* Verify having correct updaters.
* Remove `grow_global_histmaker`
This updater is the same as `grow_histmaker`. The former is not in our
document so we just remove it.

* log allreduce/broadcast caller, engine should track caller stack for
investigation
* tracker support binary config format
* Revert "tracker support binary config format"
This reverts commit 2a28e5e2b55c200cb621af8d19f17ab1bc62503b.
* remove caller, prototype fetch allreduce/broadcast results from resbuf
* store cached allreduce/broadcast seq_no to tracker
* allow restore all caches from other nodes
* try new rabit collective cache, todo: recv_link seems down
* link up cache restore with main recovery
* cleanup load cache state
* update cache api
* pass test.mk
* have a working tests
* try to unify check into actionsummary
* more logging to debug distributed hist three method issue
* update rabit interface to support caller signature matching
* splite seq_counter from cur_cache_seq to different variables
* still see issue with inf loop
* support debug print caller as well as allreduce op
* cleanup
* remove get/set cache from model_recover, adding recover in
loadcheckpoint
* clarify rabit cache strategy, cache is set only by successful collective
call involving all nodes with unique cache key. if all nodes call
getcache at same time, we keep rabit run collective call. If some nodes
call getcache while others not, we backfill cache from those nodes with
most entries
* revert caller logs
* fix lint error
* fix engine mpi signature
* support getcache by ref
* allow result buffer presiet to filestream
* add loging
* try fix checkpoint failure recovery case
* use int64_t to avoid overflow caused seq fault
* try avoid int overflow
* try fix checkpoint failure recovery case
* try avoid seqno overflow to negative by offseting specifial flag value
adding cache seq no to checkpoint/load checkpoint/check point ack to avoid
confusion from cache recovery
* fix cache seq assert error
* remove loging, handle edge case
* add extensive log to checkpoint state with different seq no
* fix lint errors
* clean up comments before merge back to master
* add logs to allreduce/broadcast/checkpoint
* use unsinged int 32 and give seq no larger range
* address remove allreduce dropseq code segment
* using caller signature to filter bootstrapallreduces
* remove get/set cache from empty
* apply signature to reducer
* apply signature to broadcast
* add key to broadcat log
* fix broadcast signature
* fix default _line value for non linux system

* fix doc
* fix engine_empty api
* logging, adding more logs, restore immutable assertion
* print unsinged int with ud
* fix lint
* rename seqtype to kSeq and KCache indicating it's usage
apply kDiffSeq check to load_cache routine
* comment allreduce/broadcast log
* allow tests run on arm
* enable flag to turn on / off cache
* add log info alert if user choose to enable rabit bootstrap cache
* add rabit_debug setting so user can use config to turn on
* log flags when user turn on rabit_debug
* force rabit restart if tracker assign -1 rank
* use OPENMP to vecotrize reducer
* address comment
* Revert "address comment"
