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
