subrepo: make "_sanitize()" work

"_sanitize()" was introduced by 224e96078708 on "stable" branch, but
it has done nothing for sanitizing since 224e96078708.

"_sanitize()" assumes "Visitor" design pattern:

    "os.walk()" should invoke specified function ("v" in this case)
    for each directory elements under specified path

but "os.walk()" assumes "Iterator" design pattern:

    callers of it should drive loop to scan each directory elements
    under specified path by themselves with the returned generator
    object

Because of this mismatching, "_sanitize()" just discards the generator
object returned by "os.walk()" and does nothing for sanitizing.

This patch makes "_sanitize()" work.

This patch also changes the format of warning message to show each
unlinked files, for multiple appearances of "potentially hostile
.hg/hgrc".

Test encode/decode filters

  $ hg init
  $ cat > .hg/hgrc <<EOF
  > [encode]
  > not.gz = tr [:lower:] [:upper:]
  > *.gz = gzip -d
  > [decode]
  > not.gz = tr [:upper:] [:lower:]
  > *.gz = gzip
  > EOF
  $ echo "this is a test" | gzip > a.gz
  $ echo "this is a test" > not.gz
  $ hg add *
  $ hg ci -m "test"

no changes

  $ hg status
  $ touch *

no changes

  $ hg status

check contents in repo are encoded

  $ hg debugdata a.gz 0
  this is a test
  $ hg debugdata not.gz 0
  THIS IS A TEST

check committed content was decoded

  $ gunzip < a.gz
  this is a test
  $ cat not.gz
  this is a test
  $ rm *
  $ hg co -C
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved

check decoding of our new working dir copy

  $ gunzip < a.gz
  this is a test
  $ cat not.gz
  this is a test

check hg cat operation

  $ hg cat a.gz
  this is a test
  $ hg cat --decode a.gz | gunzip
  this is a test
  $ mkdir subdir
  $ cd subdir
  $ hg -R .. cat ../a.gz
  this is a test
  $ hg -R .. cat --decode ../a.gz | gunzip
  this is a test

  $ cd ..
