bpo-29591: Upgrade Modules/expat to libexpat 2.2 (#2164)
* bpo-29591: Upgrade Modules/expat to libexpat 2.2 * bpo-29591: Restore Python changes on expat * bpo-29591: Remove expat config of unsupported platforms Remove the configuration (Modules/expat/*config.h) of unsupported platforms: * Amiga * MacOS Classic on PPC32 * Open Watcom * bpo-29591: Remove useless XML_HAS_SET_HASH_SALT The XML_HAS_SET_HASH_SALT define of Modules/expat/expat.h became useless since our local expat copy was upgrade to expat 2.1 (it's now expat 2.2.0).
