Jeff Squyres c8bb7537e7 Remove include/opal/sys/cache.h -- its only purpose in life was to
#define CACHE_LINE_SIZE to 128.  This name has a conflict on NetBSD,
and it seems kinda odd to have a header file that ''only'' defines a
single value.  Also, we'll soon be raising hwloc to be a first-class
item, so having this file around seemed kinda weird.

Therefore, I replaced CACHE_LINE_SIZE with opal_cache_line_size, an
int (in opal/runtime/opal_init.c and opal/runtime/opal.h) on the
rationale that we can fill this in at runtime with hwloc info (trunk
and v1.5/beyond, only).  The only place we ''needed'' a compile-time
CACHE_LINE_SIZE was in the BTL SM (for struct padding), so I made a
new BTL_SM_ preprocessor macro with the old CACHE_LINE_SIZE value
(128).  That use isn't suitable for run-time hwloc information,
anyway.

This commit was SVN r23349.
