Implement database abstraction, error checking (ref #5907) (#6107)
This PR does two things, because one lead to the other:

- Move the leveldb specific stuff into a small "backend" package that
defines a backend interface and the leveldb implementation. This allows,
potentially, in the future, switching the db implementation so another
KV store should we wish to do so.

- Add proper error handling all along the way. The db and backend
packages are now errcheck clean. However, I drew the line at modifying
the FileSet API in order to keep this manageable and not continue
refactoring all of the rest of Syncthing. As such, the FileSet methods
still panic on database errors, except for the "database is closed"
error which is instead handled by silently returning as quickly as
possible, with the assumption that we're anyway "on the way out".

cmd/syncthing: Implement log rotation (fixes #6104) (#6198)
Since we've taken upon ourselves to create a log file by default on
Windows, this adds proper management of that log file. There are two new
options:

  -log-max-old-files="3"    Number of old files to keep (zero to keep only current).
  -log-max-size="10485760"  Maximum size of any file (zero to disable log rotation).

The default values result in four files (syncthing.log, synchting.0.log,
..., syncthing.3.log) each up to 10 MiB in size. To not use log rotation
at all, the user can say --log-max-size=0.

f15a1528fc cmd/stbench: rm -r cmd/stbench (#6131)
This is apparently an old benchmarking tool. I'd forgotten about it.
Since 67b8ef1f3e the build script tries to
build all binaries explicitly by default, and this fails on Windows as
this tool doesn't build on Windows.

Kill it with fire.

cmd/stdiscosrv: Sort addresses before replication (fixes #6093) (#6094)
This makes sure addresses are sorted when coming in from the API. The
database merge operation still checks for correct ordering (which is
quick) and sorts if it isn't correct (legacy database record or
replication peer), but then does a copy first.

Tested with -race in production...

all: Update certificate lifetimes (fixes #6036) (#6078)
This adds a certificate lifetime parameter to our certificate generation
and hard codes it to twenty years in some uninteresting places. In the
main binary there are a couple of constants but it results in twenty
years for the device certificate and 820 days for the HTTPS one. 820 is
less than the 825 maximum Apple allows nowadays.

This also means we must be prepared for certificates to expire, so I add
some handling for that and generate a new certificate when needed. For
self signed certificates we regenerate a month ahead of time. For other
certificates we leave well enough alone.

cmd/*, lib/build: Set correct LongVersion (fixes #5993) (#5997)
The relay and discosrv didn't use the new lib/build package, now they
do. Conversely the lib/build package wasn't aware there might be other
users and hard coded the program name - now it's set by the build
script

build: Upgrade github.com/gogo/protobuf (#5994)
This is the result of:

- Changing build.go to take the protobuf version from the modules
  instead of hardcoded
- `go get github.com/gogo/protobuf@v1.3.0` to upgrade
- `go run build.go proto` to regenerate our code

90b70c7a16 lib/db: Use different defaults for larger databases (fixes #5966) (#5967)
This introduces a better set of defaults for large databases. I've
experimentally determined that it results in much better throughput in a
couple of scenarios with large databases, but I can't give any
guarantees the values are always optimal. They're probably no worse than
the defaults though.

cmd/stupgrades: Generate appropriate upgrade data (fixes #5924) (#5960)
This is a tiny tool to grab the GitHub releases info and generate a
more concise version of it. The conciseness comes from two aspects:

- We select only the latest stable and pre. There is no need to offer
  upgrades to versions that are older than the latest. (There might be, in
  the future, when we hit 2.0. We can revisit this at that time.)

- We use our structs to deserialize and reserialize the data. This means
  we remove all attributes that we don't understand and hence don't
  require.

All in all the new response is about 10% the size of the previous one and
avoids the issue where we only serve a bunch of release candidates and
no stable.

to insulate web browsers from the change (previously we just served the
raw reports from disk using Caddy).

f1a7dd766e all: Add comment to ensure correct atomics alignment (fixes #5813)
Per the sync/atomic bug note:

> On ARM, x86-32, and 32-bit MIPS, it is the caller's
> responsibility to arrange for 64-bit alignment of 64-bit words
> accessed atomically. The first word in a variable or in an
> allocated struct, array, or slice can be relied upon to be
> 64-bit aligned.

All atomic accesses of 64-bit variables in syncthing code base are
currently ok (i.e they are all 64-bit aligned).

Generally, the bug is triggered because of incorrect alignement
of struct fields. Free variables (declared in a function) are
guaranteed to be 64-bit aligned by the Go compiler.

To ensure the code remains correct upon further addition/removal
of fields, which would change the currently correct alignment, I
added the following comment where required:

     // atomic, must remain 64-bit aligned

See https://golang.org/pkg/sync/atomic/#pkg-note-BUG.

d0ab65a178 cmd/stcrashreceiver: Don't leak clients
Use a global raven.Client because they allocate an http.Client for each,
with a separate CA bundle and infinite connection idle time. Infinite
connection idle time means that if the client is never used again it
will always keep the connection around, not verifying whether it's
closed server side or not. This leaks about a megabyte of memory for
each client every created.

client.Close() doesn't help with this because the http.Client is still
around, retained by its own goroutines.

The thing with the map is just to retain the API on sendReport, even
though there will in practice only ever be one DSN per process
instance...

lib/ur: Implement crash (panic) reporting (fixes #959) (#5702)
* lib/ur: Implement crash (panic) reporting (fixes #959)

This implements a simple crash reporting method. It piggybacks on the
panic log files created by the monitor process, picking these up and
uploading them from the usage reporting routine.

A new config value points to the crash receiver base URL, which defaults
to "https://crash.syncthing.net/newcrash" (following the pattern of
"https://data.syncthing.net/newdata" for usage reports, but allowing us
to separate the service as required).

all: Fix some linter errors (#5499)
I'm working through linter complaints, these are some fixes. Broad
categories:

1) Ignore errors where we can ignore errors: add "_ = ..." construct.
you can argue that this is annoying noise, but apart from silencing the
linter it *does* serve the purpose of highlighting that an error is
being ignored. I think this is OK, because the linter highlighted some
error cases I wasn't aware of (starting CPU profiles, for example).

2) Untyped constants where we though we had set the type.

3) A real bug where we ineffectually assigned to a shadowed err.

4) Some dead code removed.

There'll be more of these, because not all packages are fixed, but the
diff was already large enough.
