phases: add a 'registernew' method to set new phases

This new function will be used by code that adds new changesets. It ajusts the
phase boundary to make sure added changesets are at least in their target
phase (they end up in an higher phase if their parents are in a higher phase).

Having a dedicated function also simplify the phases tracking. All the new
nodes are passed as argument, so we know that all of them needs to have their
new phase registered. We also know that no other nodes will be affected, so no
extra computation are needed.

This function differ from 'retractboundary' where some nodes might change
phase while some other might not. It can also affect nodes not passed as
parameters.

These simplification also apply to the computation itself. For now we use
'_retractboundary' there by convenience, but we may introduces simpler code
later.

While registering new revisions, we still need to check the actual phases of
the added node because it might be higher than the target phase (eg: target is
draft but parent is secret).

We will migrate users over the next changesets.

$HOME/.cache/largefiles.

  $ hg init test

Whatever ... commit something so we can invoke merge when updating

  $ hg commit -m '3: Merge'

Updating from largefile to normal - no reason to prompt

  $ hg up -r 2
  getting changed largefiles
  0 largefiles updated, 0 removed
  1 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ cat foo

(the update above used to leave the working dir in a very weird state - clean it
  $ hg up -qr null
  $ hg up -qr 2
)

Updating from normal to largefile - no reason to prompt

  $ hg up -r 3

Systematic testing of merges involving largefiles:

Ancestor: normal  Parent: normal-id  Parent: large   result: large
Ancestor: normal  Parent: normal2    Parent: large   result: ?
Ancestor: large   Parent: large-id   Parent: normal  result: normal
Ancestor: large   Parent: large2     Parent: normal  result: ?

All cases should try merging both ways.

Prepare test repo:

  $ hg init merges
  $ cd merges

prepare cases with "normal" ancestor:

  $ hg up -qr null
  $ echo normal > f
  $ hg ci -Aqm "normal-ancestor"
  $ hg tag -l "normal-ancestor"
  $ touch f2
  $ hg ci -Aqm "normal-id"
  $ hg tag -l "normal-id"
  $ echo normal2 > f
  $ hg ci -m "normal2"
  $ hg tag -l "normal2"
  $ echo normal > f
  $ hg ci -Aqm "normal-same"
  $ hg tag -l "normal-same"
  $ hg up -qr "normal-ancestor"
  $ hg rm f
  $ echo large > f
  $ hg add --large f
  $ hg ci -qm "large"
  $ hg tag -l "large"

prepare cases with "large" ancestor:

  $ hg up -qr null
  $ echo large > f
  $ hg add --large f
  $ hg ci -qm "large-ancestor"
  $ hg tag -l "large-ancestor"
  $ touch f2
  $ hg ci -Aqm "large-id"
  $ hg tag -l "large-id"
  $ echo large2 > f

  $ hg ci -qAm "normal"
