[fusil] [announce] Release of Fusil version 1.1

[Victor Stinner]

User visible changes:
 * replay.py: ask confirmation if the fuzzer will not be running under a
   different user or as root
 * Even with --force-unsafe, show safety warning if the fuzzer is
   running as the root user
 * Close files for child processes (close_fds=True)

Developer changes:
 * Create IntegerRangeGenerator in fusil.unicode_generator
 * Create EnvVarIntegerRange in fusil.process.env
 * Create fusil-wizzard fuzzer
 * Write timestamp in session.log
 * Add session() method to ProjectAgent
 * Add NAME attribute to a fuzzer, reused to choose the project directory name

Bugfixes:
 * Fix Debugger.processSignal(): use the process agent to send the message
   (session_rename) since the debugger agent may be disabled
 * Fix replay.py: quote gdb arguments escape quote and antislash characters
   (eg. "text=\"Hello\\n\".")
 * replay.py uses /dev/null for stdin as Fusil does
 * FileWatch: open file in binary mode to use bytes in Python3
