Kernel+LibC: Rename shared buffer syscalls to use a prefix

Browse source 
This feels a lot more consistent and Unixy:

    create_shared_buffer()   => shbuf_create()
    share_buffer_with()      => shbuf_allow_pid()
    share_buffer_globally()  => shbuf_allow_all()
    get_shared_buffer()      => shbuf_get()
    release_shared_buffer()  => shbuf_release()
    seal_shared_buffer()     => shbuf_seal()
    get_shared_buffer_size() => shbuf_get_size()

Also, "shared_buffer_id" is shortened to "shbuf_id" all around.

## Name
shbuf\_create - create a shareable memory buffer
## Synopsis
```**c++
#include <SharedBuffer.h>
int shbuf_create(int size, void** buffer);
```
## Description
Creates a new memory region that can be shared with other processes. The region is only accessible to the calling process by default.
## Return value
If a region is successfully created, `shbuf_create()` stores a pointer to the memory in `buffer` and returns a buffer ID. Otherwise, it returns -1 and sets `errno` to describe the error.
## Errors
* `EINVAL`: `size` is zero or negative.
* `EFAULT`: `buffer` is not a valid address.
