d19b12d3fe lib/protocol: Buffer allocation when compressing (fixes #6146) (#6147)
We incorrectly gave a too small buffer to lz4.Compress, causing it to
allocate in some cases (when the data actually becomes larger when
compressed). This then panicked when passed to the buffer pool.

This ensures a buffer that is large enough, and adds tripwires closer to
the source in case this ever pops up again. There is a test that
exercises the issue.

lib/protocol: Use constants instead of init time hashing (fixes #5624) (#5625)
This constructs the map of hashes of zero blocks from constants instead
of calculating it at startup time. A new test verifies that the map is
correct.

24ffd8be99 all: Send Close BEP msg on intentional disconnect (#5440)
This avoids waiting until next ping and timeout until the connection is actually
closed both by notifying the peer of the disconnect and by immediately closing
the local end of the connection after that. As a nice side effect, info level
logging about dropped connections now have the actual reason in it, not a generic
timeout error which looks like a real problem with the connection.

all: Add receive only folder type (#5027)
Adds a receive only folder type that does not send changes, and where the user can optionally revert local changes. Also changes some of the icons to make the three folder types distinguishable.

Add LocalFlags to FileInfo (#4952)
We have the invalid bit to indicate that a file isn't good. That's enough for remote devices. For ourselves, it would be good to know sometimes why the file isn't good - because it's an unsupported type, because it matches an ignore pattern, or because we detected the data is bad and we need to rescan it.

Or, and this is the main future reason for the PR, because it's a change detected on a receive only device. We will want something like the invalid flag for those changes, but marking them as invalid today means the scanner will rehash them. Hence something more fine grained is required.

This introduces a LocalFlags fields to the FileInfo where we can stash things that we care about locally. For example,

    FlagLocalUnsupported = 1 << 0 // The kind is unsupported, e.g. symlinks on Windows
    FlagLocalIgnored     = 1 << 1 // Matches local ignore patterns
    FlagLocalMustRescan  = 1 << 2 // Doesn't match content on disk, must be rechecked fully

The LocalFlags fields isn't sent over the wire; instead the Invalid attribute is calculated based on the flags at index sending time. It's on the FileInfo anyway because that's what we serialize to database etc.

The actual Invalid flag should after this just be considered when building the global state and figuring out availability for remote devices. It is not used for local file index entries.

all: Simultaneously walk fs and db on scan (fixes #2571, fixes #4573) (#4584)
When scanner.Walk detects a change, it now returns the new file info as well as the old file info. It also finds deleted and ignored files while scanning.
Also directory deletions are now always committed to db after their children to prevent temporary failure on remote due to non-empty directory.

6809d38cde lib/protocol: Revert protobuf encoder changes in v0.14.17 (fixes #3855)
The protobuf encoder now produces packed arrays for things like []int32,
which is actually correct according to the proto3 spec. However
Syncthing v0.14.16 and earlier doesn't support this. This reverts the
encoding change, but keeps the updated decoder so that we are both more
compatible with other proto3 implementations and can move to the updated
encoder in the future.

ea87bcefd6 lib/protocol, lib/model: Implement high precision time stamps (fixes #3305)
This adds a new nanoseconds field to the FileInfo, populates it during
scans and sets the non-truncated time in Chtimes calls.

The actual file modification time is defined as modified_s seconds +
modified_ns nanoseconds. It's expected that the modified_ns field is <=
1e9 (that is, all whole seconds should go in the modified_s field) but
not really enforced. Given that it's an int32 the timestamp can be
adjusted += ~2.9 seconds by the modified_ns field...

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.

d507126101 lib/protocol: Understand older/newer Hello messages (fixes #3287)
This is in preparation for future changes, but also improves the
handling when talking to pre-v0.13 clients. It breaks out the Hello
message and magic from the rest of the protocol implementation, with the
intention that this small part of the protocol will survive future
changes.

To enable this, and future testing, the new ExchangeHello function takes
an interface that can be implemented by future Hello versions and
returns a version indendent result type. It correctly detects pre-v0.13
protocols and returns a "too old" error message which gets logged to the
user at warning level:

   [I6KAH] 09:21:36 WARNING: Connecting to [...]:
     the remote device speaks an older version of the protocol (v0.12) not
     compatible with this version

Conversely, something entirely unknown will generate:

   [I6KAH] 09:40:27 WARNING: Connecting to [...]:
     the remote device speaks an unknown (newer?) version of the protocol

The intention is that in future iterations the Hello exchange will
succeed on at least one side and ExchangeHello will return the actual
data from the Hello together with ErrTooOld and an even more precise
message can be generated.
