Unify the listen and connect code inside lldb-server to use ConnectionFileDescriptor uniformly rather than a mix of it and Acceptor. This involves: - adding a function to map legacy values of host:port parameter (including legacy server URLs) into CFD-style URLs - adding a callback to return "local socket id" (i.e. UNIX socket path or TCP port number) between listen() and accept() calls in CFD - adding a "unix-abstract-accept" scheme to CFD As an additional advantage, this permits lldb-server to accept any URL known to CFD including the new serial:// scheme. Effectively, lldb-server can now listen on the serial port. Tests for connecting over a pty are added to test that. Differential Revision: https://reviews.llvm.org/D111964
