Sascha Hauer 6188685091 Make errno a positive value 
Normally errno contains a positive error value. A certain unnamed developer
mixed this up while implementing U-Boot-v2. Also, normally errno is never
set to zero by any library function.
This patch fixes this.

Sascha Hauer 8cab6a8733 parameter: return empty string for unset parameters 
Currently we return NULL for unset parameters. As we can't set them
back to NULL once set this is not very consistent. Return an empty
string instead.

Sascha Hauer c3789cd49b rework device parameters 
Change device parameters so that the memory management is in generic
code. This also removes the need of storing statically initialized
parameters as they are stored in a struct list_head for each device.

Sascha Hauer c0d02ffc3d Fix string_to_ip 
Use a pointer to an ip address instead of the return value in string_to_ip
and use the return value for error indication only. 0.0.0.0 can be a valid
ip address
