topic: properly decode topic and topic namespace after reading from disk

Looks like we forgot that the bytes read from disk should be converted to the
local encoding. The way it's done in this patch is how branch is handled in
core.

  $ . "$TESTDIR/testlib/topic_setup.sh"

  $ hg init repo
  $ cd repo

Setting a topic namespace alone doesn't affect wdir()

  $ hg debug-topic-namespace space-name
  marked working directory as topic namespace: space-name
  $ hg debug-topic-namespaces
  space-name

  $ hg log -r 'wdir()' -T '{topic_namespace}\n'
  none

  $ hg log -r 'wdir()' -T '{fqbn}\n'
  default

But after setting a topic the already-set namespace is visible on wdir()

  $ hg topic feature
  marked working directory as topic: feature
  $ hg topics
   * feature (0 changesets)

  $ hg log -r 'wdir()' -T '{topic_namespace}\n'
  space-name

  $ hg log -r 'wdir()' -T '{fqbn}\n'
  default//space-name/feature

Non-ascii topic namespace name

  $ hg debug-topic-namespace --clear
  $ hg --encoding utf-8 debug-topic-namespace æ
  marked working directory as topic namespace: \xc3\xa6 (esc)
  $ hg --encoding utf-8 debug-topic-namespaces
  æ (esc)
  $ hg --encoding ascii debug-topic-namespaces
  ? (esc)
  $ hg --encoding latin1 debug-topic-namespaces
  \xe6 (esc)

  $ hg branches

  $ hg debug-topic-namespace --clear
  $ hg debug-topic-namespaces

  $ hg topic --clear
  clearing empty topic "feature"
  $ hg topics

  $ hg debugtopicnamespace --clear nonsense
  abort: cannot use --clear when setting a topic namespace
  [255]

  $ hg branch stable
  marked working directory as branch stable
  (branches are permanent and global, did you want a bookmark?)
  $ hg debug-topic-namespace alice
  marked working directory as topic namespace: alice
  $ hg topic feature
  marked working directory as topic: feature
  $ echo a > a
  $ hg ci -qAm a

  $ hg debug-topic-namespaces
  alice

  $ hg log -r . -T '{rev}: {branch} {topic_namespace} {topic}\n'
  0: stable alice feature

  $ hg log -r . -T '{rev}: {fqbn}\n'
  0: stable//alice/feature

  $ hg branches

Updating to a revision with a namespace should activate it

  $ hg up null
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg debug-topic-namespace
  none
  $ hg topics
     feature (1 changesets)
  $ hg up 0
  switching to topic-namespace alice
  switching to topic feature
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg debug-topic-namespace
  alice
  $ hg topics
   * feature (1 changesets)

Updating to a topic namespace is not supported

  $ hg up alice
  abort: unknown revision 'alice'

Parsing

  $ hg debugparsefqbn foo/bar//user26/feature -T '[{branch}] <{topic_namespace}> ({topic})\n'
  [foo/bar] <user26> (feature)

no double slashes means it's a named branch
  $ hg debug-parse-fqbn foo/bar
  branch:    foo/bar
  namespace: none
  topic:     

Formatting

  $ hg debugformatfqbn -b branch -n namespace -t topic
  branch//namespace/topic

  $ hg debug-format-fqbn -n namespace
  //namespace/

  $ hg debug-format-fqbn -b foo/bar -n user26 -t feature
  foo/bar//user26/feature

default values

  $ hg debug-format-fqbn -b default -n none -t '' --no-short
  default//none/
  $ hg debug-format-fqbn -b default -n none -t '' --short
  default

  $ hg debug-format-fqbn -b default -n namespace -t '' --no-short
