Venus's optimized clib

This page is a work in progress.

I have been working on adding a vlib which will hold most of the functionality of some standard clib functions except that they will be optimized (written in kotlin instead of risc-v while still only using the memory) so that the ops can operate faster. This also allows for me to separate ecall to actually act more of an environment call. To use any of the following functions, you will put 0x3CC in the where register (currently a0 though will eventually be a7). Then you will put in a6 the following to run each vlib function:

ID (a6)	Name	Description
1	malloc	Allocates exactly a1 bytes to the heap. Returns the pointer to that block in a0
2	calloc	Takes in a1 nitems and a2 size of each item. Zeros out the allocated memory. Returns a pointer to that block in a0
3	realloc	Takes in a pointer to the block to realloc in a1 and the new size you want to reallocate to in a2. Returns a pointer in a0 to the newly allocated data. Note if you request a size smaller than the pointer, it will create a new block and copy only size bytes to the new location.
4	free	frees the pointer given in a1. It will merge other free blocks around it if any exist. Does not return anything.
5	num_alloc_blocks	returns to a0 the number of not free blocks or -1 if an error occurred. Errors may involve a modification of the backend structure so a link was not able to be read properly.
