Stripped down to just contain the parlib sources

Also now set up to build using autoconf and automake tools
and install via standard GNU mechanisms.

Also fixed up licenses across all files.

+Installation instructions
+
+To install this library, simply follow the standard GNU installation procedure.
+
+If building out of the git source repo, you will need to rerun autoconf and
+automake.  You can do these two steps together, by just running autoreconf.
+You therefore need to have the autotools installed on your system.
+The installation procedure would be:
+
+autoreconf --install
+mkdir build
+cd build
+../configure --prefix=<install_dir>
+make
+make install
+
+To clean up all generated files and get back to only files tracked by the git
+repo, you can simply run:
+
+git clean -x -d -f
+
+If building out of the tarball distribution, you can skip the autoreconf step
+entirely, as the files it generates are already provided to you (you can still
+do it if you like though).
+
+mkdir build
+cd build
+../configure --prefix=<install_dir>
+make
+make install
+
+Don't forget to use 'sudo' if you are installing into a directory which
+requires root priveleges.

+* This is a Linux ONLY port of the Parlib library
+* Unless otherwise noted in individual files, all software contained in this

+
+The Parlib library was originally written for the Akaros operating system.  For
+this reason, this port was originally designed as an emulation layer on top of
+Linux that would allow developers to write applications and test them on a
+linux system before deplying them on Akaros.
+
+Since its original inception, however, we've discovered that Parlib is useful
+in its own right as a standalone library on linux for use by other projects.
+Most notably, as the backend for the Lithe implementation.
+
+At present, Parlib provides 3 primary services to developers:
+1) A virtual core (vcore) abstraction
+2) A user-level thread (uthread) abstraction
+3) User-space Mcs and Spin Locks
