mcctrl: refactor prepare_image into new generic ikc send&wait
...
Many ikc messages expecting a reply use wait_event_interruptible
incorrectly, freeing memory that could still be used on the other side.
This commit implements a generic ikc send and wait helper that helps
with memory management and ownership properly:
- if the message succeeds and a reply comes back normally, the memory
is freed by the caller as usual
- if the wait fails (signal before the reply comes or timeout) then the
memory is set as owner by ikc and will be free when the reply comes back
later
- if the reply never comes, the memory is freed at shutdown when
destroying ikc channels

ihk_os_getrusage(): Compile LWK-specific results in mcctrl
...
1. User asks mcctrl for the result via ihk_os_getrusage() with passing void *
2. mcctrl compiles the results and passes them to the user
3. User interprets it by using the type defined in the LWK-specific header
