f5b1a5cd58 Fix make support for BSD ar (#2999) (#3256). [Julie Schwartz] 
While GNU 'ar' supports '@' to specify a file, BSD 'ar' does not.
The max line length can be handled by 'xargs' instead, which will know
to break up the command.  In case there are multiple calls, only build
the index (specified with '-s') once in a later call.

Reduce .rodata footprint of trace initialization (#3250) 
Trace initialization (tracep->decl* functions) used to explicitly pass
the complete hierarchical names of signals as string constants. This
contains a lot of redundancy (path prefixes), does not scale well with
large designs and resulted in .rodata sections (the string constants) in
ELF executables being extremely large.

This patch changes the API of trace initialization that allows pushing
and popping name prefixes as we walk the hierarchy tree, which are
prepended to declared signal names at run-time during trace
initialization. This in turn allows us to emit repeat path/name
components only once, effectively removing all duplicate path prefixes.
On SweRV EH1 this reduces the .rodata section in a --trace build by 94%.

Additionally, trace declarations are now emitted in lexical order by
hierarchical signal names, and the top level trace initialization
function respects --output-split-ctrace.

Fix re-evaluation of logic dependent on state set in DPI exports (#3091). 
Verilator should now correctly re-evaluate any logic that depends on
state set in a DPI exported function, including if the DPI export is
called outside eval, or if the DPI export is called from a DPI import.

Whenever the design contains a DPI exported function that sets a
non-local variable, we create a global __Vdpi_export_trigger flag, that
is set in the body of the DPI export, and make all variables set in any
DPI exported functions dependent on this flag (this ensures correct
ordering and change detection on state set in DPI exports when needed).
The DPI export trigger flag is cleared at the end of eval, which ensured
calls to DPI exports outside of eval are detected. Additionally the
ordering is modifies to assume that any call to a 'context' DPI import
might call DPI exports by adding an edge to the ordering graph from the
logic vertex containing the call to the DPI import to the DPI export
trigger variable vertex (note the standard does not allow calls to DPI
exports from DPI imports that were not imported with 'context', so we
do not enforce ordering on those).

4ab4c0c8ba Emit parameter values as 'static constexpr' instead of enum 
All parameters that are required in the output are now emitted as
'static constexpr, except for string or array of strings parameters,
which  are still emitted as 'static const' (required as std::string is
not a literal type, so cannot be constexpr).  This simplifies handling
of parameters and supports 'real' parameters.

ab4063f098 Emit implementations into separate files based on required headers. 
This patch partitions AstCFuncs under an AstNodeModule based on which
header files they require for their implementation, and emits them
into separate files based on the distinct dependency sets. This helps
with incremental recompilation of the output C++.
