a83ea01b99 bitbake: bitbake: asyncrpc: Catch early SIGTERM
If the SIGTERM signal is sent to an asyncrpc server before it has
installed the SIGTERM handler in the main loop, it may miss the signal
which will can cause the calling process to wait forever on the join().
To resolve this, the calling process should mask of SIGTERM before
forking the server process and the server should unmask the signal only
after the handler is installed. To simplify the usage of the server, an
new helper function called serve_as_process() is added to do this
automatically and correctly.

Thanks: Scott Murray <scott.murray@konsulko.com> for helping debug

57ec655acc bitbake: asyncrpc: Fix bad message error in client
If there is an issue with the format of the reply given by the server then we
should print this reply line in the error message. Printing the message which
the client sent doesn't illuminate anything here.

cba7d8f361 bitbake: asyncrpc: Add ping method
This method is needed to support startup of the prservice. As it is so
generic we can add it to the common asyncrpc module.

244b044fd6 bitbake: asyncrpc: Common implementation of RPC using json & asyncio
The hashserv module implements a flexible RPC mechanism based on sending
json formatted messages over unix or tcp sockets and uses Python's
asyncio features to build an efficient message loop on both the client
and server side. Much of this implementation is not specific to the
hash equivalency service and can be extracted into a new module for
easy re-use elsewhere in bitbake.
