Add two string git_buf_join and tweak input error checking. This commit addresses two of the comments: * renamed existing n-input git_buf_join to git_buf_join_n * added new git_buf_join that always takes two inputs * moved some parameter error checking to asserts * extended unit tests to cover new version of git_buf_join
