logging

[aenachescu]

Create a library for logging and use it instead of kprintf. What it should offer:

• more logging levels: fatal, error, warning, info, trace
• info about file (relative to PhiOS folder (see FILENAME)) and line
• send logs to multiple terminal: vga text mode, serial, usb etc
• use printf format (preferably completely)

E.g: KLOG_ERROR("here it's a big error: %u", err); ==> [kernel/src/arch/x86/init32.c] [115] [ERROR] - here it's a big error: 5
