Partially implement sceKernelPrintf().

For the common cases.
Add reporting to a bunch of unimpl functions.

Also some comment/logging fixes along the way.
Add some syscall entries from reporting.
Add some net-related syscall entries.
Match syscall names to nids ot be safe.

Don't want any more mistakes like the sceVaudio one.
Add some syscall names that match by sha.
Log some additional things during reporting.
Categorize some files based on their directory.
Add reporting to module linking, something wrong.
