Patch to allow interrupting rdi target with SIGINT

[Grant Edwards]

Hi,

Attached is a patch against gdb-4.18 sources.  This patch can be
applied to 4.18 either before or after my previous rdi patches.  The
changes are listed below:


gdb/rdi-share/ardi.c:

 Added code from Thomas Zenker that enables the user to interrupt
 target execution by sending SIGINT (usually control-C) to gdb.
