07458f62dd Support non-BMP characters for synthetic glyph names 
When a font supplies no glyph names in its 'post' table, fontTools
builds synthetic glyph names by reversing the 'cmap' table.
After this change, the library looks at all 'cmap' subtables for
Unicode, irrespective of format or platform. For example, glyph #4
in NotoSansOldItalic-Regular.ttf gets now named "u10300" instead of
"glyph00004".

Moved the code for building a reversed 'cmap' table into the cmap class,
for easier testing.

e05db5c75f [_c_m_a_p] fix compiling of cmap subtable format 6 
Fixes https://github.com/googlefonts/fontbakery/issues/551

the `codes` variable needs to be a sorted list of cmap keys, else the following line
```python
codes = range(codes[0], codes[-1] + 1)
```
cannot work properly, since dict keys are unsorted.

Up until 13a08d0c3a59402459875155b7dbd194787fb229, there was a line with
```python
codes.sort()
```
which was deleted for some reason.

c7b6d1943d Fix decompiling of cmap table 
Previously, if a subtable's data was shared amongst two different encodings,
the second one being loaded was getting a cmap member assigned while retaining
its data item.  If we subset the cmap and then save that subtable, the original
unsubset data will be written out.  Fix, but removing data when assigning cmap.

Explains and obviates mystery hack in subsetter.

This codepath never worked, and is never exercised during normal operations.

4e616d2f7f Accept MS Symbol cmap tables as Unicode-compatible 
Apparently these days these tables are used to encode symbols in
PUA, so they are still Unicode-compatible...

This follows a similar change in fontconfig.

1a4f96b787 Remove total_ordering 
Upon studying further, we don't need it.  Since we only expect
comparing objects of the same type, just having __lt__ is enough.

9e6ef94b55 Use "is None" instead of "== None" 
The latter hits the __eq__ method and can fail because we now
do not allow comparing objects of different types.

For example, was failing subsetting Andika-R.ttf.
