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().

Ned Bass 410d8c4e15 Reduce dsl_scan_visitbp stack usage by moving blkptr_t to heap 
Github issue 22 reported a stack overrun when the zfs module was
loaded, possibly related to the presence of existing zpools created
under zfs-fuse.  The stack trace showed 9 levels of recursion between
dsl_scan_visitbp() and dsl_scan_recurse(). To reduce stack overhead in
that code path, this commit moves the 128 byte blkptr_t data strucutre
in dsl_scan_visitbp() to the heap.

Ned Bass d5658668e0 Reduce stack usage of zio_done 
Eliminated local variables pointing to members of the zio struct.
Just refer to the struct members directly.  This saved about 32 bytes per
call, but this function can be called recurisvely up to 19 levels deep,
so we potentially save up to 608 bytes.

Moving the vdev_cache_entry_t struct ve_search from the stack to
the heap saves ~100 bytes.
