Photon v0.12.1 with 50% faster eventloop

[Dmitry Olshansky]

So big news is that on Linux (and soon on other platforms) 
eventloop was rewritten to run faster especially in chatty apps 
that do lots of smallish send/recv ping pong. The end result is 
50% faster end-to-end memcached benchmark for my up and coming 
hedgehog[1] server. It's now actually 15-20% faster than stock 
memcached on memtier benchmark and about 50% faster on memcslap 
tests I carried out, this is far from extensive benchmarking and 
hedgehog is not even that optimized yet(!)

Of other notable additions is support for AArach64 on Linux. I 
basically spun up virtual machine on my Mac and to my dismay 
AArch64 was not supported yet so I fixed it making the code more 
portable going forward.

All in all I find that fibers can deliver as long as we are not 
going into millions of connections.
