RRD structures managed by dictionaries () 
* rrdset - in progress

* rrdset optimal constructor; rrdset conflict

* rrdset final touches

* re-organization of rrdset object members

* prevent use-after-free

* dictionary dfe supports also counting of iterations

* rrddim managed by dictionary

* rrd.h cleanup

* DICTIONARY_ITEM now is referencing actual dictionary items in the code

* removed rrdset linked list

* Revert "removed rrdset linked list"

This reverts commit 690d6a588b4b99619c2c5e10f84e8f868ae6def5.

* removed rrdset linked list

* added comments

* Switch chart uuid to static allocation in rrdset
Remove unused functions

* rrdset_archive() and friends...

* always create rrdfamily

* enable ml_free_dimension

* rrddim_foreach done with dfe

* most custom rrddim loops replaced with rrddim_foreach

* removed accesses to rrddim->dimensions

* removed locks that are no longer needed

* rrdsetvar is now managed by the dictionary

* set rrdset is rrdsetvar, fixes https://github.com/netdata/netdata/pull/13646#issuecomment-1242574853

* conflict callback of rrdsetvar now properly checks if it has to reset the variable

* dictionary registered callbacks accept as first parameter the DICTIONARY_ITEM

* dictionary dfe now uses internal counter to report; avoided excess variables defined with dfe

* dictionary walkthrough callbacks get dictionary acquired items

* dictionary reference counters that can be dupped from zero

* added advanced functions for get and del

* rrdvar managed by dictionaries

* thread safety for rrdsetvar

* faster rrdvar initialization

* rrdvar string lengths should match in all add, del, get functions

* rrdvar internals hidden from the rest of the world

* rrdvar is now acquired throughout netdata

* hide the internal structures of rrdsetvar

* rrdsetvar is now acquired through out netdata

* rrddimvar managed by dictionary; rrddimvar linked list removed; rrddimvar structures hidden from the rest of netdata

* better error handling

* dont create variables if not initialized for health

* dont create variables if not initialized for health again

* rrdfamily is now managed by dictionaries; references of it are acquired dictionary items

* type checking on acquired objects

* rrdcalc renaming of functions

* type checking for rrdfamily_acquired

* rrdcalc managed by dictionaries

* rrdcalc double free fix

* host rrdvars is always needed

* attempt to fix deadlock 1

* attempt to fix deadlock 2

* Remove unused variable

* attempt to fix deadlock 3

* snprintfz

* rrdcalc index in rrdset fix

* Stop storing active charts and computing chart hashes

* Remove store active chart function

* Remove compute chart hash function

* Remove sql_store_chart_hash function

* Remove store_active_dimension function

* dictionary delayed destruction

* formatting and cleanup

* zero dictionary base on rrdsetvar

* added internal error to log delayed destructions of dictionaries

* typo in rrddimvar

* added debugging info to dictionary

* debug info

* fix for rrdcalc keys being empty

* remove forgotten unlock

* remove deadlock

* Switch to metadata version 5 and drop
  chart_hash
  chart_hash_map
  chart_active
  dimension_active
  v_chart_hash

* SQL cosmetic changes

* do not busy wait while destroying a referenced dictionary

* remove deadlock

* code cleanup; re-organization;

* fast cleanup and flushing of dictionaries

* number formatting fixes

* do not delete configured alerts when archiving a chart

* rrddim obsolete linked list management outside dictionaries

* removed duplicate contexts call

* fix crash when rrdfamily is not initialized

* dont keep rrddimvar referenced

* properly cleanup rrdvar

* removed some locks

* Do not attempt to cleanup chart_hash / chart_hash_map

* rrdcalctemplate managed by dictionary

* register callbacks on the right dictionary

* removed some more locks

* rrdcalc secondary index replaced with linked-list; rrdcalc labels updates are now executed by health thread

* when looking up for an alarm look using both chart id and chart name

* host initialization a bit more modular

* init rrdlabels on host update

* preparation for dictionary views

* improved comment

* unused variables without internal checks

* service threads isolation and worker info

* more worker info in service thread

* thread cancelability debugging with internal checks

* strings data races addressed; fixes https://github.com/netdata/netdata/issues/13647

* dictionary modularization

* Remove unused SQL statement definition

* unit-tested thread safety of dictionaries; removed data race conditions on dictionaries and strings; dictionaries now can detect if the caller is holds a write lock and automatically all the calls become their unsafe versions; all direct calls to unsafe version is eliminated

* remove worker_is_idle() from the exit of service functions, because we lose the lock time between loops

* rewritten dictionary to have 2 separate locks, one for indexing and another for traversal

* Update collectors/cgroups.plugin/sys_fs_cgroup.c

Co-authored-by: Vladimir Kobal <vlad@prokk.net>

* Update collectors/cgroups.plugin/sys_fs_cgroup.c

Co-authored-by: Vladimir Kobal <vlad@prokk.net>

* Update collectors/proc.plugin/proc_net_dev.c

Co-authored-by: Vladimir Kobal <vlad@prokk.net>

* fix memory leak in rrdset cache_dir

* minor dictionary changes

* dont use index locks in single threaded

* obsolete dict option

* rrddim options and flags separation; rrdset_done() optimization to keep array of reference pointers to rrddim;

* fix jump on uninitialized value in dictionary; remove double free of cache_dir

* addressed codacy findings

* removed debugging code

* use the private refcount on dictionaries

* make dictionary item desctructors work on dictionary destruction; strictier control on dictionary API; proper cleanup sequence on rrddim;

* more dictionary statistics

* global statistics about dictionary operations, memory, items, callbacks

* dictionary support for views - missing the public API

* removed warning about unused parameter

* chart and context name for cloud

* chart and context name for cloud, again

* dictionary statistics fixed; first implementation of dictionary views - not currently used

* only the master can globally delete an item

* context needs netdata prefix

* fix context and chart it of spins

* fix for host variables when health is not enabled

* run garbage collector on item insert too

* Fix info message; remove extra "using"

* update dict unittest for new placement of garbage collector

* we need RRDHOST->rrdvars for maintaining custom host variables

* Health initialization needs the host->host_uuid

* split STRING to its own files; no code changes other than that

* initialize health unconditionally

* unit tests do not pollute the global scope with their variables

* Skip initialization when creating archived hosts on startup. When a child connects it will initialize properly
