e07eeab043 Make yield a regular syscall taking an argument. 
Allows "wait for interrupt"/"wait for event" type operation where VM code blocks until the host has something for it.

76fba39a21 Rework syscall ABI. 
Syscalls now accept two parameters, allowing for things like "int count = read(buf, len)"
Rather than providing safe signatures for syscalls, the user is now given helper functions to safely parse incoming values, c-strings and slices.

ee2ba56423 Add cmdline option to host <file.bin> [max_instrs_to_run], to set instruction meter. 
Allow a host to continue after a hung error, if it wants to.

So, a program with while(1) {} can be run indefinitely.
