packages/core/ed.cc

missing 'check_valid_path(...)' for write operation with new api.

packages/core/file.cc

add support for 'lstat' if available
- efun::get_dir
- efun::file_size
- efun::stat / new efun::lstat ?
remove master::valid_link ?

efun::link internally uses efun::rename with it's inherit security checks against master::valid_write making either double checks or reducing master::valid_link to a simple switch: mudlib generally allows / forbids linking
alternative: remove dependency on efun::rename from efun::link and correctly support links within all relevant functions

path handling

simplify handling of paths:

There are dozends of places where paths are brought into some canonical form. Make sure each supplied path, either by mudlib, runtime configuration or generated by the driver itself, IS canonical and work from there...

vm/internal/simulate.cc
