  configure: add --target-list-exclude

This is an inverse selection which excludes a selected set of targets
from the default target list. It will mostly be useful for CI
configurations but it might be useful for some users as well.

You cannot specify --target-list and --target-list-exclude at the same
time.

  .travis.yml: split some more system builds

We define a new class of targets (MAIN_SOFTMMU_TARGETS) to cover the
major architectures. We either just build those or use the new
target-list-exclude mechanism to remove them from the list. This will
hopefully stop some of the longer builds hitting the Travis timeout
limit.

This is essentially a softmmu tweak so don't bother building
linux-user builds as well.

  .travis.yml: reduce number of targets built while disabling things

This build keeps timing out on Travis and it's unlikely including the
additional guest front-ends will catch any failures in the fallback
code.

  target/mips: Fix minor bug in FPU

Wrong type of NaN was generated for IEEE 754-2008 by MADDF.<D|S> and
MSUBF.<D|S> instructions when the arguments were (Inf, Zero, NaN) or
(Zero, Inf, NaN).

The if-else statement establishes if the system conforms to IEEE
754-1985 or IEEE 754-2008, and defines different behaviors depending
on that. In case of IEEE 754-2008, in mentioned cases of inputs,
<MADDF|MSUBF>.<D|S> returns the input value 'c' [2] (page 53) and
raises floating point exception 'Invalid Operation' [1] (pages 349,
350).

These scenarios were tested and the results in QEMU emulation match
the results obtained on the machine that has a MIPS64R6 CPU.

  hardfloat: fix float32/64 fused multiply-add

Before falling back to softfloat FMA, we do not restore the original
values of inputs A and C. Fix it.

This bug was caught by running gcc's testsuite on RISC-V qemu.

Note that this change gives a small perf increase for fp-bench:

  docker: Fix travis.py parser and misc change

Fixed the travis.py script that has failed to parse the current
QEMU_SRC/.travis.yml file. It no longer makes combinations from
env/matrix, instead it uses explicit includes. Also the compiler
can be omitted from matrix/include, so that Travis chooses the
first entry of the global compiler list.

Replaced yaml.load() with yaml.safe_load() so that quieting the
following deprecation warning:

  docker: Fix travis script unable to find source dir

The script generated from QEMU_SRC/.travis.yml uses BUILD_DIR and
SRC_DIR path relative to the current dir, unless these variables
are exported in environment.

Since commit 05790dafef1 BUILD_DIR is exported in the runner script,
although SRC_DIR is not, so that make docker-travis fails becase
the reference to source dir is wrong. So let's unset both BUILD_DIR
and SRC_DIR before calling the script, given it is executed from
the source dir already (as in Travis).
