Fix test_simple_rw_reg.test_illegal_address so that it always recognizes issue #9
Before this fix, the bug would only pop up for addresses that were
dividable by 4. Otherwise, the AMBA AHB 3 Lite widget would return an
error response because of an illegal HSIZE/HADDR combination.

Closes #4: Add support for hierarchical addrmaps
Every time an addrmap is detected within another addrmap, a new context
will be opened and a separate RTL file will be created.

All addrmaps will have the same bus-wdiget, but it might be possible
that different addrmaps have different maximum regwidths. For that
reason, it was necessary to change the non-generic srd2sv_if_pkg to a
parametrizable interface.

Almost all changes to the templates in this commit are due to name
changes from 'b2r' and 'r2b' to 'widget_if'.

Fix simple_rw_reg.rdl so that the test passes
The register was defined as a 64-bit register but the test was written
under the assumption it's a 32-bit register. Furthermore, the hardware
write-enable flag had to be set since all values would otherwise be
overwritten immediately.

Extend test_simple_rw_reg with 3 more tests
The following tests are now included:

    - Check access to registers over AHB bus
    - Check access to register over HW interface
    - Check access to register over HW interface if hw_wr-input
      is disabled.
    - Check if the slave responds with a correct error sequence if
      an illegal address is accessed.

Finish initial version of interrupt suport, closes #1
The software is now able to create most interrupt combinations of
Section 9.9 of the SystemRDL 2.0 LRM. It supports
stickybit/non-stickybit interrupts, it support posedge, negedge,
bothedge, and level interrupts, and it is able to generate all
surrounding logic.

This commit also fixes a reset-bug that caused registers that were reset
to 0 to be not reset (because 'if not reset_value' will return True if
the 'reset_value' is 0).

Add support for external registers
Every single field and every single alias (!) has its own
interface to the surrounding hardware. This is required
to give users the maximum amount of freedom when defining
certain properties in RDL.
