packaging: stop installing Contributors.txt This file isn't up to date. If we are going to call out contributors, we should auto generate a file from `hg log` or something. I don't think we need to include it in the Windows install. This change makes Inno more consistent with WiX, which doesn't ship this file. Differential Revision: https://phab.mercurial-scm.org/D7170

packaging: remove hg-ssh.8.html from Inno installer We don't ship hg-ssh because it requires a python.exe to run, which we don't ship. So it doesn't make sense to ship the HTML documentation for this tool. This change makes the Inno install layout more consistent with WiX, which doesn't ship this file. Functionality for removing files has been made generic, in anticipation of future expansion. Differential Revision: https://phab.mercurial-scm.org/D7169

packaging: install .rc files to hgrc.d Currently, Inno installs these .rc files to a default.d directory and WiX to a hgrc.d directory. Mercurial automatically loads files in an hgrc.d directory next to the executable and in an "internal" default.d directory. This "internal" directory is util.datadir, which on Windows installs made with py2exe is the directory containing hg.exe. So on Windows both hgrc.d and default.d directories relative to hg.exe are loaded. For the install layout, I think it makes sense for hgrc.d to be used, as that path is documented as non-internal. So this commit changes the Inno install layout to use hgrc.d instead of default.d. .. bc:: Changed default config file location in Windows .exe installers Mercurial's installer installs some default .rc config files. Previously, these were installed in a default.d directory. These are now installed in an hgrc.d directory. Custom default.d/*.rc files should still be loaded. But it is recommended to move these to hgrc.d/*.rc. This change only affects the .exe installers (not the .msi installers). Differential Revision: https://phab.mercurial-scm.org/D7168

rust: introduce SIZE_FROM_OTHER_PARENT constant This will clarify what `-2` meant in the codebase. This change also merged imports in affected files for cleanup. Differential Revision: https://phab.mercurial-scm.org/D7301

rust-status: refactor dispatch case for normal files This should make the code easier to read and more idiomatic. Differential Revision: https://phab.mercurial-scm.org/D7300

rust-status: return a ParallelIterator instead of a Vec from stat_dmap_entries This allows the caller function to choose when and how the iteration and/or collection happens. This change also cleans up the now unused `filter_map`. Differential Revision: https://phab.mercurial-scm.org/D7299
