Implement qXfer:exec-file:read in gdbserver
This commit implements the "qXfer:exec-file:read" packet in gdbserver.
gdb/gdbserver/ChangeLog:
* target.h (struct target_ops) <pid_to_exec_file>: New field.
* linux-low.c (linux_target_ops): Initialize pid_to_exec_file.
* server.c (handle_qxfer_exec_file): New function.
(qxfer_packets): Add exec-file entry.
(handle_query): Report qXfer:exec-file:read as supported packet.
