  qom: Do not reuse errp after a possible error

The argument for an Error **errp parameter must point to a null
pointer.  If it doesn't, and an error happens, error_set() fails its
assertion.

Instead of

    foo(foos, errp);
    bar(bars, errp);

you need to do something like

    Error *err = NULL;

    foo(foos, &err);
    if (err) {
  error_propagate(errp, err);
  goto out;
    }

    bar(bars, errp);
out:

Screwed up in commit 0e55884 (v1.3.0): property_get_bool().

Screwed up in commit 1f21772 (v2.1.0): object_property_get_enum() and
object_property_get_uint16List().

Screwed up in commit a8e3fbe (v2.4.0): property_get_enum(),
property_set_enum().

Found by inspection, no actual crashes observed.

Fix them up.

  qom: Fix invalid error check in property_get_str()

When a function returns a null pointer on error and only on error, you
can do

    if (!foo(foos, errp)) {
  ... handle error ...
    }

instead of the more cumbersome

    Error *err = NULL;

    if (!foo(foos, &err)) {
  error_propagate(errp, err);
  ... handle error ...
    }

A StringProperty's getter, however, may return null on success!  We
then fail to call visit_type_str().

Screwed up in 6a146eb, v1.1.

Fails tests/qom-test in my current, heavily hacked QAPI branch.  No
reproducer for master known (but I didn't look hard).

  qdev: Do not use slow [*] expansion for GPIO creation

Expansion of [*] suffix is very slow because index expansion is done using
trial and error strategy, starting every time from zero and retrying with
the next index until insertion succeeds. With large number of already added
properties this process takes huge amount of time (O(n^2) complexity).

Some architectures (like ARM) use very large amount of IRQ pins in interrupt
controller models. This flaw makes machine startup extremely slow
(~20 seconds for ARM64 with 32 CPUs). This patch decreases this time down to
~10 seconds.

Also in qdev_init_gpio_out_named() memset() is now called only once for the
whole array instead of per-cell cleaning
