maintainer omnibus: testing, fuzz, plugins, documentation, gdbstub (pre-PR) As softfreeze is fast approaching I thought it would be work combining my various trees into an omnibus series to ease the review and merging. The testing updates exposed a number of latent leaks that confused the oss-fuzz jobs (hence the test-fuzz addition to help debug that). This also includes some minor plugin updates and finally some documentation updates that clean-up and expose the QOM and QDEV APIs which are so core to emulating anything in QEMU. I was intending to roll the PR from the last post but as there is still un-reviewed stuff and some changes I'd missed from previous reviews so I though it was worth one last posting. I'll roll on Monday. v2 - applied a bunch of review tags - added missing doc suggestions from Paolo - tweaked the plugin fix for CI v3 - few more tags - checkpatch cleanups - rolled in gdbstub/next v4 - added #ifdef CONFIG_TCG to the arm_casq_ptw - fixed plugin memory instrumentation with new helper for mmu access - added Thomas' test_arm_bpim2u_gmac tweak - moved pkgs from riscv64-cross patch to earlier qemu-minimal patch The following are still missing review: - gdbstub: lightly refactor connection to avoid snprintf - tests/docker: convert riscv64-cross to lcitool - tests/lcitool: introduce qemu-minimal - tests/lcitool: add an explicit gcc-native package (1 acks, 1 sobs, 0 tbs) - tests/lcitool: update to latest version (1 acks, 1 sobs, 0 tbs) - tests/qtests: clean-up and fix leak in generic_fuzz
