48e7cff259 LOOP: fix the todo calculations. 
The todo system was sucky as it was calculated in different
places in the mainloop and at each level. This was exposed by
calls to qb_loop_level_item_del() which decremented the level->todo
but not the mainloop one. So now we re-calculate it each time.

Fabio M. Di Nitto
d823a480dc Fix a compile warning on sparc (epoll_create1) 
The problem is that sys/epoll.h was broken on sparc and alpha for a
bunch of glibc releases.

glibc has the symbol correctly exported, that's why ./configure finds
it, but the header is not always correct. Recent versions of glibc have
the correct header, so we simply workaround the broken ones.

This fix is only necessary to build with --enable-fatal-warnings,
otherwise you simply see a build warning, but there are no runtime
issues at any stage.

2da98acd42 MAP: add a notifier purely to allow the user to free memory. 
At the moment if you have multiple notifiers it becomes impossible
to figure out when it is safe to free the values.

This new callback can only be added once and is called
once, making it better suited to freeing memory. It is
also called after the deleted and replaced notifiers.

Angus Salkeld
683296f180 Fix ringbuffer creation on sparc 
On the first call to qb_rb_open() we try using a number of
page sizes. This because the system might have CONFIG_HUGETLB_PAGE_SIZE
defined in their kernel. So even though sysconf() returns 2K or 4K
some arch's mmap() require alignment on these boundaries.

these logs will not make there way to /var/log/messags

So to help on the fly debugging do the following:
qb_log_ctl(QB_LOG_SYSLOG, QB_LOG_CONF_PRIORITY_BUMP,

Now all messages that have the QB_LOG_SYSLOG target set

4b58dda9fa get_more_jobs: use qb_list_splice instead of iterating list and readding 
oprofile picked up get_more_jobs as a heavy abuser of cpu cycles when running
with cpgbench.  Typical cpgbench runs this function 37 million times.  This
small optimization improves performance of corosync as well as reduces
cpu utilization used by this function.

Might look at tracking length of wait_head and job_head to avoid use of
qb_list_length as well (which also iterates).

the point is to use this for IPC to provide async

flow control.

This still needs a bit of clean up, but committing now
for feedback and as it is quite functional.
