A benchmark in my sound repository with `git-annex view feedtitle=*`
took 2:52 wall clock time before and 1:58 after. Though it still only used
130% of CPU.
This is the same kind of optimisation that is in seekFilteredKeys, though
that precaches location logs while this streams the metadata logs direct
to parsing them.
seekFilteredKeys contains more streaming, to find the annexed files, and
this could be further sped up with similar streaming.

* sync: When run in a view branch, refresh the view branch to reflect any
changes that have been made to the parent branch or metadata.
This is basically working, but probably needs some more work to deal with
all the edge cases of things sync does.

* view: New field?=glob and ?tag syntax that includes a directory "_"
in the view for files that do not have the specified metadata set.
* Added annex.viewunsetdirectory git config to change the name of the
"_" directory in a view.
When in a view using the new syntax, old git-annex will fail to parse the
view log. It errors with "Not in a view.", which is not ideal. But that
only affects view commands.
annex.viewunsetdirectory is included in the View for a couple of reasons.
One is to avoid needing to warn the user that it should not be changed when
in a view, since that would confuse git-annex. Another reason is that it
helped with plumbing the value through to some pure functions.
annex.viewunsetdirectory is actually mangled the same as any other view
directory. So if it's configured to something like "N/A", there won't be
multiple levels of directories, which would also confuse git-annex.

I've long been asked for `git-annex find --all` or something like that,
but pushed back on it because I feel that the command is analagous to
find(1) and so it would be surprising for it to list keys rather than
files. So instead, add a new findkeys subcommand.
Note that the use of withKeyOptions is rather strange because usually
that is used to fall back to --all rather than listing files, but here
it's made to default to --all like behavior and never list files.
A performance thing that could be improved is that withKeyOptions
always reads and caches location logs. But findkeys with no options does
not need them, so it could be made faster. That caching does speed up
options like --in though. This is really just a subset of a more general
performance thing that --all reads location logs sometimes unncessarily.
Anyway, it needs to read the location log in order to checkDead,
and it seems good that findkeys does skip dead keys.
Also, cleaned up comments on git-annex-find man page asking for --all
option.

Note that when this is specified and an older git-annex is used to
enableremote such a special remote, it will simply ignore the cost= field
and use whatever the default cost is.
In passing, fixed adb to support the remote.name.cost and
remote.name.cost-command configs.
