Remove "set/show remotebaud" (deprecated) commands.

This patch removes support for the "set/show remotebaud" command,

ahead of cutting the GDB 7.8 branch.

        * serial.c (_initialize_serial): Remove support for
        the "set remotebaud" and "show remotebaud" commands.
        * NEWS: Add entry documenting the removal of that command.

        * config/monitor.exp (gdb_target_monitor): Replace use of
        "set remotebaud" by "set serial baud".

Fix demangler testsuite crashes with CP_DEMANGLE_DEBUG defined

Running the demangler's testsuite with CP_DEMANGLE_DEBUG defined
crashes, with:

 Program received signal SIGSEGV, Segmentation fault.
 0x000000000040a8c3 in d_dump (dc=0x1, indent=12) at ../../src/libiberty/cp-demangle.c:567
 567       switch (dc->type)

 (gdb) bt 3
 #0  0x000000000040a8c3 in d_dump (dc=0x1, indent=12) at ../../src/libiberty/cp-demangle.c:567
 #1  0x000000000040ae47 in d_dump (dc=0x7fffffffd098, indent=10) at ../../src/libiberty/cp-demangle.c:787
 #2  0x000000000040ae47 in d_dump (dc=0x7fffffffd0c8, indent=8) at ../../src/libiberty/cp-demangle.c:787

Note dc=0x1, which is obviously a bogus pointer.  This is the end of
d_dump recursing for a component type that that doesn't actually have
subtrees:

 787       d_dump (d_left (dc), indent + 2);
 788       d_dump (d_right (dc), indent + 2);

This fixes the two cases the testsuite currently trips on.
