Brian Behlendorf 52c23142d4 Revert "Inline zio_execute() to reduce stack use" 
This reverts commit 411dd65af1.

gcc version 4.1.2 does not like having differing prototypes
for zio_execute, one version in the .c with inline and one
version in the .h without.  Thus I'm reverting this change
and we'll see how critical this particular stack reduction is.

Ned Bass 4d3fc57112 Reduce stack usage for recursive dbuf_hold_impl() 
This commit preserves the recursive function dbuf_hold_impl() but moves
the local variables and function arguments to the heap to minimize
the stack frame size.  Enough space is initially allocated on the
stack for 20 levels of recursion.  This technique was based on commit
34229a2f2a which reduced stack usage of
traverse_visitbp().

dbuf_hold_impl() is mutually recursive with dbuf_findbp(),
but the latter function is also called from other functions.
Therefore dbuf_findbp() must contain logic to determine how to call
dbuf_hold_impl().  To this end, dbuf_hold_impl() now takes a
struct dbuf_hold_impl_data pointer as an argument.  If that argument
is NULL it calls dbuf_hold_impl() as before, otherwise it calls
__debuf_hold_impl() with a single dbuf_hold_impl_data pointer argument.
As the name implies, dbuf_hold_impl_data stores the arguments and local
variables for dbuf_hold_impl().
