[PATCH v2 0/2] fix eal: unregister alarm callback before free

[Rui Ferreira]

This was flagged by Address sanitizer as a use after free in Linux. A
pointer is freed in the main thread but used by a callback in another thread.
It can be reliably reproduced in Linux with ASAN but I could not trigger the
same issue in FreeBSD.

I've included nearly identical patches for Linux and FreeBSD. I did not
include any changes for Windows since the same issue does not seem to apply
there (thread is actually cancelled, no shared ptr).
