This syncs the installed sapi and extension headers on *nix and Windows
systems by installing only what is intended outside of php-src.
- ext/gd: without gd_arginfo.h and gd_compat.h
- ext/hash: php_hash_joaat.h and php_hash_fnv.h added also on Windows
installation; xxhash/xxhash.h added on both installations as it is
included in php_hash_xxhash.h; Include path for xxhash.h changed to
relative so the php_hash_xxhash.h can be included outside of php-src;
Redundant include flags removed
- ext/iconv: without iconv_arginfo.h
- ext/mysqli: mysqli_mysqlnd.h was missing on Windows
- ext/phar: php_phar.h was missing on Windows
- ext/sodium: php_libsodium.h was missing on *nix
- ext/xml: without xml_arginfo.h
- sapi/cli: cli.h was missing on Windows
