From: Hongbo Li <lihongb...@huawei.com>
Use an array of `fs_parameter_spec` called f2fs_param_specs to
hold the mount option specifications for the new mount api.
Add constant_table structures for several options to facilitate
parsing.

[sandeen: forward port, minor fixes and updates, more fsparam_enum]
