* Rename several dCamera_c fields
* Refactor mWork to generic buffer instead of union
* d_camera match improvements
* Implement several dCamera_c functions
* Remove d_camera.h from PCH
The symbol names in d_camera indicate that this header wasn't
included in the PCH (as they're compiled directly in d_camera.cpp).
* Fix debug build
* Debug build now takes .alf as input instead of .dol
I had to manually remove the following line from symbols.txt for DTK to work:
```
.data = .sbss:0x8074C97C; // type:object size:0x4 scope:local data:byte
```
After that it built OK, and DTK automatically modified all other lines in symbols.txt.
* Fix pragma in header messing up debug optimization level
