Fix PR breakpoints/16101: gdb.base/dprintf.exp agent-printf failures with non-Z0-supporting gdbservers

After a previous patch that was committed by Pedro (0000e5cc), trying
to set a dprintf with with a GDBserver that doesn't support agent
commands at all now throws an error.  But the dprintf tests still fail
with some GDBserver targets because they doesn't try to handle the
case of the server reporting support for breakpoint commands, but not
be able to use those in combination with Z0 (because Z0 isn't actually
supported, for example):

 FAIL: gdb.base/dprintf.exp: 1st dprintf, agent
 FAIL: gdb.base/dprintf.exp: 2nd dprintf, agent
 FAIL: gdb.base/dprintf.exp: dprintf info 2 (pattern 4)

Similarly for the MI test.

This patch makes the tests handle this scenario.

Tested with native, and native gdbserver on x86_64 Fedora 17.

Also tested with the native-gdbserver.exp board hacked with:

 set GDBFLAGS "${GDBFLAGS} -ex \"set remote breakpoint-commands off\""

(actually, "set remote breakpoint-commands off" is presently broken,
so this was on top of a fix for that command.)

which results in:
 (gdb) PASS: gdb.base/dprintf.exp: 2nd dprintf, gdb

(One of the new comments mentions breakpoint always-inserted mode.
Actually testing with breakpoint always-inserted mode fails these
dprintf tests, due to the way they are written.  But that'll take a
more substancial rewrite of the tests, so I'm leaving that for another
day.)

bfd/elfnn-aarch64.c: Fix calculation of DT_RELASZ

The current code subtracts the size of the output section containing
relplt from RELASZ. In some cases this will be the same output
section as the dynamic relocs causing a value of zero to be output.
Calculating the size from input sections seems to make more sense.

"source", foreground execution commands, and target-async

Sourcing a GDB script that runs foreground execution commands in
succession fails if the target can async:

 Breakpoint 1, main () at ../../../src/gdb/testsuite/gdb.base/source-execution.c:36
 36        func1 ();
 (gdb) source ../../../src/gdb/testsuite/gdb.base/source-execution.gdb
 ../../../src/gdb/testsuite/gdb.base/source-execution.gdb:21: Error in sourced command file:
 Cannot execute this command while the selected thread is running.
 (gdb) FAIL: gdb.base/source-execution.exp: source source-execution.gdb

That is, after a foreground execution command, GDB moves on to the
following command immediately before waiting for the previous command
to complete.

https://sourceware.org/ml/gdb-patches/2011-09/msg00037.html (b4a14fd0)
addressed this for command lists, Python's gdb.execute, etc., but
missed "source".  Fixed now in the same way.

Skip tests on completion and readline when readline lib isn't used

The completion feature and other features on readline depend on the
readline library.  However, readline library is not always used, for
example, running testsuite like

  make check RUNTESTFLAGS="--host_board=local-remote-host"

the input stream is not a tty, and GDB doesn't use readline library
as a result.

This patch is to skip tests on completion and readline if
'show editing' is off, which means readline isn't used.  Note that
some tests in gdb.base/completion.exp test command complete, which
isn't related to readline, so these tests aren't affected by readline
library.  This patch also moves these tests up, run them
unconditionally, and run the rest if readline library is used.

Referencing a function's address on PowerPC64 ELFv2

ELFv2 needs to create plt entries in a non-PIC executable for an
address reference to a function defined in a shared object.  It's
possible that an object file has no features that distinguish it as
ELFv1 or ELFv2, eg. an object only containing data.  Such files need
to be handled like those that are known to be ELFv2.
However, this unnecessarily creates plt entries for the analogous
ELFv1 case, so arrange to set output abi version earlier, and use the
output abi version to further distinguish ambiguous input files.
