The clang dlltool is not compatible with the binutils dlltool. However
both the clang and binutils linkers support reading the .def file and
creating the import library directly, so we no longer need to perform
the link in two stages.
We need to build libvvp with a suffix from the outset to ensure that
the vvp binary searches for the correct library file name once it is
installed.
Also Windows DLLs need to be stored in the same directory as the main
program, not in a separate lib directory.
Commit 95810b2f61 mistakenly added the suffix to the output file name
when linking the final vvp.exe binary. 'make check' and 'make install'
assume the suffix is only added when installing.
The tgt-vvp code generatpr outputs identifiers as quoted strings, and
because of this, escapes any " and \ characters (which may appear in
escaped indentifiers). We need to undo this when reading them into
vvp, so that the original name is seen by the VPI routines.
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.
Improve path search between nets, so that paths containing
concats as well as part selects can be found.

Logic type class properties use the wrong constructor resulting in a
default value of a vector with 0 width. Switch to the right constructor to
fix this.

The code doesn't currently handle the case of different bits within
the vector needing different delays (e.g. when the rise and fall
delays are different and some bits are rising as other bits are
falling) and aborts with an assertion failure. For now, output a
suitable "sorry" message and exit gracefully.
This adds a "-q" option on the vvp command line and a vvp_set_quiet_flag()
function in the VVP library API. Setting this flag will cause all output
to standard output via MCD bit 0 to be suppressed. It will not prevent the
output being sent to a log file if the vvp "-l" option has been used, and
it will not affect output to the STDOUT file descriptor.
