since v1:
-flag _ODP_SHM_PROC_NOCREAT and _ODP_SHM_O_EXCL get new values
(but remain useless: Should be removed when IPC is updated)  (Maxim)

-In get_ishm_flags(), odp_shm_capability() local variable flgs renamed
(for be better distinction from other "flags" variable. (Maxim)

-Added doc updates with shm api extensions. (Christophe)

This Patch series aims at using _ishm as north API memory allocator.
odp_shared_memory.c just becomes a wrapper around _ishm.
_ishm supports "process mode", i.e. memory allocated  with _ishm
is sharable by all ODP threads of a given ODP instance, regardless of
thread type (e.g. process) or thread creation time (for time).

NOTE: This patch series will break IPC: This is due to the fact that
IPC relied on a "special case" in the former memory allocator that broke
ODP instance scoping. I don't think this should kept.
I have included in this patch series a function to share memory between
designated ODP instances. If we want to have IPC, it should use that.
