FastCFS v3.7.1 发布，支持用户附加组

FastCFS v3.7.1发布，支持用户附加组，完全符合POSIX标准，解决了在FastCFS的fuse client上跑NFS（套娃模式）可能碰到的访问权限问题。

v3.7.1改进和修复的问题如下：

• [fdir] service_stat add fields: version, auth_enabled and storage_engine
• [fdir] list dentry support special dentries . and ..
• [fdir] call get_path_block_size only when read_direct_io is true
• [fdir] dentry_remove bugfixed: correct posix ACL check
• [fstore] service_stat add version field and support options: -G and all
• [libserverframe] check socket connected on unexpected stage
• [libserverframe] get_leader_connection: failover on multi ip addresses
• [libserverframe] change log level to debug for hash entry reclaim
• [libfastcommon] parse_bytes support space charactors (before and after the unit)
• [libfastcommon] fc_fallocate fail back to ftruncate under Linux

FastCFS 为intel和arm架构分别提供了 rpm 和 deb 包，欢迎大家安装和体验。
