Added freeMemory() to stout.

freeMemory() returns amount of free system memory. Can in
combination with memory() be used to get total used memory.
This allows future finer grained break-downs of used memory
in user memory, kernel buffers/caches and so on.

Adds Sigmoid Analytics to Powered By page.
Added a configure time check for building a native python egg.

This autoconf check does a rather complex test for covering MESOS-799.

It builds and test-runs a minimal egg that links against a static
library that imports a standard C++ library object. A static library
(built using the standard mesos build settings) is needed in this
puzzle because the egg producing distutils possibly use slightly
different build settings (derived from python-config).

If this check succeeds, we can be rather sure that the mesos-egg
itself will be functional from a build-env point of view.

Added missing trailing slash and 'f' in Makefile.am.

Commit 2026b0dd2a337e3873283ba501d7a5eb75aa9cfa updated the Makefile
but missed a trailing slash to append the file list.

The .woff font file was also missing an extra 'f', which prevented
make from finding it

Merged freeMemory() into memory().

Instead of having separate functions to get total and free system
memory, this patch merge the two in memory().
memory() now returns a struct containing both stats.

Review: https://reviews.apache.org/r/16769
Updated slave to use new memory struct.

From #16769, memory() now returns both total _and_ free system memory.
This patch adjusts for the new return type.

Replaced 'std::tr1' with 'lambda' and 'memory' in stout.

The 'lambda' and 'memory' namespace gives us a level-of-indirection
that makes it easier to do either C++03 or C++11 compilation.

Review: https://reviews.apache.org/r/16654
Replaced 'std::tr1' with 'lambda' and 'memory' in libprocess.

Some fixes and enhancements were also made to the C++11 version of the
library. At this point libprocess can be compiled for C++11 and all
tests pass with gcc 4.8.
