New logging layer () 
* cleanup of logging - wip

* first working iteration

* add errno annotator

* replace old logging functions with netdata_logger()

* cleanup

* update error_limit

* fix remanining error_limit references

* work on fatal()

* started working on structured logs

* full cleanup

* default logging to files; fix all plugins initialization

* fix formatting of numbers

* cleanup and reorg

* fix coverity issues

* cleanup obsolete code

* fix formatting of numbers

* fix log rotation

* fix for older systems

* add detection of systemd journal via stderr

* finished on access.log

* remove left-over transport

* do not add empty fields to the logs

* journal get compact uuids; X-Transaction-ID header is added in web responses

* allow compiling on systems without memfd sealing

* added libnetdata/uuid directory

* move datetime formatters to libnetdata

* add missing files

* link the makefiles in libnetdata

* added uuid_parse_flexi() to parse UUIDs with and without hyphens; the web server now read X-Transaction-ID and uses it for functions and web responses

* added stream receiver, sender, proc plugin and pluginsd log stack

* iso8601 advanced usage; line_splitter module in libnetdata; code cleanup

* add message ids to streaming inbound and outbound connections

* cleanup line_splitter between lines to avoid logging garbage; when killing children, kill them with SIGABRT if internal checks is enabled

* send SIGABRT to external plugins only if we are not shutting down

* fix cross cleanup in pluginsd parser

* fatal when there is a stack error in logs

* compile netdata with -fexceptions

* do not kill external plugins with SIGABRT

* metasync info logs to debug level

* added severity to logs

* added json output; added options per log output; added documentation; fixed issues mentioned

* allow memfd only on linux

* moved journal low level functions to journal.c/h

* move health logs to daemon.log with proper priorities

* fixed a couple of bugs; health log in journal

* updated docs

* systemd-cat-native command to push structured logs to journal from the command line

* fix makefiles

* restored NETDATA_LOG_SEVERITY_LEVEL

* fix makefiles

* systemd-cat-native can also work as the logger of Netdata scripts

* do not require a socket to systemd-journal to log-as-netdata

* alarm notify logs in native format

* properly compare log ids

* fatals log alerts; alarm-notify.sh working

* fix overflow warning

* alarm-notify.sh now logs the request (command line)

* anotate external plugins logs with the function cmd they run

* added context, component and type to alarm-notify.sh; shell sanitization removes control character and characters that may be expanded by bash

* reformatted alarm-notify logs

* unify cgroup-network-helper.sh

* added quotes around params

* charts.d.plugin switched logging to journal native

* quotes for logfmt

* unify the status codes of streaming receivers and senders

* alarm-notify: dont log anything, if there is nothing to do

* all external plugins log to stderr when running outside netdata; alarm-notify now shows an error when notifications menthod are needed but are not available

* migrate cgroup-name.sh to new logging

* systemd-cat-native now supports messages with newlines

* socket.c logs use priority

* cleanup log field types

* inherit the systemd set INVOCATION_ID if found

* allow systemd-cat-native to send messages to a systemd-journal-remote URL

* log2journal command that can convert structured logs to journal export format

* various fixes and documentation of log2journal

* updated log2journal docs

* updated log2journal docs

* updated documentation of fields

* allow compiling without libcurl

* do not use socket as format string

* added version information to newly added tools

* updated documentation and help messages

* fix the namespace socket path

* print errno with error

* do not timeout

* updated docs

* updated docs

* updated docs

* log2journal updated docs and params

* when talking to a remote journal, systemd-cat-native batches the messages

* enable lz4 compression for systemd-cat-native when sending messages to a systemd-journal-remote

* Revert "enable lz4 compression for systemd-cat-native when sending messages to a systemd-journal-remote"

This reverts commit b079d53c11.

* note about uncompressed traffic

* log2journal: code reorg and cleanup to make modular

* finished rewriting log2journal

* more comments

* rewriting rules support

* increased limits

* updated docs

* updated docs

* fix old log call

* use journal only when stderr is connected to journal

* update netdata.spec for libcurl, libpcre2 and log2journal

* pcre2-devel

* do not require pcre2 in centos < 8, amazonlinux < 2023, open suse

* log2journal only on systems pcre2 is available

* ignore log2journal in .gitignore

* avoid log2journal on centos 7, amazonlinux 2 and opensuse

* add pcre2-8 to static build

* undo last commit

* Bundle to static
