mboxd: Make window size and number optional command line parameters
The window size and number command line parameters are used to control
the number of windows and the size of each of the windows in the window
cache which the reserved memory region is divided between.
Most people won't care about tuning these or just won't know what they
refer to. Additionally in the event we change how the window cache
works or allow a non-constant window size then the meaning of these
becomes unclear.
Daemon implementations may also choose to just not implement a cache so
making these required parameters may hurt portability.
Make the window size and number command line parameters optional rather
than required so that they can be largly ignored while people who really
care about tuning them can still do so.
The default for now is to have windows of size 1MB and to map the entire
reserved memory region. That is:
number of windows = size of memory region / size of windows
This means that the size of the reserved memory region can be reduced
and the daemon will adapt to this.
