It's the same as (int) zend_atol() -- it doesn't try to do anything
integer size specific. Canonicalize to one function in preparation
for renaming zend_atol() to something less misleading.
FFI test is adjusted to use a zend_test function. It just calls
zend_atol() internally, but could really be anything.

1. Update: http://www.php.net/license/3_01.txt to https, as there is anyway server header "Location:" to https.
2. Update few license 3.0 to 3.01 as 3.0 states "php 5.1.1, 4.1.1, and earlier".
3. In some license comments is "at through the world-wide-web" while most is without "at", so deleted.

As these hold on to some internal resource, there can't be two
"equal" objects with different identity. Make sure the lack of
public properties doesn't result in these being treated as always
equal.
This deprecates passing null to non-nullable scale arguments of
internal functions, with the eventual goal of making the behavior
consistent with userland functions, where null is never accepted
for non-nullable arguments.
This change is expected to cause quite a lot of fallout. In most
cases, calling code should be adjusted to avoid passing null. In
some cases, PHP should be adjusted to make some function arguments
nullable. I have already fixed a number of functions before landing
this, but feel free to file a bug if you encounter a function that
doesn't accept null, but probably should. (The rule of thumb for
this to be applicable is that the function must have special behavior
for 0 or "", which is distinct from the natural behavior of the
parameter.)

We're starting to see a mix between uses of zend_bool and bool.
Replace all usages with the standard bool type everywhere.
Of course, zend_bool is retained as an alias.
When `php_zlib_deflate_filter()` is called with `PSFS_FLAG_FLUSH_INC`
but without new buckets being available (e.g. because a user calls
`rewind()` after writing to the stream), we have to make sure that any
pending data are flushed. This could basically be done like in the
attached patch[1], but that could cause unnessary flushes, which can be
harmful for compression, and adds unnecessary flush markers to the
stream. Thus, we use the `php_zlib_filter_data.finished` field, which
has not been used for `zlib.deflate` filters, and properly keep track
of the need to flush.

Closes GH-6019.
Reading from a stream may return greater than zero, but nonetheless the
stream's EOF flag may have been set. We have to cater to this
condition by setting the close flag for filters.
We also have to cater to that change in the zlib.inflate filter:
If `inflate()` is called with flush mode `Z_FINISH`, but the output
buffer is not large enough to inflate all available data, it fails with
`Z_BUF_ERROR`. However, `Z_BUF_ERROR` is not fatal; in fact, the zlib
manual states: "If deflate returns with Z_OK or Z_BUF_ERROR, this
function must be called again with Z_FINISH and more output space
(updated avail_out) but no more input data, until it returns with
Z_STREAM_END or an error." Hence, we do so.
Closes GH-6001.
While performing resource -> object migrations, we're adding
defensive classes that are final, non-serializable and non-clonable
(unless they are, of course). This path adds a ZEND_ACC_NO_DYNAMIC_PROPERTIES
flag, that also forbids the creation of dynamic properties on these objects.
This is a subset of #3931 and targeted at internal usage only
(though may be extended to userland at some point in the future).
It's already possible to achieve this (what the removed
WeakRef/WeakMap code does), but there's some caveats: First, this
simple approach is only possible if the class has no declared
properties, otherwise it's necessary to special-case those
properties. Second, it's easy to make it overly strict, e.g. by
forbidding isset($obj->prop) as well. And finally, it requires a
lot of boilerplate code for each class.
Closes GH-5572.
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.
Closes GH-5353. From now on, PHP will have reflection information
about default values of parameters of internal functions.

The php_stream_read() and php_stream_write() functions now return
an ssize_t value, with negative results indicating failure. Functions
like fread() and fwrite() will return false in that case.
As a special case, EWOULDBLOCK and EAGAIN on non-blocking streams
should not be regarded as error conditions, and be reported as
successful zero-length reads/writes instead. The handling of EINTR
remains unclear and is internally inconsistent (e.g. some code-paths
will automatically retry on EINTR, while some won't).
I'm landing this now to make sure the stream wrapper ops API changes
make it into 7.4 -- however, if the user-facing changes turn out to
be problematic we have the option of clamping negative returns to
zero in php_stream_read() and php_stream_write() to restore the
old behavior in a relatively non-intrusive manner.

And convert some object to string conversion related recoverable
fatal errors into Error exceptions.
Improve exception safety of internal code performing string
conversions.
Normalization include:
- Use dnl for everything that can be ommitted when configure is built in
favor of the shell comment character # which is visible in the output.
- Line length normalized to 80 columns
- Dots for most of the one line sentences
- Macro definitions include similar pattern header comments now
