This commit doesn't implement support for trapping on

arm: virt: Fix segmentation fault when specifying an unsupported CPU
Using -cpu cortex-a9 (or any other unsupported CPU) with the virt
board will cause QEMU to segmentation fault. This bug was introduced
in commit
9ac4ef77, which incorrectly added a NULL terminator when
converting the VirtBoardInfo array into a simple array of strings
defining the valid CPUs. The cpuname_valid() loop already has
a termination condition based on ARRAY_SIZE, so the NULL is
spurious and causes the strcmp() to segfault if we reach it.

net: optimize checksum computation
Very simple loop optimization with a significant performance impact.
Microbenchmark results, modern x86-64:
buffer size | speed up
------------+---------
1500 | 1.7x

8 | 1.15x
Microbenchmark results, POWER7:

There is a lot of room for further improvement at the expense of
code complexity - aligned multibyte reads, LE/BE considerations,
architecture-specific optimizations, etc. This patch still keeps
things simple and readable.

It has been modified to build and run along with the current code base.
The formatting has been fixed to go through scripts/checkpatch.pl,
and the DPRINTF macros have been updated to get the instanciations checked by
the compiler.
The FPU registers saving/restoring has been updated to match the current
QEMU registers layout.
The implementation has been simplified by doing the following modifications:
- removing the code for supporting the hardware without Unrestricted Guest (UG)
mode (including all the code to fallback on TCG emulation).
- not including the Darwin support (which is not yet debugged/tested).
- simplifying the initialization by removing the leftovers from the Android
specific code, then trimming down the remaining logic.
- removing the unused MemoryListener callbacks.

error: error_setg_errno(): errno gets preserved
C11 allows errno to be clobbered by pretty much any library function
call, so in general callers need to take care to save errno before
calling other functions.
However, for error reporting functions this is rather awkward and can
make the code on the caller side more complicated than
necessary. error_setg_errno() already takes care of preserving errno
and some functions rely on that, so just promise that we continue to
do so in the future.
