HPX V0.7.0

We have had roughly 1000 commits since the last release and we have closed approximately 120 tickets (bugs, feature requests, etc.).

General Changes

Completely removed code related to deprecated AGAS V1, started to work on AGAS V2.1.
Started to clean up and streamline the exposed APIs (see 'API changes' below for more details).
Revamped and unified performance counter framework, added a lot of new performance counter instances for monitoring of a diverse set of internal HPX parameters (queue lengths, access statistics, etc.).
Improved general error handling and logging support.
Fixed several race conditions, improved overall stability, decreased memory footprint, improved overall performance (major optimizations include native TLS support and ranged-based AGAS caching).
Added support for running HPX applications with PBS.
Many updates to the build system, added support for gcc 4.5.x and 4.6.x, added C++11 support.
Many updates to default command line options.
Added many tests, set up buildbot for continuous integration testing.
Better shutdown handling of distributed applications.

Example Applications

quickstart/factorial and quickstart/fibonacci, future-recursive parallel algorithms.
quickstart/hello_world, distributed hello world example.
quickstart/rma, simple remote memory access example
quickstart/quicksort, parallel quicksort implementation.
gtc, gyrokinetic torodial code.
bfs, breadth-first-search, example code for a graph application.
sheneos, partitioning of large data sets.
accumulator, simple component example.
balancing/os_thread_num, balancing/px_thread_phase, examples demonstrating load balancing and work stealing.

API Changes

Added hpx::find_all_localities.
Added hpx::terminate for non-graceful termination of applications.
Added hpx::lcos::async functions for simpler asynchronous programming.
Added new AGAS interface for handling of symbolic namespace (hpx::agas::*).
Renamed hpx::components::wait to hpx::lcos::wait.
Renamed hpx::lcos::future_value to hpx::lcos::promise.
Renamed hpx::lcos::recursive_mutex to hpx::lcos::local_recursive_mutex, hpx::lcos::mutex to hpx::lcos::local_mutex
Removed support for Boost versions older than V1.38, recommended Boost version is now V1.47 and newer.
Removed hpx::process (this will be replaced by a real process implementation in the future).
Removed non-functional LCO code (hpx::lcos::dataflow, hpx::lcos::thunk, hpx::lcos::dataflow_variable).
Removed deprecated hpx::naming::full_address.
