Per IEEE 1800-2017 6.5, variables can be written by one port, including
primitive gate outputs. The code incorrectly disallowed this with the
comment "Gates can never have variable output ports."
Changed elaborate_lnet/elaborate_bi_net calls for gate outputs to pass
true for var_allowed_in_sv, allowing variables as single-driver outputs.

The tgt-sizer target now skips IVL_SCT_PACKAGE scopes (the SystemVerilog
$unit compilation unit scope) instead of erroring. This allows sizer to
work with -g2012 and other SystemVerilog modes.

Modified grammar in parse.y to use identifier_name instead of IDENTIFIER
in function/task declaration rules and hierarchy_identifier rule. This
allows TYPE_IDENTIFIER tokens (which class names become after definition)
to be used as method names.
Changes:
- Function declaration rules (lines 1585, 1605, 1631)
- Task declaration rules (lines 2445, 2472, 2501)
- hierarchy_identifier member access (line 4471)

When $bits() is called with an undefined identifier, the compiler now
properly reports an error instead of silently returning 0.
The fix checks if the argument expression has type IVL_VT_NO_TYPE after
test_width() processing (indicating the identifier couldn't be resolved),
and triggers elaboration to produce a proper error message.

The vvp/ivl_dlfcn.h and cadpli/ivl_dlfcn.h files are essentially the
same, but have diverged a bit over the years. Merge them into a single
shared file at the top level. Use the static prefix for all inline
functins (currently only used in the cadpli version) as that will fix
issue #1301. We now require the compiler to support at least C99, so
can use "inline", not "__inline__".
