mini-os: repair build system
The build system of Mini-OS is using different settings for arch/*/*

Repairing this mess enables us to move the CONFIG_* handling to

mini-os: modify virtual memory layout for support of ballooning
In order to be able to support ballooning the virtual memory layout
of Mini-OS has to be modified: instead of a (nearly) consecutive
area used for physical memory mapping, on demand mappings, and heap
we need enough spare place for adding new memory.
So instead of dynamically place the different regions based on found
memory size locate them statically at fixed virtual addresses:
This will enable Mini-OS to support up to 512GB of domain memory with
a 64 bit kernel and nearly 1GB with a 32 bit kernel.
For a 32 bit Mini-OS we have to avoid a conflict between heap and
m2p table which the hypervisor maps at f5600000. So the demand mapping
size is reduced by 256MB in order to keep the heap at about 1GB.
The kernel virtual mappings are a new area needed for being able to
grow the p2m list without having to relocate it in physical memory.
Modify the placement of the demand mappings and heap and adjust the
memory layout description.

mini-os: fixed shutdown thread
Before, it read "" and started a shutdown immediately. Now, it waits for
a non-empty value and then actually shuts down.

mini-os: build fixes
Make .o rules depend on the includes. Before, only the final link step
depended on setting up the includes directory, making parallel builds
unreliable.
Make symlinks use explicit make rules instead of using a phony target.
Avoids unnecessary rebuilds.

mini-os: moved events code under arch
This is all code motion, except that we now initialise
the ev_actions array before calling the arch-specific code
to make it more robust against future changes.

mini-os: Fix stubdom build failures on gcc 4.8
This is a fix for bug 35:
http://bugs.xenproject.org/xen/bug/35
This bug report describes several format string mismatches which prevent
building the stubdom target in Xen 4.3 and Xen 4.4-rc2 on gcc 4.8. This is a
copy of Alex Sharp's original patch with the following modifications:
* Andrew Cooper's recommendation applied to extras/mini-os/xenbus/xenbus.c to
avoid stack corruption
* Samuel Thibault's recommendation to make "fun" an unsigned int rather than an
unsigned long in pcifront_physical_to_virtual and related functions
(extras/mini-os/include/pcifront.h and extras/mini-os/pcifront.c)
Tested on x86_64 gcc Ubuntu/Linaro 4.8.1-10ubuntu9.
