[PATCH v2 for 5.0-rc3 00/17] more randome fixes (user, pie, docker and gdbstub)

[Alex Bennée]

Hi,

This is version 2 of my random fixes for rc3 series. In no particular
order we have:

  - A trivial fix to /proc/self/stat output
  - An attempt to fix broken PIE builds for Windows (please test!)
  - Some fixes to get "make docker-all-tests" running again
  - A tweak to .gitignore 
  - A couple of bugs found in the gdbstub GByteArray conversion
  - A new test case for linux-user gdbstub support
  - Which found a few more gdbstub bugs :-/

The m68k FPU patch is definitely a hack but it seemed easier than
disabling completely. The chatter on #gdb seems to be there is some
combination of qemu and gdb tress that does work but I suspect this
needs some maintainer action.

I've dropped the MacOSX travis patch as Travis has hopefully sorted
itself out.

I've also included the guest base re-factoring patches as it makes it
easier for me to soak test the tree with the sanitiser although those
actual fixes won't go into 5.0 at this late stage.

The following patches need review:

 - tests/tcg: add a multiarch linux-user gdb test
 - tests/tcg: drop inferior.was_attached() test
 - target/m68k: hack around the FPU register support (HACK!)
 - linux-user: completely re-write init_guest_space
