resourceutil: account for the non-resource-like file hierarchy under py2exe...
resourceutil: account for the non-resource-like file hierarchy under py2exe After 9e367157a990, config files for py2exe were expected to be in C:\Program Files\Mercurial\mercurial\defaultrc because of the implied resource structure of 'mercurial.defaultrc.*.rc', relative to the executable. Accomodating this would require changes to the WIX and Inno scripts (and perhaps the script that generates the WIX script), as well as 3rd party bundlers like TortoiseHg. But these files aren't read as resources anyway- they fall back to the filesystem APIs. (If we really wanted to carry on the charade, the installer would have to also sprinkle various empty __init__.py files around.) Instead, this simply prunes the 'mercurial.' portion of the resource name when run with py2exe. (PyOxidizer uses the resources API, not the filesystem fallback, so it is unaffected.) Since this hack only affects the py2 Windows installers and is less risky, I think it's reasonable. We haven't needed to load any 3rd party resource up to this point, and would have to make packaging changes anyway to handle that. Differential Revision: https://phab.mercurial-scm.org/D8058

// This object needs to share references to multiple members of its Rust
// inner struct, namely `copy_map`, `dirs` and `all_dirs`.
// Right now `CopyMap` is done, but it needs to have an explicit reference
// to `RustDirstateMap` which itself needs to have an encapsulation for
// every method in `CopyMap` (copymapcopy, etc.).
// This is ugly and hard to maintain.
// The same logic applies to `dirs` and `all_dirs`, however the `Dirs`
// `py_class!` is already implemented and does not mention
// `RustDirstateMap`, rightfully so.
// All attributes also have to have a separate refcount data attribute for
// leaks, with all methods that go along for reference sharing.
