If `SQLPutData()` *fails*, we should not call `SQLParamData()` again,
because that yields the confusing `HY010` (Function sequence error).
Instead we properly handle `SQLPutData()` errors.
For the given case (paramter length > column length), some drivers let
`SQLPutData()` fail, while others do not. Either behavior seems to
conform to the ODBC specification. Anyhow, we do not want to silently
truncate the given parameter, since that would break the behavior for
drivers which do not fail, but still don't simply truncate the given
parameter. So it is finally up to userland to avoid passing overlong
parameters – with this patch they at least get useful information about
the actual issue.
Closes GH-9541.
When traversing the result array, we need to cater to `param_name`
possibly being `NULL`. Prior to PHP 7.0.0, this was implicitly done
because `param_name` was of type `char*`.

The fix for bug 63327[1] changed the extra size of mysqlnd allocations
from `sizeof(size_t)` to the properly aligned values; however, the
allocation in `_mysqlnd_pestrdup()` has apparently been overlooked,
which (currently) causes detectable heap corruption when running
mysqli_get_client_stats.phpt on 32bit Windows versions.

As of PHP 8.2.0, `zend_module_entry` structures are no longer copied,
so when a module is permanently loaded, and users try to dynamically
load that module again, the structure is corrupted[1], causing a
segfault on shutdown.
We catch that by checking whether any dynamically loaded module is
already loaded, and bailing out in that case without modifying the
`zend_module_entry` structure.

Changing indirect call to direct call for Jit code
benefits the branch prediction, which gets 1% performance
gain in our workload.
Similarly, we change indirect jump to direct jump.

Previously, notify would only get called on classes with CE_CACHE.
However, during compilation class names are non-permanent which won't
get a CE_CACHE and thus wouldn't not get notified.
Closes GH-9550
