Change PandaSet to be consistent with other types.
Remove ssize_t (and unistd.h) from public API.
Fix ref/unref attributes and compact class attributes in Vala binding
Remove ssize_t from main.c
Fixed bug in non-pthreaded buffer allocation
Various lint fixes
Introduced PANDA_NT_Z and cleaned up IUPAC lists
Remove splint annotations and change indent parameters

Splint never seemed to work right with unistd.h, so it's just easier to
rip it all out, which is unfortunate. Without splint annotations, the
indent can be adjusted to do more sensible things.
