Add Ed25519-compatible generator point
...
The old point is renamed, as it isn't the only default point anymore. The
old name and functions using the old point are deprecated now.

Fix loading of packed points in edge case

The parity bit was not handled correctly when the squeezed value of Y is
not fully reduced.

Use stdint types where reasonable
...
Using uint32_t instead of unsigned int for the unpacked work struct ensures
the code is working correctly on ABIs with ints narrower than 32 bits.
While this would constitute a API/ABI change on some systems in theory,
most likely all systems using libuecc so far have uint8_t == unsigned char
and uint32_t == unsigned int.
Also, coding style cleanup.

Remove some unnecessary squeeze() calls
...
As only the subtrahend in a sub() call needs to be squeezed, the squeeze
can be skipped in these cases.

Move documentation comments for public API to the public header
...
This makes the documentation more accessible, as the header now contains
all information regarding the usage of the API, and it is not necessary to
generate the Doxygen documentation anymore for that.

Switch from inverted to extended coordinate representation
...
In inverted coordinates there are 4 points that aren't representable correctly. Avoid this problem by using the extended coordinate representation, in which an add+double operation has essentially the same performance as in the inverted representation.
