by default, patterns/names in .gitignore are applied
recursively to all subdirectories. So any name mentioned
in .gitignore is ignored in all subdirectores. This is good
for, say. object files (*.o), but not good for particular
names which should be ignored only in one directory. For
example, qemu-img.1 file is generated in the top directory,
and it should be ignored only there, not in some subdir.
At first, this might not matter much, but we have lots of
examples already where it actually does not help at all.
For example, top-level .gitignore ignores a file/dir named
"patches" (which is very questionable by itself), but it
is applied recursively, so git also ignores, for example,
debian/patches/ which should not be ignored.
So anchor all the names where appropriate. .gitignore
should be cleaned up further, which will be addressed in
a subsequent patch.

Over time, lots of stuff moved from vl.c into separate
files. But include statements has never been cleaned,
and they continue to carry lots of anymore-unused stuff.
Remove includes which are not relevant for vl.c anymore.
Apparently there are more includes like this, because
many are included from qemu-common.h and the like, or,
for example, I don't see were we use win32-specific
stuff in vl.c (so that maybe #include <windows.h> might
be removed too).

Refactor do_socketcall() to do argument conversion/checking first,
according to a lookup table (which call has how many args) and
by calling the right function second with ready-to-go arguments.
This ensures that all arguments are handled as abi_long, according
to socketcall prototype, and simplifies argument handling alot too.

Commit 360e607 (address_space_translate: do not cross page boundaries,
2014-01-30) broke MMIO accesses in cases where the section is shorter
than the full register width. This can happen for example with the
Bochs DISPI registers, which are 16 bits wide but have only a 1-byte
long MemoryRegion (if you write to the "second byte" of the register
your access is discarded; it doesn't write only to half of the register).
Restrict the action of commit 360e607 to direct RAM accesses. This
is enough for Xen, since MMIO will not go through the mapcache.

IRQNoFlags on HPET._CRS crashes WinXP because it causes the HPET
to conflict with the system timer and/or the RTC. It only occurs
on Apple hardware, and even there it is exposed fully only when
OS X is detected (via _OSI). Recent OS X versions work on QEMU
without this statement, so at this time there is no need to find
a better way to conditionally include the statement. This patch
removes the commented out (and wrong, should have been {0, 8})

Currently it's possible to make PCIDevice not hotpluggable
by using no_hotplug field of PCIDeviceClass. However it
limits this only to PCI devices and prevents from
generalizing hotplug code.
So add similar field to DeviceClass so it could be reused
with other Devices and would allow to replace PCI specific
hotplug callbacks with generic implementation. Following
patches will replace PCIDeviceClass.no_hotplug with this
new property.
In addition expose field as "hotpluggable" readonly property,
