revset: explicitely tag alias arguments for expansion

The current revset alias expansion code works like:
1- Get the replacement tree
2- Substitute the variables in the replacement tree
3- Expand the replacement tree

It makes it easy to substitute alias arguments because the placeholders
are always replaced before the updated replacement tree is expanded
again. Unfortunately, to fix other alias expansion issues, we need to
reorder the sequence and delay the argument substitution. To solve this,
a new "virtual" construct called _aliasarg() is introduced and injected
when parsing the aliases definitions. Only _aliasarg() will be
substituted in the argument expansion phase instead of all regular
matching string. We also check user inputs do not contain unexpected
_aliasarg() instances to avoid argument injections.

Preparing the subrepository 'sub2'

  $ hg init sub2
  $ echo sub2 > sub2/sub2
  $ hg add -R sub2
  adding sub2/sub2 (glob)
  $ hg commit -R sub2 -m "sub2 import"

Preparing the 'sub1' repo which depends on the subrepo 'sub2'

  $ hg init sub1
  $ echo sub1 > sub1/sub1
  $ echo "sub2 = ../sub2" > sub1/.hgsub
  $ hg clone sub2 sub1/sub2
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg add -R sub1
  adding sub1/.hgsub (glob)
  adding sub1/sub1 (glob)
  $ hg commit -R sub1 -m "sub1 import"

Preparing the 'main' repo which depends on the subrepo 'sub1'

  $ hg init main
  $ echo main > main/main
  $ echo "sub1 = ../sub1" > main/.hgsub
  $ hg clone sub1 main/sub1
  updating to branch default
  cloning subrepo sub2 from $TESTTMP/sub2
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg add -R main
  adding main/.hgsub (glob)
  adding main/main (glob)
  $ hg commit -R main -m "main import"

Cleaning both repositories, just as a clone -U

  $ hg up -C -R sub2 null
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg up -C -R sub1 null
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ hg up -C -R main null
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ rm -rf main/sub1
  $ rm -rf sub1/sub2

Clone main

  $ hg clone main cloned
  updating to branch default
  cloning subrepo sub1 from $TESTTMP/sub1
  cloning subrepo sub1/sub2 from $TESTTMP/sub2 (glob)
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved

Checking cloned repo ids

  $ printf "cloned " ; hg id -R cloned
  cloned 7f491f53a367 tip
  $ printf "cloned/sub1 " ; hg id -R cloned/sub1
  cloned/sub1 fc3b4ce2696f tip
  $ printf "cloned/sub1/sub2 " ; hg id -R cloned/sub1/sub2
  cloned/sub1/sub2 c57a0840e3ba tip

debugsub output for main and sub1

  $ hg debugsub -R cloned
  path sub1

  path sub2
   source   ../sub2
   revision c57a0840e3badd667ef3c3ef65471609acb2ba3c

Modifying deeply nested 'sub2'

  $ echo modified > cloned/sub1/sub2/sub2
  $ hg commit --subrepos -m "deep nested modif should trigger a commit" -R cloned
  committing subrepository sub1
  committing subrepository sub1/sub2 (glob)

Checking modified node ids
