[PATCH 00/18] Support symbolic links on Windows

This finally upstreams Git for Windows' support for Windows' branch of symbolic links, which has been maturing since 2015. It is based off of js/prep-symlink-windows.

Bill Zissimopoulos (1):
  mingw: compute the correct size for symlinks in `mingw_lstat()`

Johannes Schindelin (3):
  mingw: try to create symlinks without elevated permissions
  mingw: emulate `stat()` a little more faithfully
  mingw: special-case index entries for symlinks with buggy size

Karsten Blees (14):
  mingw: don't call `GetFileAttributes()` twice in `mingw_lstat()`
  mingw: implement `stat()` with symlink support
  mingw: drop the separate `do_lstat()` function
  mingw: let `mingw_lstat()` error early upon problems with reparse
    points
  mingw: teach dirent about symlinks
  mingw: factor out the retry logic
  mingw: change default of `core.symlinks` to false
  mingw: add symlink-specific error codes
  mingw: handle symlinks to directories in `mingw_unlink()`
  mingw: support renaming symlinks
  mingw: allow `mingw_chdir()` to change to symlink-resolved directories
  mingw: implement `readlink()`
  mingw: implement basic `symlink()` functionality (file symlinks only)
  mingw: add support for symlinks to directories
