formatter: populate ctx from repo and node value

This will basically replace the fm.contexthint() API. I originally thought
this would be too complicated, and I wrote 8399438bc7ef "formatter: provide
hint of context keys required by template" because of that. However, I had
to add a similar mechanism for fctx templates, and the overall machinery
became way simpler than my original patch.

The test output slightly changed as {author} is no longer available in
the {manifest} context, which isn't the point this test targeted on.

 """Generic output formatting for Mercurial
 
 The formatter provides API to show data in various ways. The following
 functions should be used in place of ui.write():
 
 - fm.write() for unconditional output
 - fm.condwrite() to show some extra data conditionally in plain output
 - fm.context() to provide changectx to template output
 - fm.data() to provide extra data to JSON or template output
 - fm.plain() to show raw text that isn't provided to JSON or template output
 
 To show structured data (e.g. date tuples, dicts, lists), apply fm.format*()
 beforehand so the data is converted to the appropriate data type. Use
 fm.isplain() if you need to convert or format data conditionally which isn't
 supported by the formatter API.
 
 To build nested structure (i.e. a list of dicts), use fm.nested().
 
 See also https://www.mercurial-scm.org/wiki/GenericTemplatingPlan
 
 fm.condwrite() vs 'if cond:':
 
 In most cases, use fm.condwrite() so users can selectively show the data
 in template output. If it's costly to build data, use plain 'if cond:' with
 fm.write().
 
 fm.nested() vs fm.formatdict() (or fm.formatlist()):
 
 fm.nested() should be used to form a tree structure (a list of dicts of
 lists of dicts...) which can be accessed through template keywords, e.g.
 "{foo % "{bar % {...}} {baz % {...}}"}". On the other hand, fm.formatdict()
 exports a dict-type object to template, which can be accessed by e.g.
 "{get(foo, key)}" function.
 
 Doctest helper:
 
 >>> def show(fn, verbose=False, **opts):
 ...     import sys
 ...     from . import ui as uimod
 ...     ui = uimod.ui()
 ...     ui.verbose = verbose
 ...     ui.pushbuffer()
 ...     try:
 ...         return fn(ui, ui.formatter(pycompat.sysbytes(fn.__name__),
 ...                   pycompat.byteskwargs(opts)))
 ...     finally:
 ...         print(pycompat.sysstr(ui.popbuffer()), end='')
 
 Basic example:
 
 >>> def files(ui, fm):
 ...     files = [(b'foo', 123, (0, 0)), (b'bar', 456, (1, 0))]
 ...     for f in files:
 ...         fm.startitem()
 ...         fm.write(b'path', b'%s', f[0])
 ...         fm.condwrite(ui.verbose, b'date', b'  %s',
 ...                      fm.formatdate(f[2], b'%Y-%m-%d %H:%M:%S'))
 ...         fm.data(size=f[1])
 ...         fm.plain(b'\\n')
 ...     fm.end()
 >>> show(files)
 foo
 bar
 >>> show(files, verbose=True)
 foo  1970-01-01 00:00:00
 bar  1970-01-01 00:00:01
 >>> show(files, template=b'json')
 [
  {
   "date": [0, 0],
   "path": "foo",
   "size": 123
  },
  {
   "date": [1, 0],
   "path": "bar",
   "size": 456
  }
 ]
 >>> show(files, template=b'path: {path}\\ndate: {date|rfc3339date}\\n')
 path: foo
 date: 1970-01-01T00:00:00+00:00
 path: bar
 date: 1970-01-01T00:00:01+00:00
 
 Nested example:
 
 >>> def subrepos(ui, fm):
 ...     fm.startitem()
 ...     fm.write(b'reponame', b'[%s]\\n', b'baz')
 ...     files(ui, fm.nested(b'files', tmpl=b'{reponame}'))
 ...     fm.end()
 >>> show(subrepos)
 [baz]
 foo
 bar
 >>> show(subrepos, template=b'{reponame}: {join(files % "{path}", ", ")}\\n')
 baz: foo, bar

 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
 
 Some keywords are invalid for working-directory revision, but they should
 never cause crash:
 
   $ hg log -r 'wdir()' -T '{manifest}\n'
   
 
+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.

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

 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.

 Make sure user/global hgrc does not affect tests
 
   $ echo '[ui]' > .hg/hgrc
   $ echo 'logtemplate =' >> .hg/hgrc
   $ echo 'style =' >> .hg/hgrc
 
 Add some simple styles to settings
 
   $ cat <<'EOF' >> .hg/hgrc
   > [templates]
   > simple = "{rev}\n"
   > simple2 = {rev}\n
   > rev = "should not precede {rev} keyword\n"

   $ hg log -l1 -Tsimple

   $ hg log -l1 -Tsimple2
   8
   $ hg log -l1 -Trev
   should not precede 8 keyword
   $ hg log -l1 -T '{simple}'

 Map file shouldn't see user templates:
 
   $ cat <<EOF > tmpl
   > changeset = 'nothing expanded:{simple}\n'
   > EOF
   $ hg log -l1 --style ./tmpl
   nothing expanded:
 
 Test templates and style maps in files:
 
   $ echo "{rev}" > tmpl
   $ hg log -l1 -T./tmpl
   8
   $ hg log -l1 -Tblah/blah
   blah/blah (no-eol)
 
   $ printf 'changeset = "{rev}\\n"\n' > map-simple
   $ hg log -l1 -T./map-simple
   8
 
  a map file may have [templates] and [templatealias] sections:
 
   $ cat <<'EOF' > map-simple
   > [templates]
   > changeset = "{a}\n"
   > [templatealias]
   > a = rev
   > EOF
   $ hg log -l1 -T./map-simple
   8
 
  so it can be included in hgrc
 
   $ cat <<EOF > myhgrc

 Add a commit with empty description, to ensure that the templates
 below will omit the description line.

 Default style is like normal output. Phases style should be the same
 as default style, except for extra phase lines.
 
   $ hg log > log.out
   $ hg log --style default > style.out
   $ cmp log.out style.out || diff -u log.out style.out
   $ hg log -T phases > phases.out

   $ hg log --debug -T phases > phases.out
   $ cmp log.out phases.out || diff -u log.out phases.out
 
 Default style of working-directory revision should also be the same (but
 date may change while running tests):
 
   $ hg log -r 'wdir()' | sed 's|^date:.*|date:|' > log.out
   $ hg log -r 'wdir()' --style default | sed 's|^date:.*|date:|' > style.out
   $ cmp log.out style.out || diff -u log.out style.out
 
   $ hg log -r 'wdir()' -v | sed 's|^date:.*|date:|' > log.out
   $ hg log -r 'wdir()' -v --style default | sed 's|^date:.*|date:|' > style.out
   $ cmp log.out style.out || diff -u log.out style.out
 
   $ hg log -r 'wdir()' -q > log.out
   $ hg log -r 'wdir()' -q --style default > style.out
   $ cmp log.out style.out || diff -u log.out style.out
 
   $ hg log -r 'wdir()' --debug | sed 's|^date:.*|date:|' > log.out
   $ hg log -r 'wdir()' --debug --style default \
   > | sed 's|^date:.*|date:|' > style.out
   $ cmp log.out style.out || diff -u log.out style.out
 
 Default style should also preserve color information (issue2866):
 
   $ cp $HGRCPATH $HGRCPATH-bak
   $ cat <<EOF >> $HGRCPATH
   > [extensions]
   > color=
   > EOF
 
   $ hg --color=debug log > log.out
