socz80: ramtop has changed type

Start bringing socz80 back into line
socz80: config.h updates
socz80: start reworking MMU code for 16K banking model

Bank switching functions, and switchin/switchout looked at so far. The fork
copying code remains to be done. Here it definitely makes sense to use the
MMU page 17 logic, but we now need to do it in 16K chunks.
syscall: correct arg descriptions in uname
syscall_proc: change _time to allow multiple kinds of time

Add since boot monotomic time.

Yes this is an ABI break....
syscall_name: add argument counts to the tables

We will need these to automate creation of some types of call stubs
time: resynch library with API change for time()

Better to do this before we have too many dependancies than to delay it
until we can't change it.
chmem: Update for new format binaries
crt0: Add a byte for the base of the binary

Next step in the ABI breaking changes
execve: change binary format, add a byte for bank base and align fields
time: correct bug, add stime time type

This finishes the basic provision for multiple time sources
syscalls: extra argument for _stime()
syscall uname: Add the uptime data

While are breaking the prototype ABI lets just stuff the uptime data in
the sysinfo block and be done with it.
z88dk: Add first pieces to bootstrap Z88DK for Fuzix
Correct spelling of LICENCE. This is a UK based project so there
