rtl/string.hxx and rtl/ustring.hxx both unnecessarily #include <sal/log.hxx> (and don't make use of it themselves), but many other files happen to depend on it. Cleaned up some, but something like grep -FwL sal/log.hxx $(git grep -Elw \ 'SAL_INFO|SAL_INFO_IF|SAL_WARN|SAL_WARN_IF') -- \*.cxx) shows lots more files that potentially need fixing before the include can be removed from rtl/string.hxx and rtl/ustring.hxx.

UNO Remote Protocol (URP). A binary protocol. UNO provides a protocol called the UNO Remote Protocol (URP) that provides a bridge between UNO environments. This bridge allows processes and objects to send method calls and to receive return values. UNO objects in different environments are connected by way of this interprocess bridge. The underlying connection is made through a socket or pipe. Remote UNO objects are connected by means of TCP/IP using the high-level protocol of the URP.
