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\_allow\_pid - allow another process to map a shareable buffer
## Synopsis
```**c++
#include <SharedBuffer.h>
int shbuf_allow_pid(int shbuf_id, pid_t peer_pid);
```
## Description
Gives the process with PID `peer_pid` permission to map the shareable buffer with ID `shbuf_id`.
## Return value
On success, returns 0. Otherwise, returns -1 and `errno` is set.
## Errors
* `EINVAL`: `peer_pid` is invalid, or `shbuf_id` is not a valid ID.
* `EPERM`: The calling process does not have access to the buffer with `shbuf_id`.
* `ESRCH`: No process with PID `peer_pid` is found.
