827cabb480 show: Use pr_msg for showing contents on console 
Due to code sharing, especially in IPC area,
the unbinding is done via helper macros and
sysclt engine tuning (new CTL_SHOW action
added).

f86d167bf1 ipc: rename struct ipc_seg 
This name for the structure is obfuscating, because the structure
will be used also for queues and semaphores sets migration.

This patch renames this structure int ipc_desc_entry. It also renames
all related functions and prints to reflect structure name change.
