MEDIUM: connection: introduce "struct conn_src" for servers and proxies
Both servers and proxies share a common set of parameters for outgoing connections, and since they're not stored in a similar structure, a lot of code is duplicated in the connection setup, which is one sensible area. Let's first define a common struct for these settings and make use of it. Next patches will de-duplicate code. This change also fixes a build breakage that happens when USE_LINUX_TPROXY is not set but USE_CTTPROXY is set, which seem to be very unlikely considering that the issue was introduced almost 2 years ago an never reported.
