encoding: avoid quadratic time complexity when json-encoding non-UTF8 strings

Apparently the code uses "+=" with a bytes object, which is linear-time, so the
whole encoding is quadratic-time. This patch makes us use a bytearray object,
instead, which has a(n amortized-)constant-time append operation.

The encoding is still not particularly fast, but at least a 10MB file
takes tens of seconds, not many hours to encode.

Test template keywords
======================

  $ hg init a
  $ cd a
  $ echo a > a
  $ hg add a
  $ echo line 1 > b
  $ echo line 2 >> b
  $ hg commit -l b -d '1000000 0' -u 'User Name <user@hostname>'

  $ hg add b
  $ echo other 1 > c
  $ echo other 2 >> c
  $ echo >> c
  $ echo other 3 >> c
  $ hg commit -l c -d '1100000 0' -u 'A. N. Other <other@place>'

  $ hg add c
  $ hg commit -m 'no person' -d '1200000 0' -u 'other@place'
  $ echo c >> c
  $ hg commit -m 'no user, no domain' -d '1300000 0' -u 'person'

  $ echo foo > .hg/branch
  $ hg commit -m 'new branch' -d '1400000 0' -u 'person'

  $ hg co -q 3
  $ echo other 4 >> d
  $ hg add d
  $ hg commit -m 'new head' -d '1500000 0' -u 'person'

  $ hg merge -q foo
  $ hg commit -m 'merge' -d '1500001 0' -u 'person'

Second branch starting at nullrev:

  $ hg update null
  0 files updated, 0 files merged, 4 files removed, 0 files unresolved
  $ echo second > second
  $ hg add second
  $ hg commit -m second -d '1000000 0' -u 'User Name <user@hostname>'
  created new head

  $ echo third > third
  $ hg add third
  $ hg mv second fourth
  $ hg commit -m third -d "2020-01-01 10:01"

Working-directory revision has special identifiers, though they are still
experimental:

  $ hg log -r 'wdir()' -T '{rev}:{node}\n'
  2147483647:ffffffffffffffffffffffffffffffffffffffff

  $ hg log -r 'wdir()' -Tjson --debug
  [
   {
    "added": [],
    "bookmarks": [],
    "branch": "default",
    "date": [0, 0],
    "desc": "",
    "extra": {"branch": "default"},
    "manifest": "ffffffffffffffffffffffffffffffffffffffff",
    "modified": [],
    "node": "ffffffffffffffffffffffffffffffffffffffff",

    "phase": "draft",
    "removed": [],
    "rev": 2147483647,
    "tags": [],
    "user": "test"
   }
  ]

  $ hg log -r 'wdir()' -T '{manifest}\n'
  2147483647:ffffffffffff

However, for negrev, we refuse to output anything (as well as for null)

  $ hg log -r 'wdir() + null' -T 'bla{negrev}nk\n'
  blank
  blank

Changectx-derived keywords are disabled within {manifest} as {node} changes:

  $ hg log -r0 -T 'outer:{p1node} {manifest % "inner:{p1node}"}\n'
  outer:0000000000000000000000000000000000000000 inner:

Check that {phase} works correctly on parents:

  $ cat << EOF > parentphase
  > changeset_debug = '{rev} ({phase}):{parents}\n'
  > parent = ' {rev} ({phase})'
  > EOF
  $ hg phase -r 5 --public
  $ hg phase -r 7 --secret --force
  $ hg log --debug -G --style ./parentphase

Test 'graphwidth' in 'hg log' on various topologies. The key here is that the
printed graphwidths 3, 5, 7, etc. should all line up in their respective
columns. We don't care about other aspects of the graph rendering here.

  $ hg init graphwidth
  $ cd graphwidth

  $ wrappabletext="a a a a a a a a a a a a"

  $ printf "first\n" > file
  $ hg add file
  $ hg commit -m "$wrappabletext"

  $ printf "first\nsecond\n" > file
  $ hg commit -m "$wrappabletext"

  $ hg checkout 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ printf "third\nfirst\n" > file
  $ hg commit -m "$wrappabletext"

The point of graphwidth is to allow wrapping that accounts for the space taken
by the graph.

  $ COLUMNS=10 hg log --graph -T "{fill(desc, termwidth - graphwidth)}"

  |  a a a a
  |  a a a a

Something tricky happens when there are elided nodes; the next drawn row of
edges can be more than one column wider, but the graph width only increases by
one column. The remaining columns are added in between the nodes.

  $ hg log --graph -T "{graphwidth}" -r "0|2|4|5"
  o    5
  |\
  | \
  | :\
  o : :  7
  :/ /
  : o  5
  :/
  o  3
