We would like to make it easier to accept multiple annotations.
Examples:
```
country("GB") && annotation(...)
annotated(annotated(X,...),...)
```

This patch makes it easier to configure existing placement rules only with string.
1. placement(n) rule can be used to reuse earlier definitions
2 .&& can be used in addition to all(n1,n2)
3. country(c) accepts exclusions (like '!RU'), regions ('EU','EEA'), all and none
See the 'full example' unit test, which uses all of these, in a realistic example.

There are cases when we would like to override the default placement=0 rule.
For example when we would like to exclude tagged nodes from the selection (by default).
Therefore we couldn't use a shortcut any more, we should always check the placement rules, even if we use placement=0.
TODO: we need to update common, and rename `EveryCountry` to `DefaultPlacement`, just to avoid confusion.

placement.AllowedCountry is the old way to specify placement, with the new approach we can use a more generic (dynamic method), which can check full node information instead of just the country code.
The 90% of this patch is just search and replace:
* we need to use NodeFilters instead of placement.AllowedCountry
* which means, we need an initialized PlacementRules available everywhere
* which means we need to configure the placement rules
The remaining 10% is the placement.go, where we introduced a new type of configuration (lightweight expression language) to define any kind of placement without code change.

All the files in uploadselection are (in fact) related to generic node selection, and used not only for upload,
but for download, repair, etc...
