Backups (#1685)
* Add zstd dep

* Implement backend backup with zstd

* Implement backup thinning

* Write backup meta

* Use new file ending anki21b

* Asynchronously backup on collection close in Rust

* Revert "Add zstd dep"

This reverts commit 3fcb2141d2be15f907269d13275c41971431385c.

* Add zstd again

* Take backup col path from col struct

* Fix formatting

* Implement backup restoring on backend

* Normalize restored media file names

* Refactor `extract_legacy_data()`

A bit cumbersome due to borrowing rules.

* Refactor

* Make thinning calendar-based and gradual

* Consider last kept backups of previous stages

* Import full apkgs and colpkgs with backend

* Expose new backup settings

* Test `BackupThinner` and make it deterministic

* Mark backup_path when closing optional

* Delete leaky timer

* Add progress updates for restoring media

* Write restored collection to tempfile first

* Do collection compression in the background thread

This has us currently storing an uncompressed and compressed copy of
the collection in memory (not ideal), but means the collection can be
closed without waiting for compression to complete. On a large collection,
this takes a close and reopen from about 0.55s to about 0.07s. The old
backup code for comparison: about 0.35s for compression off, about
8.5s for zip compression.

* Use multithreading in zstd compression

On my system, this reduces the compression time of a large collection
from about 0.55s to 0.08s.

* Stream compressed collection data into zip file

* Tweak backup explanation

+ Fix incorrect tab order for ignore accents option

* Decouple restoring backup and full import

In the first case, no profile is opened, unless the new collection
succeeds to load.
In the second case, either the old collection is reloaded or the new one
is loaded.

* Fix number gap in Progress message

* Don't revert backup when media fails but report it

* Tweak error flow

* Remove native BackupLimits enum

* Fix type annotation

* Add thinning test for whole year

* Satisfy linter

* Await async backup to finish

* Move restart disclaimer out of backup tab

Should be visible regardless of the current tab.

* Write restored collection in chunks

* Refactor

* Write media in chunks and refactor

* Log error if removing file fails

* join_backup_task -> await_backup_completion

* Refactor backup.rs

* Refactor backup meta and collection extraction

* Fix wrong error being returned

* Call sync_all() on new collection

* Add ImportError

* Store logger in Backend, instead of creating one on demand

init_backend() accepts a Logger rather than a log file, to allow other
callers to customize the logger if they wish.

In the future we may want to explore using the tracing crate as an
alternative; it's a bit more ergonomic, as a logger doesn't need to be
passed around, and it plays more nicely with async code.

* Sync file contents prior to rename; sync folder after rename.

* Limit backup creation to once per 30 min

* Use zstd::stream::copy_decode

* Make importing abortable

* Don't revert if backup media is aborted

* Set throttle implicitly

* Change force flag to minimum_backup_interval

* Don't attempt to open folders on Windows

* Join last backup thread before starting new one

Also refactor.

* Disable auto sync and backup when restoring again

* Force backup on full download

* Include the reason why a media file import failed, and the file path

- Introduce a FileIoError that contains a string representation of
the underlying I/O error, and an associated path. There are a few
places in the code where we're currently manually including the filename
in a custom error message, and this is a step towards a more consistent
approach (but we may be better served with a more general approach in
the future similar to Anyhow's .context())
- Move the error message into importing.ftl, as it's a bit neater
when error messages live in the same file as the rest of the messages
associated with some functionality.

* Fix importing of media files

* Minor wording tweaks

* Save an allocation

I18n strings with replacements are already strings, so we can skip the
extra allocation. Not that it matters here at all.

* Terminate import if file missing from archive

If a third-party tool is creating invalid archives, the user should know
about it. This should be rare, so I did not attempt to make it
translatable.

* Skip multithreaded compression on small collections

5df684fa6b rework backend codegen to support multiple services; split out sched
Rust requires all methods of impl Trait to be in a single file, which
means we had a giant backend/mod.rs covering all exposed methods. By
using separate service definitions for the separate areas, and updating
the code generation, we can split it into more manageable chunks -
this commit starts with the scheduling code.

In the long run, we'll probably want to split up the protobuf file into
multiple files as well.

Also dropped want_release_gil() from rsbridge, and the associated method
enum. While it allows us to skip the thread save/restore and mutex unlock/
lock, it looks to only be buying about 2.5% extra performance in the
best case (tested with timeit+format_timespan), and the majority of
the backend methods deal with I/O, and thus were already releasing the
GIL.

35840221bb tweak search wording and tidy up API
- SearchTerm -> SearchNode
- Operator -> Joiner; share between messages
- build_search_string() supports specifying AND/OR as a convenience
- group_searches() makes it easier to negate

59ccfe5918 more search bikeshedding
While implementing the overdue search, I realised it would be nice to
be able to construct a search string with OR and NOT searches without
having to construct each part individually with build_search_string().

Changes:

- Extends SearchTerm to support a text search, which will be parsed
by the backend. This allows us to do things like wrap text in a group
or NOT node.
- Because SearchTerm->Node conversion can now fail with a parsing error,
it's switched over to TryFrom
- Switch concatenate_searches and replace_search_term to use SearchTerms,
so that they too don't require separate string building steps.
- Remove the unused normalize_search()
- Remove negate_search, as this is now an operation on a Node, and
users can wrap their search in SearchTerm(negated=...)
- Remove the match_any and negate args from build_search_string

Having done all this work, I've just realised that perhaps the original
JSON idea was more feasible than I first thought - if we wrote it out
to a string and re-parsed it, we would be able to leverage the existing
checks that occur at parsing stage.

fbd91b22f5 tidy up UTC offset handling/timing calculations
- use the TimestampSecs newtype instead of raw i64s
- use FixedOffset instead of a minutes_west offset
- check localOffset each time the timing is calculated, and set it
if it's stale - even for v1.
- check for and fix missing rollover when calculating timing
- stop explicitly passing localOffset in the sync/start call
