Merge branch 'rickard/port-optimizations/OTP-10336' into rickard/r16/port-optimizations/OTP-10336
* rickard/port-optimizations/OTP-10336: Change annotate level for emacs-22 in cerl Update etp-commands Add documentation on communication in Erlang Add support for busy port message queue Add driver callback epilogue Implement true asynchronous signaling between processes and ports Add erl_drv_[send|output]_term Move busy port flag Use rwlock for driver list Optimize management of port tasks Improve configuration of process and port tables Remove R9 compatibility features Use ptab functionality also for ports Prepare for use of ptab functionality also for ports Atomic port state Generalize process table implementation Implement functionality for delaying thread progress from unmanaged threads Conflicts: erts/doc/src/erl_driver.xml erts/doc/src/erlang.xml erts/emulator/beam/beam_bif_load.c erts/emulator/beam/beam_bp.c erts/emulator/beam/beam_emu.c erts/emulator/beam/bif.c erts/emulator/beam/copy.c erts/emulator/beam/erl_alloc.c erts/emulator/beam/erl_alloc.types erts/emulator/beam/erl_bif_info.c erts/emulator/beam/erl_bif_port.c erts/emulator/beam/erl_bif_trace.c erts/emulator/beam/erl_init.c erts/emulator/beam/erl_message.c erts/emulator/beam/erl_port_task.c erts/emulator/beam/erl_process.c erts/emulator/beam/erl_process.h erts/emulator/beam/erl_process_lock.c erts/emulator/beam/erl_trace.c erts/emulator/beam/export.h erts/emulator/beam/global.h erts/emulator/beam/io.c erts/emulator/sys/unix/sys.c erts/emulator/sys/vxworks/sys.c erts/emulator/test/port_SUITE.erl erts/etc/unix/cerl.src erts/preloaded/ebin/erlang.beam erts/preloaded/ebin/prim_inet.beam erts/preloaded/src/prim_inet.erl lib/hipe/cerl/erl_bif_types.erl lib/kernel/doc/src/inet.xml lib/kernel/src/inet.erl
