Summary:
We don't need to create double-indirection when accepting `>list` arguments.
This tends to force callers into creating new Vecs of references here and
there.
Since I was in here fixing D17286200, I figured I might as well do this too.

Summary:
That's something we'd like to do for a while - for each request track how many requests it
sends to our storages (i.e. manifold and xdb). That might make perf debugging easier.
There's a concern that it might increase cpu usage, and I'll run a canary to check
if it's the case.

Start moving mercurial related stuff to `mercurial` directory:
- rename `mercurial` to `mercurial_revlog` and moved to `/mercurial/revlog`
- move `mercurial_types` to `/mercurial/types`
- move `mercurial_bundles` to `/mercurial/bundels`

Summary:
The stats prefix for bonsai hg mapping is "bonsai-hg-mapping" in lib.rs and
"bonsai_hg_mapping" in caching.rs. Convert lib.rs's prefix to match that of caching.rs,
making it easier to find stats.

Summary:
We don't control whatever `get_from_db` will do when asked to fetch no data. We can hope it'll do the smart thing and not hit the DB nor increment any monitoring counters.
This can be problematic, because it can result in confusing data in ODS. See T45198435 for a recent example of this.

Add a LABEL constant to the SqlConstructors trait to make it easier to identify
which table is being used, for stats and logging.

Summary:
AnyMapping sql requests was unbearably slow - it took 1 seconds to finish.
Replacing it with two normal requests works much faster.
Note that it affected performance only if there was already an entry in the
mapping table
