Add indirection for large version vectors. (#6376)
This adds indirection of large version vectors in the same manner as we
already to block lists. The effect is the same: less duplicated data in
some situations.

To mitigate the impact for when this indirection
wouldn't be needed I've added an indirection cutoff for both blocks and
the new version vector stuff: we don't do the indirection at all for
small block lists or small version vectors, instead storing it directly
like we used to do. This is faster for small files and small setups.

lib/db: Make database GC a service, stop on Stop() (#6518)
This makes the GC runner a service that will stop fairly quickly when
told to.

As a bonus, STTRACE=app will print the service tree on the way out,
including any errors they've flagged.

lib/db: Don't whack blocks when putting truncated file (#6434)
As of the latest database checker we are again putting files without
blocks. I'm not 100% convinced that's a great idea, but we also do it
for ignored files apparently so it looks like we probably should support
it. This adds an escape hatch that must be manually enabled...

all: Tweak error creation (#6391)
- In the few places where we wrap errors, use the new Go 1.13 "%w"
  construction instead of %s or %v.

- Where we create errors with constant strings, consistently use
  errors.New and not fmt.Errorf.

- Remove capitalization from errors in the few places where we had that.

lib/db: Correct metadata recalculation (fixes #6381) (#6382)
If we decide to recalculate the metadata we shouldn't start from
whatever we loaded from the database, as that data is wrong. We should

lib/db: Slightly improve indirection (ref #6372) (#6373)
I was working on indirecting version vectors, and that resulted in some
refactoring and improving the existing block indirection stuff. We may
or may not end up doing the version vector indirection, but I think
these changes are reasonable anyhow and will simplify the diff
significantly if we do go there. The main points are:

- A bunch of renaming to make the indirection and GC not about "blocks"
  but about "indirection".

- Adding a cutoff so that we don't actually indirect for small block
  lists. This gets us better performance when handling small files as it
  cuts out the indirection for quite small loss in space efficiency.

- Being paranoid and always recalculating the hash on put. This costs
  some CPU, but the consequences if a buggy or malicious implementation
  silently substituted the block list by lying about the hash would be bad.

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)

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.
