Remove lots of dated configuration from this repo

Lots of data build stuff is still here from awhile ago when this repo was
producing Cargo binaries, but the rust-lang/rust repo is now responsible for all
these binaries and build configurations. We no longer need to produce artifacts
or have tons of cross-compiles as rust-lang/rust does all that work, instead
let's just test the likely-to-regress platforms and have rust-lang/rust take
care of the rest.

This commit:

* Deletes the old `configure` script and `Makefile`
* Rewrites `src/doc` management as a shell script
* Trims down Travis/AppVeyor configuration
