* Use cargo-batch * Run CI on mac runner * Rely on MSRV and nightly jobs to lint * Build docs separately * Don't copy examples - fix builds on stable * Run everything by default, set CI env var in ci command * Run batched commands with RUSTC_BOOTSTRAP enabled * Force cargo-batch to correctly ignore unstable option * Test with nightly * Use a persistent target folder, remove cache * Don't delete the lp examples * Restore target dir * Build with stable again * Fix rebase fail * Remove handling tests * Remove redundant code * Restore repeated test run option * Add simpler cargo check * Introduce check-packages * Remove stabilized -Zdoctest-xcompile * Clean up commented code * Remove more stuff * Fix uart_uhci test * No badger for us
