* Fix a couple of misc errors in build scripts. * Tweak scripts/kconfigs to make bpftrace work. * Update how CI caching works to make builds faster (6 minute turnaround time) * Update CI config to generate per-scheduler debug archives w/ guest dmesg/scheduler stdout, guest stdout, bpftrace script output, veristat output. * Update build scripts to accept the following: ** VNG RW -- write to host filesystem (better caching, logging). * For stress tests in particular (via ini config): ** QEMU Opts -- to facilitate reproducing bugs (i.e. high core count). ** bpftrace scripts -- specify bpftrace scripts to run during stress tests.
