This keeps breaking on Travis so lets just fall back to the Cirrus CI
builds which seem to be better maintained. Fix up the comments while
we are doing this as we never had a windows build.

As gdb will generally be talking to "foreign" guests lets use that if

  gdbstub: Introduce gdb_get_float64() to get 64-bit float registers

When converted to use GByteArray in commits 462474d760c and
a010bdbe719, the call to stfq_p() was removed. This call
serialize a float.
Since we now use a GByteArray, we can not use stfq_p() directly.
Introduce the gdb_get_float64() helper to load a float64 register.

Fixes: 462474d760c ("target/m68k: use gdb_get_reg helpers")
Fixes: a010bdbe719 ("extend GByteArray to read register helpers")

  tests/tcg: better trap gdb failures

It seems older and non-multiarach aware GDBs might not fail gracefully
when faced with something they don't know. For example when faced with
a target XML for s390x the Ubuntu 18.04 gdb will generate an internal
fault and prompt for a core dump.

Work around this by invoking GDB in a more batch orientated way and
then trying to filter out between test failures and gdb failures.

This test seems flaky and reports attachment even when we failed to
negotiate the architecture. However the fetching of the guest
architecture will fail tripping up the gdb AttributeError which will
trigger our early no error status exit from the test

  gdbstub: eliminate gdbserver_fd global

We don't really need to track this fd beyond the initial creation of
the socket. We already know if the system has been initialised by
virtue of the gdbserver_state so lets remove it. This makes the later
re-factoring easier.

  gdbstub/linux-user: support debugging over a unix socket

While debugging over TCP is fairly straightforward now we have test
cases that want to orchestrate via make and currently a parallel build
fails as two processes can't use the same listening port. While system
emulation offers a wide cornucopia of connection methods thanks to the
chardev abstraction we are a little more limited for linux user.
Thankfully the programming API for a TCP socket and a local UNIX
socket is pretty much the same once it's set up.

When the gdbstub code was converted to the new API we missed a few
snafus in the various guests. Add a simple gdb test script which can
be used on all our linux-user guests to check for obvious failures.

  target/m68k: fix gdb for m68xxx

Currently "cf-core.xml" is sent to GDB when using any m68k flavor.  Thing is
it uses the "org.gnu.gdb.coldfire.core" feature name and gdb 8.3 then expects
a coldfire FPU instead of the default m68881 FPU.

This is not OK because the m68881 floats registers are 96 bits wide so it
crashes GDB with the following error message:

(gdb) target remote localhost:7960

warning: Register "fp0" has an unsupported size (96 bits)
