Also add more test on sequential jobs

This reverts commit fe162ee2.

All options no longer require a short name.
-> rare options are only long now.

Some options have been renamed to sound clearer.
--mmax, --mmax-workload, --enable-sg-process-tracing,
--allow-time-sharing, --workflow-jobs-limit, ...

Some default values have been changed for consistency.
--mmax and --workflow-jobs-limit both have 0 as
default unlimited value.

Running batsim --help should now be more readable, and
display what can be done via the CLI.

In order to have deterministic workload names, I chose to use a hash function
rather than an uuid. The workload names are now the first 6 characters of the
hexadecimal representation of the SHA-1 of the absolute file name of the
workload file.

The regex part of the C++11 standard was not implemented before june 2015.
To avoid forcing users to have a very recent compiler, switching to boost instead.

Options have been added to:
  - enable warnings
  - treat warnings as errors
  - enable compile-time optimizations
  - disable run-time assertions

gcc/clang versions are checked to ensure they support c++11.
The C++11 flag is set manually to limit CMake version need.
The CMake version needed is now 2.8.11 (target_compile_definitions).

This modification impacts all parts of Batsim in which machines were involved.
The protocol has also been updated to allow the scheduler to send machine ranges
in its allocations. The previous syntax is still supported. Now, each comma-separated
value can either be 1 machineID or a range of machineIDs (syntax: machineIDa-machineIDb
to represent the closed interval [machineIDa, machineIDb]).

Please note that Batsim has been only been tested with old schedulers (that do not
support the new protocol syntax).

Separation of the network and the server in different files (which simplified the use of XBT_LOG). Minor fixes: missing enumerated cases in string conversion, use of a switch to generate a warning on future enumerated value misses. Minor cosmetic modifications.
