Little conventions that are used that make the code easier to follow. Break them when appropriate.

• If using noise as a library, you only need to #include "noise.h".
• All extern symbols are prefixed with nz_ to facilitate including as a library.
• An rsprintf function is used to allocate memory for a formatted string (like asprintf, with a different API)
• Error handling
  • If a function can error, it either returns a pointer or an int
  • On error, it returns either NULL or -1 respectively, such that errno is set appropriately
    • System & lib calls (e.g. calloc) will set errno, no need to re-set
  • (Functions which test something and return a boolean will return 0 for false, and 1 for true!)
• const pointers when possible, as in const char * mystr, but not like char * const mystr or const char * const mystr.
• Carefully document when pointer ownership transfers! It should be very obvious from signature/name.
• OOP-y data:
  • Preference for int xxx_init(struct xxx *, ...) and void xxx_term(struct xxx *) functions, which initialize & deinitialize an already-allocated struct.
  • For opaque structs, use struct xxx * xxx_create(...) and void xxx_destroy(struct xxx *) functions.
  • structs have members in the form struct nz_xxx { int xxx_yyy; ... } to make code infinitely more greppable
• Dealing with pointers to structs is nice, but so is having them on the stack. struct xxx x[1]; solves this, making x be accessible as (almost) a struct xxx *. Save on &'s!
