lib/config, lib/connections: Add optional connection limits (fixes #7176) (#7223) 
This adds two new configuration options:

    // The number of connections at which we stop trying to connect to more
    // devices, zero meaning no limit. Does not affect incoming connections.
    ConnectionLimitEnough int

    // The maximum number of connections which we will allow in total, zero
    // meaning no limit. Affects incoming connections and prevents
    // attempting outgoing connections.
    ConnectionLimitMax int

These can be used to limit the number of concurrent connections in
various ways.

lib/fs: Use file clone ioctl wrappers and types from golang.org/x/sys/unix (#7000) 
Use the IoctlFileClone and IoctlFileCloneRange ioctl wrappers and the
FileCloneRange type provided by golang.org/x/sys/unix instead of
locally implementing them. This also allows to re-enable the code for
ppc/ppc64/ppc64le again (see commit 758a1a6a37 ("lib/fs: Disable ioctl
on ppc (fixes #6898) (#6901)")) since golang.org/x/sys/unix internally
uses the correct FICLONE and FICLONERANGE values depending on $GOARCH.

lib/db: Use SipHash to deal with hash collision in GC (#6826) 
If the GC finds a key k that it wants to keep, it records that in a
Bloom filter. If a key k' can be removed but its hash collides with k,
it will be kept. Since the old Bloom filter code was completely
deterministic, the next run would encounter the same collision, assuming
k must still be kept.

A randomized hash function that uses all the SHA-256 bits solves this
problem: the second run has a non-zero probability of removing k', as
long as the Bloom filter is not completely full.

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:

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:
