[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.

Add support for * width and precision in printf()

If * is used for width/precision in printf, then the width/precision
is provided by a printf argument instead of being part of the format
string. Semantics generally match those of printf in C.

This can be used to easily reproduce PHP's float printing behavior:

// Locale-sensitive using precision ini setting.
// Used prior to PHP 8.0.
sprintf("%.*G", (int) ini_get('precision'), $float);

// Locale-insensitive using precision ini setting.
// Used since to PHP 8.0.
sprintf("%.*H", (int) ini_get('precision'), $float);

// Locale-insensitive using serialize_precision ini setting.
// Used in serialize(), json_encode() etc.
sprintf("%.*H", (int) ini_get('serialize_precision'), $float);

Closes GH-5432.

PGSQL and POD_SQL: don't include pg_config.h

Even if that header file is available, we better consider it private,
and don't include it. The information about whether SSL support is
enabled is now missing (`USE_(OPEN)SSL`), and it seems there is no
alternative way to get it (`PQinitSSL()` is always defined), so we
remove it from the PHP info. Furthermore, the `PG_VERSION` and
`PG_VERSION_STR` macros are no longer available, but as of libpq 9.1
there is `PQlibVersion()` which allows us to construct `PG_VERSION` in
a most likely backwards compatible manner. The additional information
available through `PG_VERSION_STR` is lost, though, so we define
`PGSQL_LIBPQ_VERSION_STR` basically as alias of `PGSQL_LIBPQ_VERSION`,
and deprecate it right away.

Since we are now requiring at least libpq 9.1, we can remove some
further compatibility code and additional checks.

Regarding the raised requirements: official support for PostGreSQL 9.0
ended on 2015-10-08, and even CentOS 7 already has PostGreSQL 9.2, so
this is not supposed to be too much of an issue.

Deprecate old ReflectionParameter type declaration APIs

This deprecates:

ReflectionParameter::isArray()
ReflectionParameter::isCallable()
ReflectionParameter::getClass()

These APIs have been superseded by ReflectionParameter::getType()
since PHP 7.0. Types introduced since that time are not available
through the old APIs, and their behavior is getting increasingly
confusing. This is how they interact with PHP 8 union types:

* isArray() will return true if the type is array or ?array,
but not any other union type
* Same for isCallable().
* getClass() will return a class for T|int etc, as long as the
union only contains a single type. T1|T2 will return null.

This behavior is not particularly reasonable or useful, and will
get more confusing as new type system extensions are added.

Closes GH-5209.
