Fixed bug #79683

Reset fake_scope during __toString() call.

I'll check if we can solve this more globally in master, by
resetting fake_scope in zend_call_function.

Fix #74267: segfault with streams and invalid data

If the current character is a line break character, it cannot be a tab
or space character, so we would always fail with an invalid sequence
error. Obviously, these `scan_stat == 4` conditions are meant to be
exclusive.

Furthermore, if `in_pp == NULL || in_left_p == NULL` is true, we hit a
segfault if we are not returning right away. Obviously, the additional
constraints don't make sense, so we remove them.

Fix bug #77966: Cannot alias a method named "namespace"

This is a bit tricky: In this cases we have "namespace as", which
means that we will only recognize "namespace" as an identifier when
the lookahead token is already at the "as". This means that
zend_lex_tstring picks up the wrong identifier.

We solve this by actually assigning the identifier as the semantic
value on the parser stack -- as in almost all cases we will not
actually need the identifier, this is just an (offset, size)
reference, not a copy of the string.

Additionally, we need to teach the lexer feedback mechanism used
by tokenizer TOKEN_PARSE mode to apply feedback to something
other than the very last token. To that purpose we pass through
the token text and check the tokens in reverse order to find the
right one.

Closes GH-5668.

Add $filter parameter for ReflectionClass::(getConstants|getReflectionConstants)

This solves [#79628](https://bugs.php.net/79628).

Similar to `ReflectionClass::getMethods()` and `ReflectionClass::getProperties()`,
this new `$filter` argument allows the filtering of constants defined in a class by
their visibility.

For that, we create three new constants for `ReflectionClassConstant`:

* `IS_PUBLIC`
* `IS_PROTECTED`
* `IS_PRIVATE`

Closes GH-5649.

As its name suggests, `sqlite3_data_count` returns the number of
columns in the current row of the result set; we are interested in the
number of columns regardless of the current row, so we have to use
`sqlite3_column_count` instead.

[RFC] Always enable JSON support in php 8.0

Currently, it's possible to disable the json extension with
`./configure --disable-json` (for historical reasons that no longer apply).
However, JSON is widely used in many use cases - web sites, logging output,
and as a data format that can be used to share data with many applications
and programming languages,
so I'd personally find it useful if it was always enabled.

Examples of where this would be useful:

- For internal classes to be able to implement `JsonSerializable`
which currently requires a hard dependency on the JSON extension.
- For PHP users to publish single-file scripts that use json_encode and
json_decode and don't require polyfills or less readable var_export output.
(polyfills are less efficient and may have issues with recursive data
structures)
- So that php-src's own modules, tools and test cases can start using JSON
if it's a good choice for encoding a value. (same for PECLs)

https://wiki.php.net/rfc/jsond mentions that in PHP 5,

> The current Json Parser in the json extension does not have a free license
> which is a problem for many Linux distros.
> This has been referenced at Bug #63520.
> That results in not packaging json extension in the many Linux distributions.

Starting in php 7.0 with the switch to jsond,
It looks like licensing is no longer an issue.

Changes:

- Remove all flags related to JSON such as `configure --disable-json`
- Require that JSON be compiled statically instead of as a shared library

Examples of uses of JSON in various distros
(backwards incompatible changes such as changing packaging are typically
reserved for major versions, and 8.0 is a major version)

- JSON is required by `php-cli` or `php` in ubuntu:
https://packages.ubuntu.com/focal/php/
- The php-json package has to be installed separately
from the PHP binary in Fedora repos.

Closes GH-5495

Fix several mostly Windows related phpdbg bugs

* Properly initialize PHPDBG_G(watch_tmp)

Otherwise that may cause segfaults in ZTS builds.

* Deactivate potentially remaining watchpoints after REPL

Otherwise the memory could still be protected, resulting in segfaults
during shutdown.

* NULL zend_handlers_table after freeing

As of commit 4130fe4[1], the `zend_handlers_table` is explicitly
freed in the `zend_vm_dtor()`. Since phpdbg (and maybe some other
SAPIs) may restart the engine afterwards, we have to make sure that
the table is also NULLed.

* Only set context option if there is a context

In other words, we must not follow the null pointer.

* Cater to file handles without attached console

File handles do not necessarily have an attached console (for
instance, pipes do not), in which case `GetConsoleScreenBufferInfo()`
fails. In this case we set a default value (`40`) for lines like on
other systems.

Fix #79595: zend_init_fpu() alters FPU precision

On startup, PHP deliberately changes the floating point control word to
enforce binary64 format for the calculations for best consistency
across platforms. However, this is unnessary for x86_64 architectures,
because in this case SSE instructions are used by default, and there is
no good reason to pass `-mfpmath=i387` or such.

Therefore, we can skip the modification, which has the benefit that
system libraries are free to work in the mode of their liking.
