Revert "curl: Update to version 7.29.0."

This reverts commit fd2cff94796fdc7b9a2f816403de2496cf76d0d7.

nix's substituter fails with this curl, so revert it until that's fixed.

types.nix: Add a ‘lines’ type

This is like types.string, but values are merged by putting a newline
in between them.  This is mostly useful for configuration file
options, where we don't want values accidentally ending up on the same
line.

Note that almost all options with string type in NixOS should either
be unmergable (i.e. should be marked with ‘types.uniq’) or should
actually be of type ‘lines’.  So it might make sense to remove the
merge function for the ‘string’ type eventually.
linux: Update to 3.2.38
all-packages.nix: provide a variant of Darcs that includes the executable, but not the library

The reduced 'darcs' derivation is supposed to be run-time independent of the
Haskell compiler. Unfortunately, this isn't quite true yet because the HTTP
package bakes its own store path into the library. This causes Darcs -- which
links the HTTP library statically -- to depend on 'HTTP', which in turn depends
on lot of other Haskell stuff. Patching HTTP to get rid of that reference looks
feasible, though.
