700c3b1d1b Move implementation files into their own folder
main.c and test.c generate binary executables so they can stay in the
main folder, but the rest can go into their own dedicated folder to
make it look nicer

847eb1a69b Refactor vectors to SBO, removing inlined entirely.
Avoid 2 levels of indirection, and having to allocate twice for small
payloads, by having an inlined array on the vector directly!
Beautiful and simple.

Required a bit of refactoring around the board, but overall the result
makes me feel happier.

13142dc7f3 refactor lisp runtime to use vec_t* instead of ivec_t*
bit nicer to look at, should have about the same painful performance
hit anyway.

df558da7e1 Use sv_t instead of raw char*
We're storing them as sv_t's anyway, we're fucked with regards to
indirection.  Thus, let's be nice to ourselves, and deal with the
structures.  We get the size of the structure for free anyway!

643896e2c8 rename base.h -> alisp.h
Makes more sense when you think about including it as an external
library

3074ba5bab Constructors and context -> sys
We can register memory we've allocated onto the heap into a ~sys_t~
instance for examination (read: garbage collection) later.  We can
also add items to the symbol table it has internally.

779c4b8305 Conses and Vectors for my tagging scheme
Unfortunately, due to how vectors are implemented, pointers to them
are unstable.  We need to box them one more time (therefore adding a
level of indirection) in order to stabilise them.  This is annoying
but currently necessary.

Even if we implemented vectors as {u64, u64, ptr} instead of {u64,
u64, bytes...}, we'd still have the same problem at access - two
levels of indirection.  I guess size and capacity checks would be one
level of indirection which is nice at least, but we're already screwed
at the point of doing lookup either way.

7ac2a80b11 Pointer tagging!
Copied from oats, just the basics required for tagging integers or
symbols.
