Missing function implementations: fstatat, openat, readlinkat, fdopendir, getpwuid_r, getgrgid_r

Is there a way to get the actual implementations of these function into the ESP library? I'm stumped.

A fair amount of these things don't make sense in esp-idf context: we don't have PID/UIDs and as far as I am aware no filesystem we support handles symlinks. For the rest: as far as I can see, they're convenience functions and you should be able to write wrappers for them.

Add getpwuid() to that list. pwd.h says it has an implementation, but during compile, it cannot like to the function implementation. :(

@ESP_Sprite thanks for the reply. That's exactly what I am doing at the moment. I am trying to write the wrappers for some of the missing functions.
