The count value can be used to batch timeouts. I.e., if a periodic
timeout triggered multiple times before the timer had a chance to
process them, the count corresponds to the number of passed periods.
and add xml configuration option to switch it on if required. Avoids trouble
on Windows 7 guest where IRQ injected by VMMDev PCI device is not delivered.
If ioapic is required and Windows guest addition "hangs", look in file
DevPCI.cpp, function pciSetIrqInternal, variable fIsApicEnabled. If
config[0xde] == 0xbe
config[0xad] == 0xef
it works. "Deadbeaf" seems to/should be set in ACPI file vbox.dsl. Happens for
unknown reason not on Genode/Nova.

On ARM it's relevant to not only distinguish between ordinary cached memory
and write-combined one, but also having non-cached memory too. To insert the
appropriated page table entries e.g.: in the base-hw kernel, we need to preserve
the information about the kind of memory from allocation until the pager
resolves a page fault. Therefore, this commit introduces a new Cache_attribute
type, and replaces the write_combined boolean with the new type where necessary.
In file
src/VBox/Additions/WINNT/SharedFolders/driver/file.c
the function
static int vbsfTransferCommon(VBSFTRANSFERCTX *pCtx)
in the
VbglR0CanUsePhysPageList()
branch does not correctly evaluate the read or written bytes from
the VMM. It ever assumes that whole pages are read/written.
Workaround the bug in the Windows guest additions of Vbox until fixed
upstream by filling up the read/write buffer completely within the VMM code
of Vbox.

This patch changes the top-level directory layout as a preparatory
step for improving the tools for managing 3rd-party source codes.
The rationale is described in the issue referenced below.
