lib/upnp: Exit quicker (#6339) 
During NAT discovery we block for 10s (NatTimeoutS) before returning.
This is mostly noticeable when Ctrl-C:ing a Syncthing directly after
startup as we wait for those ten seconds before shutting down. This
makes it check the context a little bit more frequently.

lib/db: Keep metadata better in sync (ref #6335) (#6337) 
This adds metadata updates to the same write batch as the underlying
file change. The odds of a metadata update going missing is greatly
reduced.

Bonus change: actually commit the transaction in recalcMeta.

lib/db: Recover sequence number and metadata on startup (fixes #6335) (#6336) 
lib/db: Recover sequence number and metadata on startup (fixes #6335)

If we crashed after writing new file entries but before updating
metadata in the database the sequence number and metadata will be wrong.
This fixes that.

lib/db: Don't leak snapshot when closing (#6331) 
We could potentially get a snapshot and then fail to get a releaser,
leaking the snapshot. This takes the releaser first and makes sure to
release it on snapshot error.

lib/db: Use Commit() instead of commit() (#6330) 
The readWriteTransaction offered both commit() (the one to use) and
Commit() (via embedding) where the latter didn't close the read
transaction. This removes the lower cased variant in order to prevent
the mistake.

The only place where the mistake was made was the new gc runner, where
it would leave a read snapshot open forever.

lib/fs, lib/model: Rewrite RecvOnly tests (#6318) 
During some other work I discovered these tests weren't great, so I've
rewritten them to be a little better. The real changes here are:

- Don't play games with not starting the folder and such, and don't
  construct a fake folder instance -- just use the one the model has. The
  folder starts and scans but the folder contents are empty at this point
  so that's fine.

- Use a fakefs instead of a temp dir.

- To support the above, implement a fakefs option `?content=true` to
  make the fakefs actually retain written content. Use sparingly,
  obviously, but it means the fakefs can usually be used instead of an
  on disk real directory.

lib/model: Add global request limiter (fixes #6302) (#6303) 
This adds a new config with the simple and concise name
maxConcurrentIncomingRequestKiB. This limits how many bytes we have "in
the air" in the form of response data being read and processed.

After some testing I think that not having this limiter is seldom a
great idea and thus I propose a default value of 256 MiB for this new
setting.

I also refactored the folder IO limiter to be a model/folder attribute
instead of a package global.

lib/config, lib/model: Limit concurrent pulls (fixes #5914) (#6290) 
Adds a new folder state "Waiting to Sync" in the same vein as the
existing "Waiting to Scan". This vastly improves performances in the
rare cases when there are lots and lots of folders operating.

lib/db: Configurable block GC time (#6295) 
Also retain the interval over restarts by storing last GC time in the
database. This to make sure that GC eventually happens even if the
interval is configured to a long time (say, a month).

lib/db: Deduplicate block lists in database (fixes #5898) (#6283) 
* lib/db: Deduplicate block lists in database (fixes #5898)

This moves the block list in the database out from being just a field on
the FileInfo to being an object of its own. When putting a FileInfo we
marshal the block list separately and store it keyed by the sha256 of
the marshalled block list. When getting, if we are not doing a
"truncated" get, we do an extra read and unmarshal for the block list.

Old block lists are cleared out by a periodic GC sweep. The alternative
would be to use refcounting, but:

- There is a larger risk of getting that wrong and either dropping a
  block list in error or keeping them around forever.

- It's tricky with our current database, as we don't have dirty reads.
  This means that if we update two FileInfos with identical block lists in
  the same transaction we can't just do read/modify/write for the ref
  counters as we wouldn't see our own first update. See above about
  tracking this and risks about getting it wrong.

GC uses a bloom filter for keys to avoid heavy RAM usage. GC can't run
concurrently with FileInfo updates so there is a new lock around those
operation at the lowlevel.

The end result is a much more compact database, especially for setups
with many peers where files get duplicated many times.

This is per-key-class stats for a large database I'm currently working
with, under the current schema:

Note 7.4 GB of data in class 00, total size 9.2 GB. After running the
migration we get this instead:

```

Class 00 is now down to 2.6 GB, with just 61 MB added in class 0d.

There will be some additional reads in some cases which theoretically
hurts performance, but this will be more than compensated for by smaller
writes and better compaction.

On my own home setup which just has three devices and a handful of
folders the difference is smaller in absolute numbers of course, but
still less than half the old size:

```
 0x00:  297122 items,  20894 KB keys + 306860 KB data, 70 B + 1032 B avg, 103237 B max
 0x01:  115299 items,   7738 KB keys +  17542 KB data, 67 B +  152 B avg,    419 B max
 0x02: 1430537 items, 121223 KB keys +   5722 KB data, 84 B +    4 B avg,    253 B max
 ...
 Total 1947412 items, 151268 KB keys + 337485 KB data.
```

to:

```
 0x00:  297122 items,  20894 KB keys +  37038 KB data, 70 B +  124 B avg,    520 B max
 0x01:  115299 items,   7738 KB keys +  17542 KB data, 67 B +  152 B avg,    419 B max
 0x02: 1430537 items, 121223 KB keys +   5722 KB data, 84 B +    4 B avg,    253 B max
 ...
 0x0d:   18041 items,    595 KB keys +  71964 KB data, 33 B + 3988 B avg, 101109 B max
