20d2725ed9 core: shared_ptr add noexcept 
Add missing noexcepts. Those on constructors are needed to be able to
store shared pointers in growable containers efficiently.

Network stack inversion: tcp, from Gleb.

TCP now does not transmit on a user write; instead it signals that
packets can be generated to the IP layer.  When the IP layer is polled,
it will poll TCP in turn and generate packets.  This improves batching.

32b42af49f net: register l3 poller for tcp connections 
This patch change tcp to register a poller so that l3 can poll tcp for
a packet instead of pushing packets from tcp to ipv4. This pushes
networking tx path inversion a little bit closer to an application.

3be04e7009 reactor: implement open_directory(), list_directory() 
open_directory() is similar to open_file_dma() with just the O_ flags adjusted.

list_directory() returns a subscription(), so that both the producer and

a5802e36a2 Merge branch 'gleb/net' of github.com:cloudius-systems/seastar-dev 
Network tx path inversion, from Gleb:

"Instead of pushing packets from upper layers towards HW those patches
change networking stack to do the opposite: HW polls upper layers for
packets to send. There are several advantages to this approach. First
one is that now, instead of getting packets one by one HW will get them
in bulks. Another is that packet queueing happens closer to an application
layer where sender can be stopped more accurately without dropping packets."
