Check if tablespace name is valid
@param tablespace_name Name of the tablespace
@note Tablespace names are not reflected in the file system, so
character case conversion or consideration is not relevant.
@note Checking for path characters or ending space is not done.
The only checks are for identifier length, both in terms of
number of characters and number of bytes.
@retval IDENT_NAME_OK Identifier name is ok (Success)
@retval IDENT_NAME_WRONG Identifier name is wrong, if length == 0
* (ER_WRONG_TABLESPACE_NAME)
@retval IDENT_NAME_TOO_LONG Identifier name is too long if it is greater
than 64 characters (ER_TOO_LONG_IDENT)
@note In case of IDENT_NAME_TOO_LONG or IDENT_NAME_WRONG, the function
reports an error (using my_error()).
