Openat without die

[Bastien ROUCARIES]

Hi,

This two patches will allow to remove a xmalloc and bail out early in case of 
ENOMEM

I plan to implement a API reusing openat_permissive()

If openat_permissive cwd_errno is NULL use the slow but safe fork variant
else use the fchdir variant

Program that care could therefore use the more permissive variant (like for 
instance the critical fts  without FTS_NOCHDIR)

I program also to implement *at_permissive function

What do you think about that?

How could I easilly test this fallback under my quite recent debian ? Does I 
need to compile under a qemu image of old os ? Where 
could I find such an os ?
