Use uv_fs_realpath() instead.
It seems that uv_fs_realpath() has some problems on non-Linux platforms:
- macOS and other BSDs: this function will fail with UV_ELOOP if more
than 32 symlinks are found while resolving the given path. This limit
is hardcoded and cannot be sidestepped.
- Windows: while this function works in the common case, there are a
number of corner cases where it doesn't:
- Paths in ramdisk volumes created by tools which sidestep the Volume
Manager (such as ImDisk) cannot be resolved.
- Inconsistent casing when using drive letters.
- Resolved path bypasses subst'd drives.
Ref: https://docs.libuv.org/en/v1.x/fs.html#c.uv_fs_realpath
I don't know if the old implementation that uses uv_chdir() and uv_cwd()
also suffers from the same problems.
- For the ELOOP case, chdir() seems to have the same limitations.
- On Windows, Vim doesn't use anything like chdir() either. It uses
_wfullpath(), while libuv uses GetFinalPathNameByHandleW().
