Update all source files to use uintN_t

[ghost]

The data types used in goodfet files are of 3 kinds:

-stdint ones (uint8_t, etc)
-normal C ones (unsigned char, etc)
-some more (u8, etc)

My proposition is to use stdint types in every file.

Is there anything unknown to me that would prevent doing that?

Nothing prevents it, but be very careful not to damage any code that you don't have the hardware to test. One mistaken regex could break support for a rare module, and it wouldn't be noticed for months.
