the tree being fetched from a Subversion repository. The revision
number is now optional (and defaults to HEAD).
This makes `fetchsvn' more pure. First, a URL/revision tuple does
not uniquely identify a file resource, since the repository itself
might change. Second, `svn:external' attributes can cause arbitrary
resources to be exported.
A script `nix-prefetch-svn' has been provided to determine the hash
of a URL.

* Make builders unexecutable by removing the hash-bang line and
execute permission.
* Convert calls to `derivation' to `mkDerivation'.
* Remove `system' and `stdenv' attributes from calls to
`mkDerivation'. These transformations were all done automatically,
so it is quite possible I broke stuff.
* Put the `mkDerivation' function in stdenv/generic.
