Windows has junction points which function as symbolic links for directories. This patch introduces a new function TestLib::dir_symlink() which creates a junction point on Windows and a standard Unix type symbolic link elsewhere. The function TestLib::perl2host is also modified, first to use cygpath where it's available (e.g. msys2) and second to allow it to succeed if the gandparent directory exists but the parent does not. Given these changes the only symlink tests that need to be skipped on Windows are those related to permissions or to use of readlink. The relevant tests for pg_basebackup and pg_rewind are therefore adjusted accordingly. Andrew Dunstan, reviewed by Peter Eisentraut and Michael Paquier.
