/*
Reassign all tables assigned to a key cache to another key cache
SYNOPSIS
reassign_keycache_tables()
thd Thread object
src_cache Reference to the key cache to clean up
dest_cache New key cache
NOTES
This is called when one sets a key cache size to zero, in which
case we have to move the tables associated to this key cache to
the "default" one.
One has to ensure that one never calls this function while
some other thread is changing the key cache. This is assured by
the caller setting src_cache->in_init before calling this function.
We don't delete the old key cache as there may still be pointers pointing
to it for a while after this function returns.
RETURN VALUES
0 ok
