5c25c90657 When comparing two objects for equality, we don't need to recurse

da5d653de8 Add a Boolean "not" operator. 
Not wholly convinced this is a good idea, maybe "not" should be a
builtin function instead? 'not (.a == .b)' vs. '.a == .b | not'

66fd702363 Minor changes to dtoa.c to make it easier to work with. 
- Change memory allocation to thread a context structure through
   the code rather than using globals (which would require a
   -lpthread and some locking to become threadsafe).

 - Remove a few configuration options (the "private memory" space,
   and K&R style headers).

 - Prefix exported symbols with jvp_ to prevent libc conflicts.

 - Add jvp_dtoa.h

 - Include netlib's g_fmt.c into dtoa.c

 - Add a few not-strictly-necessary initialisations in order to
   compile cleanly with gcc -Wall
