Reformat symbol table

Using function calls instead of one big object literal for the symbols makes
the notation far more concise and readable.  Having the actual symbol name
in the last position helps aligning the preceding columns, making the list
easier to read.

Another benefit is that all symbol definitions now pass through a single
function, where additional processing (e.g. for Unicode input) might take
place in a future commit.
