track memory footprint of Netdata (#14294)

* track memory footprint of Netdata

* track db modes alloc/ram/save/map

* track system info; track sender and receiver

* fixes

* more fixes

* track workers memory, onewayalloc memory; unify judyhs size estimation

* track replication structures and buffers

* Properly clear host RRDHOST_FLAG_METADATA_UPDATE flag

* flush the replication buffer every 1000 times the circular buffer is found empty

* dont take timestamp too frequently in sender loop

* sender buffers are not used by the same thread as the sender, so they were never recreated - fixed it

* free sender thread buffer on replication threads when replication is idle

* use the last sender flag as a timestamp of the last buffer recreation

* free cbuffer before reconnecting

* recreate cbuffer on every flush

* timings for journal v2 loading

* inlining of metric and cache functions

* aral likely/unlikely

* free left-over thread buffers

* fix NULL pointer dereference in replication

* free sender thread buffer on sender thread too

* mark ctx as used before flushing

* better logging on ctx datafiles closing
