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.

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.

Upgraded Mesos to protobuf 2.5.0.

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.

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.

Upgraded to ZooKeeper 3.4.5.

In order to build Mesos with clang we need to upgrade
ZooKeeper. Unfortunately, Mesos leveraged some internal APIs of
ZooKeeper that changed so this commit required some refactorings.

Added a patch for glog required when compiling with clang.

Fixed warning given by clang.

Fixed protobuf::read bug exposed when running Mesos compiled by clang.

Refactorings necessary for getting clang to compile C++11 libprocess.

A test was also added that provides all possible examples of using
std::bind and lambda's with process::defer, Future::on* (Ready,
Failed, etc) and Future::then.

Added --with-cxx11 to libprocess configuration.

When building with clang we assume --with-cxx11. For example:

  CC=/path/to/clang CXX=/path/to/clang++ ../configure

But when building with gcc 4.8 you need to specify C++11:

  CC=/path/to/gcc CXX=/path/to/g++ ../configure --with-cxx11

At this point in time compiling using C++11 with gcc 4.8 on OS X does
not work with Python so it is explicitely disabled.
