Refactor process manager to enable spawnd discovery.

The process manager now allocates a special LMP endpoint for monitor.0 and
gives said endpoint to monitor.0 as part of the export_cb. After monitor.0
spawns spawnd, it uses that endpoint to send the new spawnd's iref to the
process manager. The latter then binds with spawnd, to keep track of its state.

For app cores, a similar workflow applies, except inter-monitor communication
is now performed. Namely, the new app core's monitor sends the new app core's
spawnd to monitor.0, which forwards it to the process manager. The latter then
binds with the app core's spawnd just the same.

Diagrams for the discovery protocol can be found at https://goo.gl/eJE37u.

Removed if/octopus_defs.h from public header file.

Referenced in definitions.h and trigger.h.

trigger.h is problematic because it provides helper functions for
types definied in the interface. Clients that want to use trigger.h
now have to make sure to include the interface file.

Fixed libbarrelfish spawn_client() and fish_arm to use standard functionality.

Return number of instance spawned in spawn_on_all_cores.

This also allows to remove the get_num_cores call in the
monitor and is the more sane approach anyways with dynamic
cores.

Change spawn_program_on_all_cores implementation.

We can no longer rely on monitor giving us core count.

Cleaned up remaining debug printfs.

monitor debug stuff + other debug msgs.

The Arrakis backport to Barrelfish.

Here are the macro changes:
* Made lwIP an optional network stack
* Moved lwIP headers out of the general include directory
* Parallel hake
* CPU-virtualized ("arrakis") applications
* libarrakis is a new libOS that uses CPU features directly
* arrakismon is a new monitor for Arrakis apps
* QEMU Multiboot support instead of GRUB (enables KVM)
* e10k virtual function driver
* Software virtual->physical mapping (substitutes IOMMU)
* To be replaced soon with an Intel IOMMU driver
* Better GDB and stack tracing support
* New POSIX support
* pthreads, inet_*(), usleep(), syslimits.h, sigaction(), mman.h,
* resource.h, sendmsg(), recvmsg(), mkfifo(), syslog.h, sysexits.h,
* fcntl(), getegid(), getgid(), pipe(), rlimits
* epoll support
* Separate waitset for interrupts
* Thread TLS key and ID support
* Moved PCRE headers to include/, where they usually are
* Intel performance counters support
* Handle boot-time RAM overflow (for machines with >=64GB RAM)
* Arranet network stack
* Fix for build of lib/barrelfish/arch/x86_64/dispatch.c without -O2
* New comandline options to pci daemon:
* maxvfs=x, x is number of virtual functions to create for each
* device supporting it
* skb_bridge_program=x, x is SKB bridge programming script to use
* bridge_bios is a script that uses the BIOS pre-set values, like Linux
* Correctly build machine-optimized newlib parts
* Library versions of e1000 and e10k drivers
* Support for virtualization in e10k driver
* e10k datacenter control plane daemon
* Modified hellotest to be both a Barrelfish and an Arrakis application

I've decided not to include the lwIP 1.4.1 code, as the port is
not finished and who wants to use lwIP anyway with the Arrakis
network stack and mTCP being released soon. If you want this,
let me know (it's hugely superior to lwIP 1.3.1).

I've made the code backwards-compatible with Barrelfish. The
default should do what Barrelfish does. One can specify
commandline options to the PCI daemon and e10k driver to
configure I/O virtualization and the optional arrakismon allows
loading CPU-virtualized "arrakis" programs.

There are more pending changes, such as support for hardware
rate limiting and weighted round robin packet scheduling, but
I'd like these to go in first, before I push the rest.

Refactor alloc_inheritcn_* to alloc_inheritcn_with_caps.

Instead of having an alloc_inheritcn_* function for each possible
capref in the inherit cnode.

add a spawn_wait_coreid() function

Patch by Mateusz Olczak <mateusz@olczak.se>

Refactor: Make 'cpu_type_to_archstr' a static inline function and move it to
header file where the enum cputype is defined.

various adjustments to tests and benchmarks to get the to run with arm_gem5, adjusted cpu clock to 1GHz, since a lot of configurations inside gem5 assume 1Ghz clock

Adding functionality to inherit capabilities and pass capabilities as arguments.

The function 'spawn_domain_with_fdcap' was used to spawn a domain and
inherit the file descriptors of the current domain. A similar inheritance
mechanism is needed for session capabilities.

To this end, the function was renamed to 'spawn_domain_with_caps'. It no longer
expects an fdcap as one of the arguments but a CNode containing all the
capabilities, that should be inherited by the newly spawned domain. The layout
of this CNode is convention an defined in include/barrelfish/spawn_client.h.
Spawnd knows about these capabilities and copies them to the appropriate places.
For example, if the fdcap is present in the inherit CNode, spawnd copies it to
the corresponding slot in the task CNode.

Moreover, we need the ability to pass arbitrary capabilities to a domain at
startup for example to start a device driver. Spawnd does not have to know about
these capabilities. Which capabilities are passed in which order is an agreement
between spawner and spawnee. To this end, this patch adds another CNode argument
to the function 'spawn_domain_with_caps'. If a domain wants to pass certain
capabilites to another domain it therefore creates a CNode and places the
capabilities in this Cnode and the passes this CNode as an argument to
'spawn_domain_with_caps'. Spawnd makes this CNode available to the spawnee in
the ARGCN slot of the root CNode as either a CNode (if spawner and spawnee are
on the same core) or a ForeignCNode (if on different cores).

The first method of inheriting capabilities and the second method of passing
capabilities are intentionally kept as two arguments because of the following
reasons:
* To account for the difference in their handling. Spawnd knows about the
inherited capabilities and places each of them to appropriate places in the
spawnee's CSpace. As a result they are available early-on, i.e. before the
library initialization code for this domain runs.
* Putting both kinds of capabilities in a single flat CNode, would require
recompilation of the whole OS after adding a new capability, that should be
inherited.

Added spawn_wait_core() to wait for a domain on another core to terminate
Note that I'm not really sure if that is the way to go, or if it is just
a work around, but for now it does the job.

Remove the dependency from fish on memclient and ramclient by moving the
required functionality into lib/barrelfish.

This ensures that there is no duplicate flounder code generation for the two
clients in fish.

Fixed spawn_program_on_all_cores() to check first whether a spawnd is
running before trying to spawn a program on that core.
