In addition adjust the logic so we build a correctly parsed last name component

This gets rid of filename() which saves us copying and parsing the path twice
as well as getting rid of that code
It gets rid of most of the 30 byte name arrays (rename still has to have one)
It allows us to get rid of ugets()
Our PATH_MAX can now be arbitrarily set (for now still 512)
ugets/_ugets/__ugets all go away
pathbuf for LEVEL2 goes away, LEVEL0 and 1 and 2 now all look the same

kernel: restructure readi/writei to save memory
This saves us 256 bytes on Z80 mostly by removing the amount of 32bit maths
SDCC has the opportunity to **** up.
We introduce a helper (umove) which adjusts all the pointers and offsets
for a given file and use that where we can. We also restructure a bit so we
can use the udata.u_done value in readi/writei
This has some minor consequences:
Callers need to check u_done for completion not u_count
Char and Socket handlers don't affect the offset unless they choose to (which
is saner). Devsys has been modified accordingly.
Handle with care.
