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.

8a673559e7 Fixed segment fault bug when use logging API at i386 platform 
This bug cause by qb_vsprintf_serialize function. It parse "%llx" format
as _long_ other than _long long_.

At x86_64 platform, both sizeof(long) and sizeof(long long) is 8, this
issue would not be triggered, so we could only catch it at i386.
