hg: show the correct message when cloning an LFS repo with extension disabled

The `extensions._disabledpaths()` doesn't handle fetching help from `__index__`,
so it returns an empty dictionary of paths.  That means None is always returned
from `extensions.disabled_help()` when embedding resources inside the pyoxidizer
or py2exe binary, regardless of the arg or if is an external extension stored in
the filesystem.  And that means wrongly telling the user with an explicitly
disabled LFS extension that it will be enabled locally upon cloning from an LFS
remote.  That causes test-lfs-serve.t:295 to fail.

This effectively reverts most of the rest of 843418dc0b1b, while keeping the
help text change in place (which was specifically identified as a problem).

Test support for partial-resolution tools

Create a tool that resolves conflicts after line 5 by simply dropping those
lines (even if there are no conflicts there)
  $ cat >> "$TESTTMP/head.sh" <<'EOF'
  > #!/bin/sh
  > for f in "$@"; do
  >   head -5 $f > tmp
  >   mv -f tmp $f
  > done
  > EOF
  $ chmod +x "$TESTTMP/head.sh"
...and another tool that keeps only the last 5 lines instead of the first 5.
  $ cat >> "$TESTTMP/tail.sh" <<'EOF'
  > #!/bin/sh
  > for f in "$@"; do
  >   tail -5 $f > tmp
  >   mv -f tmp $f
  > done
  > EOF
  $ chmod +x "$TESTTMP/tail.sh"

Set up both tools to run on all patterns (the default), and let the `tail` tool
run after the `head` tool, which means it will have no effect (we'll override it
to test order later)
  $ cat >> "$HGRCPATH" <<EOF
  > [partial-merge-tools]
  > head.executable=$TESTTMP/head.sh
  > tail.executable=$TESTTMP/tail.sh
  > tail.order=1
  > EOF

  $ make_commit() {
  >   echo "$@" | xargs -n1 > file
  >   hg add file 2> /dev/null
  >   hg ci -m "$*"
  > }


Let a partial-resolution tool resolve some conflicts and leave other conflicts
for the regular merge tool (:merge3 here)

  $ hg init repo
  $ cd repo
  $ make_commit a b c d e f
  $ make_commit a b2 c d e f2
  $ hg up 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ make_commit a b3 c d e f3
  created new head
  $ hg merge 1 -t :merge3
  merging file
  warning: conflicts while merging file! (edit, then use 'hg resolve --mark')
  0 files updated, 0 files merged, 0 files removed, 1 files unresolved
  use 'hg resolve' to retry unresolved file merges or 'hg merge --abort' to abandon

  $ cat file

With premerge=keep, the partial-resolution tools runs before and doesn't see
the conflict markers

  $ hg up -C 2
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cat >> .hg/hgrc <<EOF
  > [merge-tools]
  > my-local.executable = cat
  > my-local.args = $local
  > my-local.premerge = keep-merge3
  > EOF
  $ hg merge 1 -t my-local
  merging file
  0 files updated, 1 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ cat file

When a partial-resolution tool resolves all conflicts, the resolution should
be recorded and the regular merge tool should not be invoked for the file.

  $ hg up -C 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ make_commit a b c d e f2
  created new head
  $ hg up 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ make_commit a b c d e f3
  created new head
  $ hg merge 3 -t false
  merging file
  0 files updated, 1 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ cat file
  a
  b

Can disable all partial merge tools (the `head` tool would have resolved this
conflict it had been enabled)

  $ hg up -C 4

  $ hg merge 3 -t :merge3 --config merge.disable-partial-tools=yes
  merging file
  warning: conflicts while merging file! (edit, then use 'hg resolve --mark')

Can disable one partial merge tool (the `head` tool would have resolved this
conflict it had been enabled)

  $ hg up -C 4
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg merge 3 -t :merge3 --config partial-merge-tools.head.disable=yes
  merging file
  warning: conflicts while merging file! (edit, then use 'hg resolve --mark')

Only tools whose patterns match are run. We make `head` not match here, so
only `tail` should run

  $ hg up -C 4
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg merge 3 -t :merge3 --config partial-merge-tools.head.patterns=other
  merging file
  warning: conflicts while merging file! (edit, then use 'hg resolve --mark')

  >>>>>>> merge rev:       8c217da987be - test: a b c d e f2


If there are several matching tools, they are run in requested order. We move
`head` after `tail` in order here so it has no effect (the conflict in "f" thus
remains).

  $ hg up -C 4
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg merge 3 -t :merge3 --config partial-merge-tools.head.order=2
  merging file
  warning: conflicts while merging file! (edit, then use 'hg resolve --mark')

When using "nomerge" tools (e.g. `:other`), the partial-resolution tools
should not be run.

  $ hg up -C 4
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg merge 3 -t :other
  0 files updated, 1 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ cat file
  a
  b
  c
  d
  e
  f2


If a partial-resolution tool resolved some conflict and simplemerge can
merge the rest, then the regular merge tool should not be used. Here we merge
"a b c d e3 f3" with "a b2 c d e f2". The `head` tool resolves the conflict in
"f" and the internal simplemerge merges the remaining changes in "b" and "e".

  $ hg up -C 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ make_commit a b c d e3 f3
  created new head
  $ hg merge 1 -t false
  merging file
  0 files updated, 1 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ cat file
  a
  b2

  e3
