Minor rewording of message containing name of program that generated a

core file (core.c), permanently remove the register_addr() stub (elfread.c),
move a misplaced #endif (procfs.c), and add fetch_core_registers func for
core file support (procfs.c).

+       fetch_core_registers -- fetch current registers from core file data
+
+SYNOPSIS
+
+       void fetch_core_registers (char *core_reg_sect, unsigned core_reg_size,
+                                  int which)
+
+DESCRIPTION
+
+       Read the values of either the general register set (WHICH equals 0)
+       or the floating point register set (WHICH equals 2) from the core
+       file data (pointed to by CORE_REG_SECT), and update gdb's idea of
+       their current values.  The CORE_REG_SIZE parameter is ignored.
+
+NOTES
+
+       Use the indicated sizes to validate the gregset and fpregset
+       structures.
