Without this:
error: failed to select a version for `serde_test_suite`.
... required by package `serde_test_suite-tests v0.0.0`
versions that meet the requirements `= 0.0.0` are: 0.0.0
the package `serde_test_suite-tests` depends on `serde_test_suite`, with features: `serde` but `serde_test_suite` does not have these features.
failed to select a version for `serde_test_suite` which could resolve this conflict
Seems like a Cargo bug -- I will minimize and report.
* move to cargo clippy instead of using the clippy plugin
fixes#729
* non-exectable scripts must be run with `sh`
* don't build serde in the clippy travis job
* only run clippy tests if installing clippy succeeds
* why is travis so picky?
* no more serde_codegen
* serde_test_suite_deps has no features
* don't use empty loops, llvm optimizes them to undefined behaviour
* abort the clippy job when clippy lints are triggered
* use caches on travis to speed up builds
* why are we even using `travis-cargo`?
* need to reinstall clippy frequently due to nightly updates
* command line tools are hard
