mod_storage_xmlarchive: Limit search to smallest time range in case of inexact match
This should improve performance in case the exact days in the 'start'
and 'end' range are missing from the index.

--- summary: Multi-backend storage module (WIP) labels: - NeedDocs - Stage-Alpha ... Introduction ============ This module attemtps to provide a storage driver that is really multiple storage drivers. This could be used for storage error tolerance or caching of data in a faster storage driver. Configuration ============= An example: ``` {.lua} storage = "multi" storage_multi_policy = "all" storage_multi = { "memory", "internal", "sql" } ``` Here data would be first read from or written to [mod\_storage\_memory], then internal storage, then SQL storage. For reads, the first successful read will be used. For writes, it depends on the `storage_multi_policy` option. If set to `"all"`, then all storage backends must report success for the write to be considered successful. Other options are `"one"` and `"majority"`.
