Merge branch 'master' into phaser
* master: (47 commits)
runtime: disable the Nagle algorithm entirely.
runtime: buffer RPC send packets.
runtime: don't print debug messages to the UART.
runtime: print microsecond timestamps in debug messages.
artiq_devtool: abort if build failed.
conda: bump llvmlite-artiq dep.
conda: bump llvmlite-artiq dep.
llvm_ir_generator: use !{→unconditionally.}invariant.load metadata.
artiq_devtool: more robust port forwarding.
setup: remove paramiko dependency (optional and developer-only)
artiq_devtool: implement.
artiq_compile: actually disable attribute writeback.
conda: use pythonparser 1.0.
conda: tighten pythonparser dependency (fixes #600).
doc: clarify kernel_invariant doc (fixes #609).
compiler: Emit all-kernel_invariant objects as LLVM constants
conda: update for LLVM 3.9.
add has_dds, use config flags

Asynchronous RPCs

-----------------
|

|

If an RPC returns no value, it can be invoked in a way that does not block until the RPC finishes

execution, but only until it is queued. (Submitting asynchronous RPCs too rapidly, as well as
|
||||
submitting asynchronous RPCs with arguments that are too large, can still block until completion.)
|

To define an asynchronous RPC, use the ``@rpc`` annotation with a flag: ::
