Some functions in the time manager, for example 'TMTimerSet()' and
'TMTimerStop()' let VirtualBox abort with a failed assertion if the timer
does not change to a 'stable' state after 1000 calls of a mixture of
'yield' and 'sleep'. On Genode, this happens sometimes when the 'EMT'
thread is executing 'TMTimerSet()' and gets interrupted by the 'TAP'
thread, which calls 'TMTimerStop()' and waits for the 'EMT' thread to
finish setting the timer. Since the 'EMT' thread has the lowest priority,
1000 retries can be too few. Without the assertion, these functions would
return an error code, which is often ignored by the caller, so it seems
safer to keep retrying until the function can return successfully.

Be less verbose regards warnings caused by vmx_invalid exits - which triggers
on T400 more often because it has no Unrestricted Guest support. This leads
to lot of log messages so that the test does not succeed in time. Additionally,
the virtualbox_auto_disk.run script is adjusted to check for some output to
exit earlier if something went wrong.

When the 'Mtd::FPU' flag is set during the registration of a
virtualization event handler, it must also be set whenever the event
handler returns.
Fixes#1283
* repos/ports/include/vmm
- add support to specify cpu location during vCPU construction
* seoul
- update to latest seoul branch supporting smp
- adjust to vmm interface changes
- vCPUs will be put in a round robin fashion on the available host CPUs,
beginning with the next CPU after the default (boot) CPU
- number of vCPUs can be specified in run script
* virtualbox
- adjust to vmm interface changes
- uses still one vCPU, placed on default (boot) CPU
Fixes#1212
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.
Fixes#1188
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.
