Summary:
D13853115 adds `edenscm/` to `sys.path` and code still uses `import mercurial`.
That has nasty problems if both `import mercurial` and
`import edenscm.mercurial` are used, because Python would think `mercurial.foo`
and `edenscm.mercurial.foo` are different modules so code like
`try: ... except mercurial.error.Foo: ...`, or `isinstance(x, mercurial.foo.Bar)`
would fail to handle the `edenscm.mercurial` version. There are also some
module-level states (ex. `extensions._extensions`) that would cause trouble if
they have multiple versions in a single process.
Change imports to use the `edenscm` so ideally the `mercurial` is no longer
imported at all. Add checks in extensions.py to catch unexpected extensions
importing modules from the old (wrong) locations when running tests.

Summary: This would lead to less surprises than using the default priority.

Summary:
Migrate builtin namespace definition to use the registrar. So we can deprecate
`addnamespace`.
`after` is not expressive enough in certain cases, although it's easier to
understand. Add a `priority` parameter for more explicit ordering handling.

Summary:
Previously, there is no easy API to add a namespace with desired order. There
is `extensions.afterloaded`, but that only works for `ui/extsetup`, not for
`reposetup`.
This diff add a namespace predicate so registering a namespace is similar to
registering a revset. It also provides an optional `after` parameter to define
the desired order, like:
from mercurial import registrar, namespaces
namespacepredicate = registrar.namespacepredicate()
namespacepredicate("svn", after=["remotenames"])
def svn(repo):
return namespaces.namespace("svn", ...)
Existing namespaces will be migrated by upcoming changes.
This is useful for things wanting to resolve custom names, like globalrevs and
commit cloud.
