We need them to compare against, so that we can decide if we want to
write new files or keep the old ones untouched.

Initial support for parallel 'ghc --make'

Now the log contains the output of all install phases ('setup
configure/build/.../install') instead of only the last ('setup install' if the
build was succcesful).

We do this for 'install -j' already.

Installed packageids

Make the default case the first one, for readability. Tweak versions a little
bit.

'cabal configure': honor the '--constraint' flag.

Fixes #1150. Fixes #1564.

Fixes #1483.

Since we now have a new version-dependent feature: the new --dependency
configure flag.

We generate both --constraint and --dependency flags, but we only need
to pass one or the other, depending on the Cabal version.

that the exact packages are installed rather than letting cabal choose
for itself (potentially choosing the package with the incorrect
hash). Closes: https://github.com/haskell/cabal/issues/1460.

The goal is to learn the installed package id of the package we just
installed, as necessary for #1860. We achieve this by inserting an
additional call to "setup register" that produces the installed package
information in a file. We read and parse that file and could now return
the installed package id, but it is not clear what interface would be
appropriate.

Use a map from package name rather than from constraint, for the
info on the specific packages to use.
