Summary:
The dynamicconfig logic had an assert checking that a config was not
added by the dynamicconfig twice. This isn't actually a valid assert since the
caller could load the config as many times as it wanted.
This happened in hg doctor, where it loaded the ui once manually (without a repo
object) then it loaded it again during the creation of the repo object. I went
ahead and cleaned up hg doctor to not do this, but let's get rid of the assert
anyway.

Any native code (C/C++/Rust) that Mercurial (either core or extensions)
depends on should go here. Python code, or native code that depends on
Python code (e.g. #include <Python.h> or use cpython) is disallowed.
As we start to convert more of Mercurial into Rust, and write new paths
entrirely in native code, we'll want to limit our dependency on Python, which is
why this barrier exists.
See also hgext/extlib/README.md, mercurial/cext/README.mb.
How do I choose between lib and extlib (and cext)?
If your code is native and doesn't depend on Python (awesome!), it goes here.
Otherwise, put it in hgext/extlib (if it's only used by extensions) or
mercurial/cext (if it's used by extensions or core).
