Revamp the build system.

This achieves several goals:

 * Less reliance on scripts so we have better portability to Windows
   (though we still have a ways to go for proper Windows support).
   Luajit, luarocks, moonscript, and busted are all installed via CMake
   now.
 * Trying to make use of pkg-config to get the correct libraries.  The
   latest libuv is still broken in this regard, but we'll at least be in
   a position to use it.
 * Allow the use of Ninja or make.  The former runs faster in many
   environments, and automatically makes use of parallel builds.

This also allows for system installed dependencies--though not through
the Makefile just yet--and adds support for FreeBSD.

This also make us build libuv and luajit as static libraries only, since
we're only concerned about having static libraries for our bundled
dependencies.

-   *    them from sending it twice.
-   *
-   * 2. Write errors are always reported. Write errors are bad because they
-   *    mean data loss: we've read data but now we can't write it out.
-   *
-   * We try to use pread() and fall back to regular read() if the source fd
-   * doesn't support positional reads, for example when it's a pipe fd.
-   *
-   * If we get EAGAIN when writing to the target fd, we poll() on it until
-   * it becomes writable again.
-   *
-   * FIXME: If we get a write error when use_pread==1, it should be safe to
-   *        return the number of sent bytes instead of an error because pread()
-   *        is, in theory, idempotent. However, special files in /dev or /proc
-   *        may support pread() but not necessarily return the same data on
-   *        successive reads.
-   *
-   * FIXME: There is no way now to signal that we managed to send *some* data
-   *        before a write error.
