[feature/localsearch] Local account-wide search using custom queries (#…

…933)

* Port changes from feature/globalsearch to milestone/11.6

* - clean up QueryFileListTableViewController.swift
- replace all/folder text in scope selection with icons on iOS 13+

* - SortMethod
	- turn localizedName from a function into a property
	- add sortPropertyName to simplify construction of custom OCQuerys
- ClientQueryViewController
	- add sort property, sort order and result limits to OCQueryCondition
	- refresh search query when changing sort order and peak results

* - UIView+Extension: add simply methods to start/stop a pulsing effect on a view
- ServerListTableViewController
	- add user activity to allow state restoring to server list (previously only *always* to the last opened bookmark)
	- remove auto login code for pre-iOS 13 (in iOS 13 that's handled by scene/state restoration)
	- add inline status reporting for database migrations
- SceneDelegate: add support to state restore to server list
- ClientQueryViewController
	- switch to search tokenizer to construct OCQueryCondition
	- make sure sort / search options are no longer hidden when showing large "No results" message
- ClientRootViewController
	- add support for migration progress reporting / OCCoreBusyStatusHandler passing
	- fix OCFileProviderServiceStandby leak if OCCoreManager returns a request with an error
- FileProvider extension
	- return an error when trying to access an account whose database needs migration
	- handle case where no OCCore is available
- MessageView: add option to show messages with insets at the edges
- NSDate+ComputedTimes:
	- simplified computation of beginning of days, weeks, months and years, with support for offsets
	- add unit test
- OCQueryCondition+SearchSegmenter:
	- segmentation of search queries into terms and "keywords"
	- supports placing terms in "" as well as unclosed "
	- keyword support to filter for:
		- files (:file), folders (:folder),
		- images (:image), video (:video)
		- time frames (:today, :week, :month, :year)
		- dynamic time frames (:7d, :2w, :1m, :1y, days:7, weeks:2, month:1, year:1, …)
		- file types/suffixes (type:jpg)
	- add unit test

* - add "Show more results" row at the end of the search result list if there could be more results

* - Cleanup more cell identifiers

* - QueryFileListTableViewController: search remains active after choosing an item and then navigating back to search
- ClientQueryViewController: adapt to QueryFileListTableViewController changes

* SDK update to fix OCCore stop bug

* - BreadCrumbTableViewController
	- add navigationHandler property to allow custom navigation actions to get triggered by the breadcrumb view
- ClientItemCell
	- add reveal button support
- ClientQueryViewController / QueryFileListTableViewController
	- allow providing an item to reveal and highlight
	- allow specifying if bread crumbs should push new view controllers
	- show reveal arrows for custom queries

* - fix issue of stopped custom query after revealing an item and returning
- use search term segmentation also for folder search (via OCQueryCondition+Item)

* - OCBookmark+AppExtensions: check if displayName and userName have at least one character before using them

* - update SDK
- add concept and property of activeQuery to QueryFileListTableViewController
- adopt activeQuery in ClientQueryViewController to prevent QueryFileListTableViewController from controlling the customSearchQuery / run into conflicts
- resolve issue where a "Stopped" status was displayed sometimes when returning from a revealed search result

* - more differentiated status 503 handling (owncloud/enterprise#4476) via SDK update

* - NSDate+ComputedTimes
	- add date parsing for strings following [year]-[[month][-[day]]] syntax
	- clarify all other method names
- NSString+ByteCountParser: parse strings into byte counts, support TB, TiB, GB, GiB, MB, MiB, B and bytes-without-B
- OCQueryCondition+SearchSegmenter
	- add support for localized keywords in local search
	- clean up keywords, removing kind-of-duplicates
	- add new keywords:
		- after: return items last modified after the given date
		- before: return items last modified before the given date
		- on: return items last modified on the given date
		- smaller: return items less than this size
		- greater: return items greater than this size

* - Update SDK to fix Service Unavailable error handling

* - update SDK to add item sync info scrubbing capabilities
- address Xcode / linter warnings

* OCQueryCondition+SearchSegmenter:
- add full localization + normalization of keywords
- add English and German localization

* - update SDK
- remove leftover code

* - QueryFileListTableViewController: remove unneeded/conflicting searchScope initialization
- added missing localizations

* Code review suggestion for PR #933:
- hide multiselect button, when search is active
- use labels instead of images for search scope segmented control
- changed more button width for better UI alignment
- changed multiselect button width for better touch experience

* - change search field placeholder depending on selected scope

* - fixed showing and executing keyboard shortcuts when search is active in file list (was not shown, because action was not available in performing class)
- added "Toggle Search Scope" keyboard shortcut
- scroll file list to top, when search will be activated

* - comment out parts of KeyCommands that seem to interfere with entry of search text, jumping to entries with the letters instead
- scroll to top when results change
- add support for negating search terms by prefixing them with "-", i.e. "-word" to exclude results with "word" in it

* - disable keyboard shortcuts for letters, if search is active
- make search field first responder, when toggle search scope

* fixed search field cursor tint color

* - logging improvements: use OCFileOpLog to log file operation in OCCore+BundleImport.m
- update SDK

* - fix finding (1) in #933 via SDK update

* - fix misplaced sortbar (finding (3) in #933)

* - OCQueryCondition+SearchSegmenter: accept more possible quotation marks when segmenting searches

* OCQueryCondition+SearchSegmenter: allow inactivation of keywords through quotation, make it possible to still negate such searches

* - remove accidentally entered ":" that prevented compilation

* fixed QA finding (8): keyboard commands for search and sort order where missing in directory picker

* - SortBar: new allowMultiSelect property to control whether multi select should be available, defaulting to true
- QueryFileListTableViewController, ClientQueryViewController: allow efficient subclassing of relevant parts of the reveal feature
- ClientDirectoryPickerViewController: provide implementations of relevant reveal subclassing points, disable multi-select (fixing finding (7) and (9) in #933)

* - update SDK to add database support for ownerUserName
- search segmenter: add support for owner keyword, incl. localization

* fixed duplicated keyboard commands:
changed keyboard command for toggle search order and share item

* added changelog entry

* Calens changelog updated
