Track chronological fd metadata
This commit introduces a chrono_fds object as an attribute of Process
objects. In it, we track when the file (identified by its name)
associated to a given file descriptor has changed. The object
chrono_fds is indexed by file descriptor (number), and each value is
an OrderedDict which stores all the filenames and filetypes associated
with this fd, indexed by timestamp in nanoseconds.
Limitations: if a program opens a file, closes it, and reopens it with
the same file descriptor, without reusing the FD for any other file in
between, the change will not be tracked in chrono_fds.

Cleanup license (MIT)
Most of the code was already "kind of" MIT, somehow the last sentence of
the license was not present in the source files. Also, after the recent
refactoring, most of the new sources didn't have a proper license

This commit adds the proper MIT licensing header and copyright to every
