Put the flags back in and serialize clusters.
...
Note that now JSON glyph buffers and Unicode buffers look very similar, except for the g/u property difference.

[ragel] Switch to -T1 output instead of -F1
...
Fedora upgraded to ragel 7, which is buggy if char is signed.
Switching to -G2 output fails with sign-compare error:
../../src/hb-buffer-deserialize-json.hh:107:12: error: comparison of integer expressions of different signedness: ‘unsigned int’ and ‘const char’ [-Werror=sign-compare]
if ( 9u <= ( (*( p))) && ( (*( p))) <= 13u ) {
~~~^~~~~~~~~~~~~
Switching to -T1 for now. It actually results in smaller code,
at the expense of some binary searching instead of flat tables.
In the not distant future, we might actually generate two different
outputs and choose between depending on size-optimize options.
