Fold in Windows VPI routing for vpip_format_pretty, fix queue method
argument elaboration via elaborate_rval_expr, reject class tasks used as
expressions cleanly, and update br1005 now that class queues compile.
Review follow-up: move vpip_format_pretty to vpip_format.cc with
diagnostic return strings, restore NetNet-based queue method elaboration
with a separate property path, drop spurious /devel/ from .gitignore,
and bump copyright years on touched files.
Formatting pass per inline review: brace style for multi-line if bodies,
||/&& at end-of-line continuations, switch/case indentation, single-line
if returns, NetNet-based sys_task_method_ again, and aligned extern decls.
These were implemented as returning nothing (void), and passing an
invalid operation value would trigger an assertion failure. The IEEE
standards define them as returning 1 on success and 0 on failure.
vpi_sim_control() is the name used in Verilog-AMS. Strictly speaking
it should return a bool, but to avoid polluting the namespace by
including stdbool.h, we return a PLI_INT32. As C is a weakly typed
language, this should make no practical difference.
__CYGWIN32__ is not defined when building with the 64-bit Cygwin
toolchain. According to the Cygwin FAQ, __CYGWIN__ has been defined
since 1998, so this should still work for users on 32-bit systems.
The old scheme of linking the VPI modules with the vvp exports meant they
did not work when loaded by the compiler. Instead, let each client create
a jump table for the VPI routines and pass that to each VPI module as it
is loaded.
