Deduplicate all netdata strings (#13570)
* rrdfamily
* rrddim
* rrdset plugin and module names
* rrdset units
* rrdset type
* rrdset family
* rrdset title
* rrdset title more
* rrdset context
* rrdcalctemplate context and removal of context hash from rrdset
* strings statistics
* rrdset name
* rearranged members of rrdset
* eliminate rrdset name hash; rrdcalc chart converted to STRING
* rrdset id, eliminated rrdset hash
* rrdcalc, alarm_entry, alert_config and some of rrdcalctemplate
* rrdcalctemplate
* rrdvar
* eval_variable
* rrddimvar and rrdsetvar
* rrdhost hostname, os and tags
* fix master commits
* added thread cache; implemented string_dup without locks
* faster thread cache
* rrdset and rrddim now use dictionaries for indexing
* rrdhost now uses dictionary
* rrdfamily now uses DICTIONARY
* rrdvar using dictionary instead of AVL
* allocate the right size to rrdvar flag members
* rrdhost remaining char * members to STRING *
* better error handling on indexing
* strings now use a read/write lock to allow parallel searches to the index
* removed AVL support from dictionaries; implemented STRING with native Judy calls
* string releases should be negative
* only 31 bits are allowed for enum flags
* proper locking on strings
* string threading unittest and fixes
* fix lgtm finding
* fixed naming
* stream chart/dimension definitions at the beginning of a streaming session
* thread stack variable is undefined on thread cancel
* rrdcontext garbage collect per host on startup
* worker control in garbage collection
* relaxed deletion of rrdmetrics
* type checking on dictfe
* netdata chart to monitor rrdcontext triggers
* Group chart label updates
* rrdcontext better handling of collected rrdsets
* rrdpush incremental transmition of definitions should use as much buffer as possible
* require 1MB per chart
* empty the sender buffer before enabling metrics streaming
* fill up to 50% of buffer
* reset signaling metrics sending
* use the shared variable for status
* use separate host flag for enabling streaming of metrics
* make sure the flag is clear
* add logging for streaming
* add logging for streaming on buffer overflow
* circular_buffer proper sizing
* removed obsolete logs
* do not execute worker jobs if not necessary
* better messages about compression disabling
* proper use of flags and updating rrdset last access time every time the obsoletion flag is flipped
* monitor stream sender used buffer ratio
* Update exporting unit tests
* no need to compare label value with strcmp
* streaming send workers now monitor bandwidth
* workers now use strings
* streaming receiver monitors incoming bandwidth
* parser shift of worker ids
* minor fixes
* Group chart label updates
* Populate context with dimensions that have data
* Fix chart id
* better shift of parser worker ids
* fix for streaming compression
* properly count received bytes
* ensure LZ4 compression ring buffer does not wrap prematurely
* do not stream empty charts; do not process empty instances in rrdcontext
* need_to_send_chart_definition() does not need an rrdset lock any more
* rrdcontext objects are collected, after data have been written to the db
* better logging of RRDCONTEXT transitions
* always set all variables needed by the worker utilization charts
* implemented double linked list for most objects; eliminated alarm indexes from rrdhost; and many more fixes
* lockless strings design - string_dup() and string_freez() are totally lockless when they dont need to touch Judy - only Judy is protected with a read/write lock
* STRING code re-organization for clarity
* thread_cache improvements; double numbers precision on worker threads
* STRING_ENTRY now shadown STRING, so no duplicate definition is required; string_length() renamed to string_strlen() to follow the paradigm of all other functions, STRING internal statistics are now only compiled with NETDATA_INTERNAL_CHECKS
* rrdhost index by hostname now cleans up; aclk queries of archieved hosts do not index hosts
* Add index to speed up database context searches
* Removed last_updated optimization (was also buggy after latest merge with master)
