rebase: remove some redundant setting of dirstate parents
Since we're now setting the dirstate parents to its correct values
from the beginning (right after `merge.update()`), we usually don't
need to set them again before committing. The only case we need to
care about is when committing collapsed commits. So we can remove the

rebase: don't use rebased node as dirstate p2 (BC)
When rebasing a node, we currently use the rebased node as p2 in the
dirstate until just before we commit it (we then change to the desired
parents). This p2 is visible to the user when the rebase gets
interrupted because of merge conflicts. That can be useful to the user
as a reminder of which commit is currently being rebased, but I
believe it's incorrect for a few reasons:
* I think the dirstate parents should be the ones that will be set
when the commit is created.
* I think having two parents means that you're merging those two
commits, but when rebasing, you're generally grafting, not merging.
* When rebasing a merge commit, we should use the two desired parents
as dirstate parents (and we clearly can't have the rebased node as
a third dirstate parent).
* `hg graft` (and `hg update --merge`) sets only one parent and `hg
rebase` should be consistent with that.
I realize that this is a somewhat large user-visible change, but I
think it's worth it because it will simplify things quite a bit.

rebase: stop relying on having two parents to resume rebase
I'm about to make it so we don't have two parents when a rebase is
interrupted (unless we're just rebasing on a merge commit). The code
for detecting if we're resuming a rebase relied on having two parents,
so this patch rewrites that to instead set a boolean when we resume.
Note that `self.resume` in the new condition implies `not
self.inmemory` (rebase cannot be resumed in memory), so that's why
that part can be omitted.

rebase: always be graft-like, not merge-like, also for merges
Rebase works by updating to a commit and then grafting changes on
top. However, before this patch, it would actually merge in changes
instead of grafting them in in some cases. That is, it would use the
common ancestor as base instead of using one of the parents. That
seems wrong to me, so I'm changing it so `defineparents()` always
returns a value for `base`.
This fixes the bad behavior in test-rebase-newancestor.t, which was
introduced in
65f215ea3e8e (tests: add test for rebasing merges with
ancestors of the rebase destination, 2014-11-30).
The difference in test-rebase-dest.t is because the files in the tip
revision were A, D, E, F before this patch and A, D, F, G after it. I
think both files should ideally be there.

rust-dirstatemap: add `NonNormalEntries` class
This fix introduces the same encapsulation as the `copymap`. There is no easy
way of doing this any better for now.

Pretty brutal regression!

help: add a mechanism to change flags' help depending on config
It seems reasonable to have a similar mechanism for the rest of the
help, but no such thing is implemented.
The goal is to make the help of commands clearer in the presence of
significant default changes, like tweakdefaults or with company-wide
hgrcs. In these cases, a user looking at the help of a command doesn't
exactly know what his hgrc is doing.
Apply to this to the --git option of commands that display diffs, as
this option in particular causes confusion for some reason.

lfs: use str for the open() mode when opening a blob for py3
The other fix for this was to leave the mode as bytes, and import
`pycompat.open()` like a bunch of other modules do. But I think it's confusing
to still use bytes at the python boundary, and obviously error prone. Grepping
for ` open\(.+, ['"][a-z]+['"]\)` and ` open\(.+, b['"][a-z]+['"]\)` outside of
`tests`, there are 51 and 87 uses respectively, so it's not like this is a rare
direct usage.

rust-dirstatemap: cache non normal and other parent set
Performance of `hg update` was significantly worse since the introduction of
the Rust `dirstatemap`. This regression was noticed by Valentin Gatien-Baron
when working on a large repository, as it goes unnoticed for smaller
repositories like Mercurial itself.
This fix introduces the same getter/setter mechanism at `hg-core` level as
for `set/get_dirs`.
While this technique is, as previously discussed, quite suboptimal, it fixes an
important enough problem. Refactoring `hg-core` to use the typestate
pattern could be a good approach to improving code quality in a future patch.
