Summary: expose fsync() to the tcl level

Initial Comment:
With the advent of new file systems such as Ext4, the time between file system syncs will increase to improve performance. At the Tcl script level, it may be advantageous to have an option to fsync a file on close, or fsync after a write.

kbk: suggested fconfigure $chan -synconclose 0
ƎƎ:  suggested fconfigure $chan -synconwrite 1 as well.
kbk: responded with [chan sync $chan] as synconwrite would be a bit excessive; explicit-sync makes more sense.
