Add the full call chain for host control operations from the Go API
server through the C library to the controller:
- schema/controller.capnp: HostControl struct + hostctrlmsg @21
in Request.body union
- include/typemap.h: xce_hostctrl_t* hostctrlmsg in body union
(placed after @20 clrpreasonmsg, matching capnp ordinal)
- include/client.h, xceapi.h, request.h: declarations for
xcecli_hostctrl, xce_hostctrl, xce_hostctrl_req
- lib/client.c: xcecli_hostctrl (validate + delegate to xce_hostctrl)
- lib/xceapi.c: xce_hostctrl (validate ctx state + send + wait reply)
- lib/request.c: xce_hostctrl_req (validate hostname/empty/nil,
accept only HOST_OPEN/HOST_CLOSE, reject HOST_TAG/UNTAG)
- lib/helper.c: Request_body_hostctrlmsg cases in
xce_request_body() and xce_request_msg_name()
- controller/cluster.c: OPCode_hostcontrol dispatch
- controller/include/cluster.h: do_hostcontrol_op declaration
- controller/worker.c: do_hostcontrol_op + fix pre-existing
goto-clean bug in worker_ctrl that leaked write lock and
reference on HOST_OPEN/HOST_CLOSE no-op paths
TDD: 8 xce_hostctrl_req validation tests (null ep, null ctrl,
null/empty hostname, HOST_DO_NONE no-op, HOST_TAG/UNTAG reject,
negative action reject, HOST_OPEN/CLOSE accept via xce_request).
116/116 xcelib tests pass. CGO_ENABLED=0 Go backend tests pass.

Start from existing entry and apply this-source's fields, rather than
starting from incoming and restoring the other-source's fields. The new
pattern makes it immediately clear which fields each push type WRITES,
without having to reason about which fields are being "restored".
OnHostUpdated keeps the merged := *incoming + if ok guard because the
worker push also populates HostModel/HostType from attrs; config-sourced
values must only win when a prior config push has already set them.
All 37 backend unit tests pass.
Wires the remaining cluster_config_t data into the notification pipeline:
- dispatchConfigPush() extracted as a pure-Go helper (CGO-free, testable)
that drives OnQueueUpdated, OnResourceUpdated, OnHostConfigUpdated, and
OnClusterUpdated from a single config push event
- handleConfigPush() delegates to dispatchConfigPush via the new helper,
eliminating the previous inline loops
- OnHostConfigUpdated and OnClusterUpdated added to NotificationHandler
interface and implemented with partial-merge semantics in DefaultHandler
- rawHostConfigData/rawHostConfigToModel and rawClusterData/rawClusterToModel
added to convert_pure.go with their CGO extraction counterparts in convert.go
Safety fixes from code review:
- OnHostUpdated, OnHostConfigUpdated, OnClusterUpdated now copy *incoming to
a local merged value before mutation, closing the TOCTOU window between
store.Get and store.Put under concurrent pushes
- cClusterConfQueues and cClusterConfResources gain nil-pointer guards
matching the existing guard in cClusterConfHostConfigs
- handleConfigPush gains an explicit gHandler nil check
- cClusterConfToClusterInfo returns nil on empty clustername (prevents phantom
empty-key write to store.Clusters); handleConfigPush logs a warning when nil
- 36 unit tests passing (CGO_ENABLED=0)
- Fix issue to xce_get() api cause client side crash
- add parse resreq section
- add rusage parser
- parse resreq with basic support alternative & compound, still miss select
