API change: mysql_shutdown() now needs a 2nd parameter, the shutdown level.

Server will however still accept shutdown without specified level; so that old
mysqladmin can still shut server down.
I would like your comments on the names of shutdown level which I chose. You
are welcome to propose better names. Please however check WL#709 before.
Reason for the names I propose is to be accurate, thus leaving possibility
for other levels which we may imagine in the future; that's why I have rejected
names like "fast", "smart", "graceful" so far. My position is that WAIT_ALL_BUFFERS
or WAIT_CRITICAL_BUFFERS say what the shutdown does, whereas for "smart", "fast" you
need to remember what it does.
This should be pushed in 4.1.3 but only after your comments.
