bfdc4138ba seoul: remove superfluous includes from console
The console included nitpicker_view headers, which were not used. The
headers vanished with the recent nitpicker API change, which broke the
build of seoul.

6820de51ba gdb_monitor: Support session upgrades
This patch enables the debugging on services that rely on dynamic
session upgrades. For example, nitpicker expects its clients to donate
RAM quota that matches the size of the virtual framebuffer, which might
change during the lifetime of a nitpicker session.

* 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

a46de84f89 Fix race condition in page fault notification
When a page fault cannot be resolved, the GDB monitor can get a hint about
which thread faulted by evaluating the thread state object returned by
'Cpu_session::state()'. Unfortunately, with the current implementation,
the signal which informs GDB monitor about the page fault is sent before
the thread state object of the faulted thread has been updated, so it
can happen that the faulted thread cannot be determined immediately
after receiving the signal.

With this commit, the thread state gets updated before the signal is sent.

At least on base-nova it can also happen that the thread state is not
accessible yet after receiving the page fault notification. For this
reason, GDB monitor needs to retry its query until the state is
accessible.

Fixes #1206.

ca9f0ba89c os: extend on_alarm() by unsigned count value
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.

786fe805da base: introduce caching attributes (fix #1184)
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.

ca971bbfd8 Move repositories to 'repos/' subdirectory
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.
