Make USB uart separate from hardware UART

[veremenko-y]

Also make hardware UART fully blocking for kput/kprintf

-extern uint8_t progbase[USERMEM];
+extern char progbase[USERMEM];

This seems to be unrelated and strange ?

Rest looks ok but please try and use (void) not () for no arg functions. The PI compiler doesn't care but no some targets there is a difference between "no arguments" and "K&R style who knows arguments"

Ack. I'll go though the patch to ensure it doesn't happen again. Do you want me to add this to the CodingStyle.md? (which I realized I haven't read, but it does missing the foo(void)).

This was part of fighting the compiler and conflicting types. I'll check this first and remove if unnecessary.

Both issues should be addressed now.
