tracing: make larger trace buffers possible

Init allocates the Frame cap for the shared trace buffer. As we only gave init
16MB for it's memory allocator, this could fail for larger machines (e.g.
babybel). This commit increases the maximum number of cores for tracing to 32,
and the per-core trace buffer to 20'000 events.

Initial AArch64/ARMv8 skeleton.

This includes enough code and definitions to generate all *.depend files for
AArch64/ARMv8 and to build a mostly empty cpu driver for the Applied Micro
X-Gene 1 (apm88xxxx) SoC.

Note: the definitions should be taken with a large grain of salt, some of them
are not updated for AArch64/ARMv8.

tracing: Fixed some bugs.

Add TRACE macro to make writing trace_events less verbose.

Added missing includes after merge.

Cleaned up code and removed all the debugging related code

Webserver working for full website with LMP.

This version of code still does not work for UMP,
and also it does not work for httperf test.

Also, there is lot of commented out code which was helpful for me
in debugging the issue of randome page-fault.

Webserver working for small websites

Partially working version of the modified network stack.
Status: Networking works
Small website test works (Barrelfish website without pdfs)
Full website test does not work (Barrelfish website with pdfs)
Tests done with e1000n running on separate core

Cleanup trace.h.

trace: make it compile for x86_32

trace: make it compile for arm

Due to a string.h include, had to rename some index variables to idx, because
they shadow index(3).

New tracing infrastructure

This is a Distributed Systems Lab project by
Alexander Grest <agrest@student.ethz.ch> and David Stolz <stolzda@ethz.ch>

Added tracing events for low latency networking

Removed the additional ring from packet send path. The driver code for e1000n
and e10k is modified but code for other drivers (eMAC, and rtl) is still to
be modified.

remove support for Beehive

see the mailing list discussion at the end of December 2011 for motivation

Added profiling code for latency in connection with e10k.

limit pre-allocated trace buffers to the first 64 cores

Since increasing MAX_CPUS, tracing code which tries to allocate a
buffer for every possible core was running out of memory early in
boot. This is a kludgy quick fix; better ones include:

* allocating the memory either in the kernel before starting init, or
later when the memory server is up
* allocating a trace buffer for a core dynamically when that core boots

Removed most of the debugging code which was breaking the compilation for arm

Converted the pic and xapic drivers to use the Mackerel shift driver syntax.

Changes to get RX benchmark working.
There are lot of small changes in this commit and also extra code for debugging
and performance evaluation which will be cleaned in future versions.

Apply the multihop patch by alexander grest based on his bachelor thesis
