main
global: Include lib-var-expand where needed
COPYING: Simplify and standardize copyright handling
lib-storage: Replace INDEX with mail_index_path setting
lib-storage: Removed mailbox list backend-specific mailbox name/pattern validation. The virtual name validity is independent of the backend. The physical name is always used for paths in filesystem, so it can also be verified with common code. Backend's mailbox_dir and storage's internal directories can also be checked. There's nothing else left really.
lib-storage: NOTIFY - Send events for mailboxes created and deleted between syncs
lib-storage: INDEX_LIST_STORAGE_CONTEXT now requires context
lib-storage: Avoid index refresh with mailbox_list_index_very_dirty_syncs=yes
lib-storage: mailbox-list-index - Add mailbox_list_index_parse_try()
lib-storage: Replace KEEP-NOSELECT with mailbox_list_drop_noselect setting
lib-storage: Added mailbox-list-notify API for tracking changes in all mailboxes. Requires mailbox_list_index=yes to work.
lib-storage: Fix NFC subscription rewrite for mUTF7 storage names
lib-storage: Remove unused mailbox_list_set_subscription_flags()
lib-storage: Cleaned up subscription listing internally. The subscription listing code is now mostly separated from the mailbox listing code.
