arrakis merge: remove megaraid dependency for arm archs

Signed-off-by: Simon Gerber <simon.gerber@inf.ethz.ch>

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.

vfsfd: provide a thin library for unix-like system calls

Remove basic file operations from posixcompat, and put them to a separate
library calleed vfsfd. vfsfd will be used to implement newlib's stdio.

--HG--
rename : include/posixcompat/fdtab.h => include/vfs/fdtab.h
rename : lib/posixcompat/fdtab.c => lib/vfs/fdtab.c

Added AHCI driver (ahcid), AHCI user-space library (libahci), AHCI Flounder backend, block device file system (in libvfs), and various tests and benchmarks for the above.
Source: Distributed Systems Lab: A Messaging Interface to Disks (Manuel Stocker, Mark Nevill, Simon Gerber).

Added a library procon for producer/consumer based shared buffer management.
Also, added the library in the Hakefiles of all applications which needs it.

* Added compile trace replayer
* Disabled fixes to bcache locking
* Fixed hashtable to use const void instead of just void
* Made fopen buffer even bigger to preserve close-to-open semantics
for larger files.
* Worked around SCC bootup race (channel teardown NYI)

Initial version of public stable barrelfish repository.
