Rob Norris 1f8c39ddb2 ZTS: test response of various sync methods under different failmodes
These are all the same shape: set up the pool to suspend on first write,
then perform some write+sync operation. The pool should suspend, and the
sync operation should respond according to the failmode= property.

We test fsync(), msync() and two forms of write() (open with O_SYNC, and
async with sync=always), which all take slightly different paths to
zil_commit() and back.

A helper function is included to do the write+sync sequence with mmap()
and msync(), since I didn't find a convenient tool to do that.
