Subject: [Ada] Improved exception message for Host_Error
Authentication-results: sourceware.org; auth=none

GNAT.Sockets.Host_Error is the exception raised when a host name
or address lookup fails. This change improves the associated exception
message by including the offending name or address

The following test case must display:

raised GNAT.SOCKETS.HOST_ERROR : [1] Host not found: nonexistent-host

with GNAT.Sockets; use GNAT.Sockets;
procedure Get_Nonexistent_Host is
   Dummy : Host_Entry_Type := Get_Host_By_Name ("nonexistent-host");
begin
   null;
end Get_Nonexistent_Host;

Tested on x86_64-pc-linux-gnu, committed on trunk

	* g-socket.adb (Raise_Host_Error): Include additional Name parameter.
