In commit 9ff18faf (fetch-pack: ignore SIGPIPE in sideband demuxer, 2016-02-24), we started using sigchain_push() to ignore SIGPIPE in the async demuxer thread. However, this is rather clumsy, as it ignores SIGPIPE for the entire process, including the main thread. At the time we didn't have any per-thread signal support, but we now we do. Let's use it.
