Add support for sanitizers at compile time (and fix some issues) (#2599)

* Add an option to enable sanitizer at compile time

* Fix singleton classes initialization

* Revert r5378 - issue #1068 - to avoid having duplicate symbols exported by modules, that may cause a crash

* Fix cast in KviTalIconAndRichTextItemDelegate (used by both QListWidget and QTreeWidget)

* ScriptEditor: don't leak a timer for every script editor widget

* Add support for memory and thread sanitizers

* Fix sanitizer

* KviSignalhandler: don't leak the whole object

* Remove debug warning when a single message is longer than 512 bytes.
As per https://ircv3.net/specs/extensions/message-tags.html#size-limit , message tags can prepend a whooping 8kbs of "tags" (header data) to each message.

* Avoid initialization loop between KviLocale and KviMessageCatalogue. Assume all .po files are UTF8. This is already a requirement since about a decade.

* KviInputEditor: don't leak the undo/redo stacks

KviInputEditor: don't leak the undo/redo stacks - rework using smart pointers

* Fix typo
