This function can be called when one needs to check disk space. If the
disk space is below a specified percentage threshhold, the function
notifies the system administrators.
A boolean is returned to indicate the disk space situation.

Utility function to prevent from having a None value.
This can be useful when giving values from the DB to
functions that only expect defined values (eg. when sorting)

More of the old permission system is being replaced by the new method

Safe encoding for first names and last names systematically.
Not only when we cannot view the full names.

Prefer using unicode(s).encode('utf-8') than unicode(s, 'utf-8'). Why? Don't know.

It can be (and will be) useful elsewhere.

JSON files produced by Vidjil can be huge (dozens or hundreds of megabytes) and we
do not want to load them all. We just load a short prefix of the file.
Since the json module expects a well-formed JSON string we use the
cleanup_json_sample to close the JSON input

One which directly takes the names in parameters (avoiding DB calls), another
taking te patient ID. The former is the recommended when the function is called many times.

Additionnally if the last parameter of anon_names is provided no DB call is performed.

This is used in several places in models/task.py and in modules/vidjil_utils.py.
