localrepo: iteratively derive local repository type

This commit implements the dynamic local repository type derivation
that was explained in the recent commit
bfeab472e3c0 "localrepo: create new function for instantiating a local
repo object."

Instead of a static localrepository class/type which must be customized
after construction, we now dynamically construct a type by building up
base classes/types to represent specific repository interfaces.

Conceptually, the end state is similar to what was happening when
various extensions would monkeypatch the __class__ of newly-constructed
repo instances. However, the approach is inverted. Instead of making
the instance then customizing it, we do the customization up front
by influencing the behavior of the type then we instantiate that
custom type.

This approach gives us much more flexibility. For example, we can
use completely separate classes for implementing different aspects
of the repository. For example, we could have one class representing
revlog-based file storage and another representing non-revlog based
file storage. When then choose which implementation to use based on
the presence of repo requirements.

A concern with this approach is that it creates a lot more types
and complexity and that complexity adds overhead. Yes, it is true that
this approach will result in more types being created. Yes, this is
more complicated than traditional "instantiate a static type." However,
I believe the alternatives to supporting alternate storage backends
are just as complicated. (Before I arrived at this solution, I had
patches storing factory functions on local repo instances for e.g.
constructing a file storage instance. We ended up having a handful
of these. And this was logically identical to assigning custom
methods. Since we were logically changing the type of the instance,
I figured it would be better to just use specialized types instead
of introducing levels of abstraction at run-time.)

On the performance front, I don't believe that having N base classes
has any significant performance overhead compared to just a single base
class. Intuition says that Python will need to iterate the base classes
to find an attribute. However, CPython caches method lookups: as long as
the __class__ or MRO isn't changing, method attribute lookup should be
constant time after first access. And non-method attributes are stored
in __dict__, of which there is only 1 per object, so the number of
base classes for __dict__ is irrelevant.

Anyway, this commit splits up the monolithic completelocalrepository
interface into sub-interfaces: 1 for file storage and 1 representing
everything else.

We've taught ``makelocalrepository()`` to call a series of factory
functions which will produce types implementing specific interfaces.
It then calls type() to create a new type from the built-up list of
base types.

This commit should be considered a start and not the end state. I
suspect we'll hit a number of problems as we start to implement
alternate storage backends:

* Passing custom arguments to __init__ and setting custom attributes
  on __dict__.
* Customizing the set of interfaces that are needed. e.g. the
  "readonly" intent could translate to not requesting an interface
  providing methods related to writing.
* More ergonomic way for extensions to insert themselves so their
  callbacks aren't unconditionally called.
* Wanting to modify vfs instances, other arguments passed to __init__.

That being said, this code is usable in its current state and I'm
convinced future commits will demonstrate the value in this approach.

Test template map files and styles
==================================

  $ 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"

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"
  > EOF

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

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
  > %include $HGRCPATH
  > %include map-simple
  > [templates]
  > foo = "{changeset}"
  > EOF
  $ HGRCPATH=./myhgrc hg log -l1 -Tfoo
  8
  $ HGRCPATH=./myhgrc hg log -l1 -T'{a}\n'
  8

Test template map inheritance

  $ echo "__base__ = map-cmdline.default" > map-simple
  $ printf 'cset = "changeset: ***{rev}***\\n"\n' >> map-simple
  $ hg log -l1 -T./map-simple
  changeset: ***8***
  tag:         tip
  user:        test
  date:        Wed Jan 01 10:01:00 2020 +0000
  summary:     third
  

Test docheader, docfooter and separator in template map

  $ cat <<'EOF' > map-myjson
  > docheader = '\{\n'
  > docfooter = '\n}\n'
  > separator = ',\n'
  > changeset = ' {dict(rev, node|short)|json}'
  > EOF
  $ hg log -l2 -T./map-myjson
  {
   {"node": "95c24699272e", "rev": 8},
   {"node": "29114dbae42b", "rev": 7}
  }

Test docheader, docfooter and separator in [templates] section

  $ cat <<'EOF' >> .hg/hgrc
  > [templates]
  > myjson = ' {dict(rev, node|short)|json}'
  > myjson:docheader = '\{\n'
  > myjson:docfooter = '\n}\n'
  > myjson:separator = ',\n'
  > :docheader = 'should not be selected as a docheader for literal templates\n'
  > EOF
  $ hg log -l2 -Tmyjson
  {
   {"node": "95c24699272e", "rev": 8},
   {"node": "29114dbae42b", "rev": 7}
  }
  $ hg log -l1 -T'{rev}\n'
  8

Template should precede style option

  $ hg log -l1 --style default -T '{rev}\n'
  8

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

  $ echo c >> c
  $ hg add c
  $ hg commit -qm ' '

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
  $ diff -U 0 log.out phases.out | egrep -v '^---|^\+\+\+|^@@'
  +phase:       draft

  $ hg log -v > log.out
  $ hg log -v --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out
  $ hg log -v -T phases > phases.out
  $ diff -U 0 log.out phases.out | egrep -v '^---|^\+\+\+|^@@'

  $ hg log -q > log.out
  $ hg log -q --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out
  $ hg log -q -T phases > phases.out
  $ cmp log.out phases.out || diff -u log.out phases.out

  $ hg log --debug > log.out
  $ hg log --debug --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.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
  $ hg --color=debug log --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out
  $ hg --color=debug log -T phases > phases.out
  $ diff -U 0 log.out phases.out | egrep -v '^---|^\+\+\+|^@@'

Remove commit with empty commit message, so as to not pollute further
tests.

  $ hg --config extensions.strip= strip -q .

Revision with no copies (used to print a traceback):

  $ hg tip -v --template '\n'
  

Compact style works:

Add a dummy commit to make up for the instability of the above:

  $ echo a > a
  $ hg add a
  $ hg ci -m future

Add a commit that does all possible modifications at once

  $ echo modify >> third
  $ touch b
  $ hg add b
  $ hg mv fourth fifth
  $ hg rm a
  $ hg ci -m "Modify, add, remove, rename"
