Merge remote-tracking branch 'remotes/bonzini-gitlab/tags/for-upstream' into staging

* fix --enable-fuzzing linker failures (Alexander)
* target/i386: Add bus lock debug exception support (Chenyi)
* update documentation for preferred boolean option syntax (Daniel)
* make SCSI io_timeout configurable (Hannes)
* fix handling of guest recoverable SCSI errors (myself)
* misc fixes (Pavel, Zheng Zhan Liang, Zihao)
* fix installation of binaries with entitlements (Akihiko)
