Kernel+SystemMonitor: Log amounts of I/O per thread

Browse source 
This patch adds these I/O counters to each thread:

- (Inode) file read bytes
- (Inode) file write bytes
- Unix socket read bytes
- Unix socket write bytes
- IPv4 socket read bytes
- IPv4 socket write bytes

These are then exposed in /proc/all and seen in SystemMonitor.
