Fix alias bugs introduced when adding external registers
Furthermore, some compilation bugs were added when optimizing away swacc
and swmod wires when not required.

Fix addrmap & memory/regfile/register/field-naming collision
For almost all variables, the addrmap is stripped of the name. However,
when a memory/regfile/register/field had the same name as the addrmap,
a part of that name would also be stripped.

Fix bug with dynamic saturate values and fix Lint warnings
Two categories Lint warnings occured:
    - Width mismatches, since integers are 32-bit wide according to the
      SV LRM.
    - Constant saturate values, because values could get larger than
      32-bit and smaller than 0.

Gather bit-ranges of byte-enable signal in error-wire
Previously, the error wire would be assigned like this:

    assign example_reg_err_mux_in = !((widget_if.r_vld && (widget_if.byte_en[0] || widget_if.byte_en[1] || widget_if.byte_en[2] || widget_if.byte_en[3])) || (widget_if.w_vld && (widget_if.byte_en[0] || widget_if.byte_en[1] || widget_if.byte_en[2] || widget_if.byte_en[3])));

Now, this same line is simplified to:
    assign example_reg_err_mux_in = !((widget_if.r_vld && (|widget_if.byte_en[3:0])) || (widget_if.w_vld && (|widget_if.byte_en[3:0])));

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 #8: Certain fields shall be implemented as wires or constants
The software now detects whether a field shall be implemented with
flops, with wires, or as a constant. Everything should now follow Table
12 and Section 9.5.1 of the SystemRDL 2.0 LRM.

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'.

Add hierarchical interrupts under examples
The SystemRDL that was added comes from Section 17.2 "Understanding
hierarchical interrupts in SystemRDL" of the SystemRDL 2.0 LRM. The
present code succesfully compiles.

Resolve UnboundLocalError bug when SignalNodes are instantiated
This happened in AddrMap and RegFile because a the width of a new
variable 'new_child' is performed. However, SignalNodes will not create
such a child.

Add option to add no bus-widget
If this option is defined, there will be a direct interface to the b2r
and r2b interface. The structs will be flattened out to wires for legacy
reasons.

This closes #3.

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.

Move several methods to common Components ancestor
For example, most methods relating to dimensions or genvars were moved
to the Components class.

Furthermore, some more care was taken of _ or __ prefixes for methods:

    - No method-prefix: Public variable that is will be called by
                        non-related functions and methods.
    - _  method-prefix: Method will be called by class or class that
                        inerhits class
    - __ method-prefix: Method will be called by class itself only
