"private" collation types: not "available", avoid creation of binary data in imports

Description

The fix for had issues, so was rolled back. Resurrecting it in this bug.

Original description:

One part of the description of import on the following page was omitted in 1.9. It needs needs to be added to 2.0, before we add actual <import> statements.

That is the following:
Add private as an additional attribute for `<settings>`:
`<settings private="true"> // mirroring <transform>'s private attribute`

We should not (need to, have to) add "private" tailorings to bcp47/collation.xml.

CLDR meeting 2014-04-23: (some discussion bullets omitted here)

Markus proposes to distinguish for-import-only rules from create-a-sort-order rules via a naming convention rather than flags in the data

  • See email “CLDR/ICU proposal: collation rules for import only”

  • Proposal: First character in collation type == digit ‘0’ means for-import-only, e.g., “0kana”; no “private” XML attribute, no adding such internal types to bcp47/collation.xml

  • Survey tool - suppress naming (coverage)

  • Rationale/details in email

  • `<collation type=”private-foo”>`

  • Approved de-u-co-private-foo

  • CLDR `<collation type=”private-kana”>` `<import source=”ja” type=”private-kana”>` ICU `[ja-u-co-private-kana|import]`
