kernel: Rename basic "int" functions to "interrupt" (or at least "intr").

"int" of course is also an abbrevation for "integer", so having
two abbreviations is sometimes confusing. The BeOS functions
just use "interrupt" (e.g. "install_io_interrupt_handler"); it
seems we inherited the "int" abbreviation from NewOS.

The basic kernel methods and files related to interrupts are
here adjusted to drop the abbreviation and just use "interrupt(s)".
The architecture-specific functions ("arch_int_*") are mostly
moment left alone for now, though of course architecture-specific
usages of the generic kernel methods are adjusted.
