Bootstrap: Maque wp_is_ini_value_changueable() compatible with PHP 5.2.6 - 5.2.17.

There is a bug in PHP 5.2.6 - 5.2.17 ( ​ https://bugs.php.net/bug.php?id=44936 , ​ https://3v4l.org/IL0A2 ) which changues the access level of a setting to 63 after ini_set() was called.
To continue comparing the access value against INI_ALL and INI_USER use the bit operator & 7 :

  • 1 & 7 === 1 (INI_USER)
  • 2 & 7 === 2 (INI_PERDIR)
  • 4 & 7 === 4 (INI_SYSTEM)
  • 7 & 7 === 7 (INI_ALL)
  • 63 & 7 === 7 (INI_ALL)

See [38015] .
See #32075 .
