Extend the non-blocking event control assignment tests to check that a 0 or
negative repeat value is handled correctly. In this case the assignment
should be executed like a regular non-blocking assignment and the event
control should be ignored.

Check that continuous assignments to unpacked net arrays preserve delay and
drive strength on the generated element drivers.

Check that SystemVerilog net declarations can mix entries with and
without initialization.
Check that in SystemVerilog it is possible to do assignments within net array
declarations.

Check that continuous assignment of an assignment pattern to a single element
unpacked array is accepted. Check that assigning a scalar expression to the
whole unpacked array is rejected for both procedural and continuous
assignments.
Check that a selected element of a single element static unpacked array can be
used in a continuous l-value concatenation.

Check that enum, struct, union and class restricted type parameters are
accepted. Check that mismatched default values and overrides are rejected.

Check that soft packed unions can have members with different widths.
Check that the `soft` qualifier implies `packed` and that nested soft
packed unions use the same representation recursively.
Also check that member bits are right-justified and that assignments to
narrower members leave the MSBs beyond the member bits unchanged. Check
that soft packed unions reject default member values.

Check that each valid `begin_keywords` selector is accepted. Only check
that the selector itself is accepted, in these tests there is no check if
the correct keywords are actually accepted or rejected since that would get
pretty exhaustive.

Add flags to enable IEEE1800-2017 and IEEE1800-2023 languages generations
and also support them in the `begin_keywords macro. Since neither defines
new keywords they'll use the same keyword mask as 2012.
Update the driver, compiler, documentation and regression test harness so
-g2017 and -g2023 are recognized as language generation flags.
There are no specific features from these versions added yet, this is just
the necessary infrastructure to allow gating new features from those
generations when they are added later.

A few JSON regression test entries reference the wrong source or gold
files. There are also two regress-vvp list entries that reference each
other's JSON file.
Use the matching source and gold files for those entries.

The sv_mixed_assign2 JSON entry accidentally references
sv_mixed_assign1.v. Point it at sv_mixed_assign2.v instead.

Check that class objects, dynamic arrays, queues, strings and static
unpacked arrays can not be used as l-value concatenation operands. Check
procedural and continuous assignment concatenations, including single
operand concatenations.

Check that the compiler reports an error for `posedge`, `negedge` and `edge`
event controls on named events. Edge controls can not be used with named
events.
There is already an existing test that checks both `posedge` and `negedge`.
Split it into separate tests so that each invalid event control is checked
independently.

Replace .github/test.sh with a unified set of targets installed
via `make check-*` in ivtest/, thereby removing CI-specific test
coordination. This avoids duplication in the regression logic and
ensures consistent execution between local and CI environments.
PLI1-dependent tests are now correctly controlled via
`configure --enable-libveriuser`.
Currently, the regression suite still depends on an iverilog package,
which must be installed manually at the location specified with
`configure --prefix=*`. Afterward, the complete regression suite
(VVP, VPI, and Python tests) can be run via `make check-installed`
and individual checks can be run with `check-installed-vpi`,
`check-installed-vvp` and `check-installed-vvp-py`.
