convert: use None value for missing files instead of overloading IOError

The internal API used IOError to indicate that a file should be marked as
removed.

There is some correlation between IOError (especially with ENOENT) and files
that should be removed, but using IOErrors to represent file removal internally
required some hacks.

Instead, use the value None to indicate that the file not is present.

Before, spurious IO errors could cause commits that silently removed files.
They will now be reported like all other IO errors so the root cause can be
fixed.

  $ hg init repo1

  $ mkdir a b a/1 b/1 b/2
  $ touch in_root a/in_a b/in_b a/1/in_a_1 b/1/in_b_1 b/2/in_b_2

hg status in repo root:

combining patterns with root and patterns without a root works

  $ hg st a/in_a re:.*b$
  ? a/in_a

Run status with 2 different flags.
Check if result is the same or different.
If result is not as expected, raise error

  $ assert() {
  >     hg status $1 > ../a
  >     hg status $2 > ../b
  >     if diff ../a ../b > /dev/null; then
  >         out=0
  >     else
  >         out=1
  >     fi
  >     if [ $3 -eq 0 ]; then
  >         df="same"
  >     else
  >         df="different"
  >     fi
  >     if [ $out -ne $3 ]; then
  >         echo "Error on $1 and $2, should be $df."
  >     fi

hg status of binary file starting with '\1\n', a separator for metadata:

  $ hg status -A

test "hg status" with "directory pattern" which matches against files
only known on target revision.

  $ hg init repo6
  $ cd repo6

  $ echo a > a.txt
  $ hg add a.txt
  $ hg commit -m '#0'
  $ mkdir -p 1/2/3/4/5
  $ echo b > 1/2/3/4/5/b.txt
  $ hg add 1/2/3/4/5/b.txt
  $ hg commit -m '#1'

  $ hg update -C 0 > /dev/null
  $ hg status -A
  C a.txt

the directory matching against specified pattern should be removed,
because directory existence prevents 'dirstate.walk()' from showing
warning message about such pattern.

  $ test ! -d 1
  $ hg status -A --rev 1 1/2/3/4/5/b.txt

  $ hg status -A --rev 1 1/2/3
