editorconfig: Include the command used to normalize *.xml The double asterisk seems unnecessary.

editorconfig: Specify max line length to match luacheck settings

editorconfig: Explicitly specify preferred charset (UTF-8) Really should be the default everywhere by now, but doesn't hurt to be extra explicit

editorconfig: Add link to format description

mod_storage_sql: Remove completed TODO (testing UPSERT on PostgreSQL)

CHANGES: Move line about LuaSQLite3 to Storage section

CHANGES: Mention performance improvements for internal archives Specifically the index and more efficient delete. These are however still in need of testing.

mod_storage_internal: Implement efficient deletion of oldest archive items Using the new shift function in datamanager, either the oldest items are removed or all the later items are moved into a new file that replaces the old. Hidden behind a feature flag for now.

util.datamanager: Pad list writes to avoid crossing block boundaries By padding items so that they do not cross block boundaries, it becomes eaiser to delete whole blocks with fallocate() without cutting items in half, improving efficiency of such operations. Since list stores are used for message archives, where the most common deletion operation would be of the oldest entires, at the top of the file. With this, all blocks that contain items to be removed could be deleted without needing to read, delete and write out the whole file.

util.datamanager: Efficiently remove whole blocks to shift lists Using the new pposix.remove_blocks() it should be very performant to delete whole sections of a file, given a supporting file system.
