[PATCH v3 00/36] maintainer omnibus: testing, fuzz, plugins, documentation, gdbstub (pre-PR)

[Alex Bennée]

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.

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

The following are still missing review:

 - gdbstub: lightly refactor connection to avoid snprintf
 - docs/devel: introduce some key concepts for QOM development
 - 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
