Feature changes

- APC storage handler update

  - Fix build for APC 3.1.9+
  - Note: Use of the APC storage handler is currently not recommended due to stability issues of APC itself.

- New PHP configuration directives

  - mysqlnd_qc.collect_statistics_log_file. Aggregated cache statistics log file written after every 10th request served by the PHP process.
  - mysqlnd_qc.ignore_sql_comments. Control whether SQL comments are ignored for cache key hash generation.

- New constants and SQL hints

  - `MYSQLND_QC_SERVER_ID_SWITCH` allows grouping of cache entries from different physical connections. This is needed by PECL/mysqlnd_ms.
  - `MYSQLND_QC_CONDITION_META_SCHEMA_PATTERN` to be used with mysqlnd_qc_set_cache_condition.

- New function mysqlnd_qc_set_cache_condition for built-in schema pattern based caching. Likely to support a wider range of conditions in the future.

- Report valid_until timestamp for cache entries of the default handler through mysqlnd_qc_get_cache_info.

- Include charset number for cache entry hashing. This should prevent serving result sets which have the wrong charset.

  API change: get_hash_key expects new "charsetnr" (int) parameter after "port".

- API change: changing is_select() signature from bool is_select() to mixed is_select(). Mixed can be either boolean or array(long ttl, string server_id). This is needed by PECL/mysqlnd_ms.

Other

- Support acting as a cache backend for PECL/mysqlnd_ms 1.3.0-beta or later to transparently replace MySQL Replication slave reads with cache accesses, if the user explicitly allows.

Bug fixes

- Fixed Bug #59959 (config.m4, wrong library - 64bit memcached handler builds) (Credits: Remi Collet)
