68c1a0b9b4 lib/ignore, lib/model: Use an interface to detect file changes, improving tests
This solves the erratic test failures on model.TestIgnores by ensuring
that the ignore patterns are reloaded even in the face of unchanged
timestamps.

d6fbfc3545 lib/fs, lib/model, lib/scanner: Make scans cancellable (fixes #3965)
The folder already knew how to stop properly, but the fs.Walk() didn't
and can potentially take a very long time. This adds context support to
Walk and the underlying scanning stuff, and passes in an appropriate
context from above. The stop channel in model.folder is replaced with a
context for this purpose.

To test I added an infiniteFS that represents a large amount of data
(not actually infinite, but close) and verify that walking it is
properly stopped. For that to be implemented smoothly I moved out the
Walk function to it's own type, as typically the implementer of a new
filesystem type might not need or want to reimplement Walk.

It's somewhat tricky to test that this actually works properly on the
actual sendReceiveFolder and so on, as those are started from inside the
model and the filesystem isn't easily pluggable etc. Instead I've tested
that part manually by adding a huge folder and verifying that pause,
resume and reconfig do the right things by looking at debug output.

4253f22680 lib/scanner: Use fs.Filesystem for all operations
One more step on the path of the great refactoring. Touches rwfolder a
little bit since it uses the Lstat from fs as well, but mostly this is
just on the scanner as rwfolder is scheduled for a later refactor.

There are a couple of usages of fs.DefaultFilesystem that will in the
end become a filesystem injected from the top, but that comes later.

5c27796471 lib/model, lib/scanner: Properly ignore symlinks on Windows (fixes #4035)
Adds a unit test to ensure we don't scan symlinks on Windows. For the
rwfolder, trusts that the logic in the invalid check is correct and that
the check is actually called from the need loop.

c4ba580cbb all: Remove symlink support on Windows, SymlinksEnabled config
After this change,

- Symlinks on Windows are always unsupported. Sorry.

- Symlinks are always enabled on other platforms. They are just a small
  file like anything else. There is no need to special case them. If you
  don't want to sync some symlinks, ignore them.

- The protocol doesn't differentiate between different "types" of
  symlinks. If that distinction ever does become relevant the individual
  devices can figure it out by looking at the destination when they
  create the link.

It's backwards compatible in that all the old symlink types are still
understood to be symlinks, and the new SYMLINK type is equivalent to the
old SYMLINK_UNKNOWN which was always a valid way to do it.

9b1c592fb7 lib/scanner: Speed up weak hash
The rolling version of adler32 is just a wrapper around the standard
hash/adler32 when used in a non-rolling fashion, but it's inefficient as
it allocates a new hash instance for every Write(). This uses the
default version instead in the block hasher, and adds a test to verify
the result is the same as they were before. It reduces allocations by
88% and increases speed about 5%.

fa0101bd60 lib/protocol, lib/discover, lib/db: Use protocol buffer serialization (fixes #3080)
This changes the BEP protocol to use protocol buffer serialization
instead of XDR, and therefore also the database format. The local
discovery protocol is also updated to be protocol buffer format.

21e116aa45 lib/scanner: Refactor scanner.Walk API
The old usage pattern was to create a Walker with a bunch of attributes,
then call Walk() on it and nothing else. This extracts the attributes
into a Config struct and exposes a Walk(cfg Config) method instead, as
there was no reason to expose the state-holding walker type.

Also creates a few no-op implementations of the necessary interfaces
so that we can skip nil checks and simiplify things here and there.

Definitely look at this diff without whitespace.

So that the diff describes the changes that happened in actual as
compared to expected. The opposite is confusing.
