78b27bade1 libqtest: Add qtest_[v]startf()
We have several callers that were formatting the argument strings
themselves; consolidate this effort by adding new convenience
functions directly in libqtest, and update some call-sites that
can benefit from it.

Note that the new functions qtest_startf() and qtest_vstartf()
behave more like qtest_init() (the caller must assign global_qtest
after the fact, rather than getting it implicitly set).  This helps
us prepare for future patches that get rid of the global variable,
by explicitly highlighting which tests still depend on it now.

357d1e3bc7 spapr: Improved placement of PCI host bridges in guest memory map
Currently, the MMIO space for accessing PCI on pseries guests begins at
1 TiB in guest address space.  Each PCI host bridge (PHB) has a 64 GiB
chunk of address space in which it places its outbound PIO and 32-bit and
64-bit MMIO windows.

This scheme as several problems:
  - It limits guest RAM to 1 TiB (though we have a limited fix for this
    now)
  - It limits the total MMIO window to 64 GiB.  This is not always enough
    for some of the large nVidia GPGPU cards
  - Putting all the windows into a single 64 GiB area means that naturally
    aligning things within there will waste more address space.
In addition there was a miscalculation in some of the defaults, which meant
that the MMIO windows for each PHB actually slightly overran the 64 GiB
region for that PHB.  We got away without nasty consequences because
the overrun fit within an unused area at the beginning of the next PHB's
region, but it's not pretty.

This patch implements a new scheme which addresses those problems, and is
also closer to what bare metal hardware and pHyp guests generally use.

Because some guest versions (including most current distro kernels) can't
access PCI MMIO above 64 TiB, we put all the PCI windows between 32 TiB and
64 TiB.  This is broken into 1 TiB chunks.  The first 1 TiB contains the
PIO (64 kiB) and 32-bit MMIO (2 GiB) windows for all of the PHBs.  Each
subsequent TiB chunk contains a naturally aligned 64-bit MMIO window for
one PHB each.

This reduces the number of allowed PHBs (without full manual configuration
of all the windows) from 256 to 31, but this should still be plenty in
practice.

We also change some of the default window sizes for manually configured
PHBs to saner values.

Finally we adjust some tests and libqos so that it correctly uses the new
default locations.  Ideally it would parse the device tree given to the
guest, but that's a more complex problem for another time.

9be385980d coccinelle: Remove unnecessary variables for function return value
Use Coccinelle script to replace 'ret = E; return ret' with
'return E'. The script will do the substitution only when the
function return type and variable type are the same.

Manual fixups:

* audio/audio.c: coding style of "read (...)" and "write (...)"
* block/qcow2-cluster.c: wrap line to make it shorter
* block/qcow2-refcount.c: change indentation of wrapped line
* target-tricore/op_helper.c: fix coding style of
  "remainder|quotient"
* target-mips/dsp_helper.c: reverted changes because I don't
  want to argue about checkpatch.pl
* ui/qemu-pixman.c: fix line indentation
* block/rbd.c: restore blank line between declarations and
  statements

2ad645d285 qtest: Use -display none by default
This avoids each test needing to add it to suppress windows popping up.

[Commit 7ceeedd016 ("blockdev-test: add
test case for drive_add duplicate IDs") and commit
43cd209803 ("qdev-monitor-test: add
device_add leak test cases") added qtest tests without specifying
-display none.

As a result, "make check" now tries to use graphics (GTK or SDL).  Since
graphics are not used by the test and inappropriate for headless "make
check" runs, add the missing -display none.

This fixes "make check" in the QEMU buildbot.
