[Replicant] libsamsung-ipc patches.

[Denis 'GNUtoo' Carikli]

Hi,

Here's a new round of patches for libsamsung-ipc master.

The idea is to merge them before the next Replicant 6.0 0004 release so
they would benefit from the testing.

They are mainly useful for Replicant 9 though as the compilation now
uses Werror. 

The patches were made as it's better and less time consuming to fix
the code than try to disable Werror.

Denis.
