The generic filesystem interface was so far untested. The interface is similar to the FS specific interfaces with FS specific prefixes, like ext4ls, fatmkdir, ... but it does not have any prefixes, i.e. it provides plain ls, mkdir, ... commands. Extend the test parameters to include 'fs_cmd_prefix' and optionally 'fs_cmd_write' parameters. The 'fs_cmd_prefix' allow specifying the filesystem specific command prefix, like 'ext4' in 'ext4ls'. The 'fs_cmd_write' allows selecting between 'write'/'save' command name for storing files into the filesystem, see last paragraph. Introduce new 'fs_generic' fs_type which is used to parametrize existing tests and run them without any prefixes if detected, thus testing the generic filesystem interface. Use the fatfs as the backing store for the generic FS tests. The check_ubconfig needs to be slightly adjusted to avoid test for CMD_FS_GENERIC_WRITE which does not exist separately from CMD_FS_GENERIC. The CMD_FS_GENERIC does not provide generic 'write' command, instead the generic equivalent command is called 'save' . Add simple ternary oeprator to use 'save' command for CMD_FS_GENERIC tests and '..write' commands for filesystem specific tests. Enable generic filesystem tests for basic/extended/mkdir/unlink tests.
