bf7a74d47e Helper for moving image fd 
When opening an fd at a position where the current image fd sits
the latter one should be moved.

Introduce a helper for this.

83fd63d3fe Add missing extern to function prototypes 
Regardless that we link all things in one executable
better declare them so from the very beggining.

2c237b6973 Don't use standard descriptors for logging 
The standard descriptors may be redirected.

crtool dumplicates stderr in rlimit.maxfileno-1 and this descriptor
is inherited by all children and will be closed before sigreturn.

Known issues:

 - The logging descriptor may be used by a target process and
   a resume will fail.
