The hash is used to check whether the arginfo file needs to be
regenerated. PHP-Parser will only be downloaded if this is actually
necessary.
This ensures that release artifacts will never try to regenerate
stubs and thus fetch PHP-Parser, as long as you do not modify any
files.
Closes GH-5739.
The (void)_dummy is apparently considered a read of an uninitialized
variable. As it is a _Bool now, which has trap representations, this
is no longer considered legal and results in somewhat odd ubsan
warnings of the form:
runtime error: load of value 0, which is not a valid value for type 'zend_bool' (aka 'bool')
Exception should be thrown before the db handle is destroyed.

Closes GH-5353. From now on, PHP will have reflection information
about default values of parameters of internal functions.

The fix for feature request #53466 did not properly handle resetting of
the corresponding statement; the problem with this is that the
statement does not know about its result sets. But even if we could
fix this, the `complete` handling still appears to be brittle, since
the `sqlite3_column_type()`docs[1] state:
| If the SQL statement does not currently point to a valid row, or if
| the column index is out of range, the result is undefined.
Fortunately, we can use `sqlite3_data_count()` instead, since[2]:
| If prepared statement P does not have results ready to return (via
| calls to the sqlite3_column() family of interfaces) then
| sqlite3_data_count(P) returns 0.
Thus, we guard `SQLite3::columnType()` with `sqlite3_data_count()`, and
completely drop updating the `php_sqlite3_result_object.complete`
field, but keep it for ABI BC purposes.

Since we're passing these parameter to C functions accepting `char*`
without any further checking, we should reject strings with NUL bytes
in the first place.
Since `zend_parse_parameters()` now throws on failure, it doesn't make
sense anymore to use `zend_parse_parameters_throw()` instead, and also
it's useless to set an explicit return value.
