database
- the package DB is a directory containing one file per package
instance (#723)
- there is a binary cache of the database (#593, #2089)
- the binary package is now a boot package
- there is a new package, bin-package-db, containing the Binary
instance of InstalledPackageInfo for the binary cache.
Also included in this patch
- Use colour in 'ghc-pkg list' to indicate broken or hidden packages
Broken packages are red, hidden packages are
Colour support comes from the terminfo package, and is only used when
- not --simple-output
- stdout is a TTY
- the terminal type has colour capability
- Fix the bug that 'ghc-pkg list --user' shows everything as broken
