Added vfs_create() to create files and directories.
...
Moved mkdir to mknod so that mknod is the common handler for all node creation.

Fixed lookup return value. Now using generic_lookup directy, i.e.
...
not through a vnode, because it really isn't fs-specific.

Implemented vfs_lookup_byvnum() close to what it should look like.

sys_readdir and memfs_readdir closer to targeted look and feel.
...
We now have a single dirbuf of size PAGE_SIZE kept on the vnode. This is
to be used for directory contents only. The reason it's kept on FS0 is
because the contents are modified by calls such as mkdir or create, and otherwise
these would have been handled by mm0 on the page cache buffers, which wouldn't work.

Some preliminary efforts to reading directory contents in fs0.
...
Need to still decide whether content buffers are provided by mm0,
whether need to return them back to mm0, and the read count.

swapped write_mr() arguments.
...
write_mr() now works as write_mr(mr_offset, mr_val), which makes sense.
