POSIX allows any `int` value to be returned but specifies that only
the low 8 bits are available in some contexts:

For reasons that aren't entirely clear, WASI requires the value to be
in range [0;126), and this is enforced with an assertion at runtime
level in Wasmtime. This should probably be fixed in Wasmtime but until
it is done there doesn't seem to be any harm in returning `125` instead
of `-1`. This also removes any discrepancy due to truncation.
Define open_(o|i)fstream_and_log_error in log.h to:
- quote 'filename'
- add error cause to easier troubleshoot
- use existing consistent string style
- easily allows OS specific message
Introduce it when file are opened and add it where error message
was missing.

prjunnamed does not emit a net alias for toplevel ports. This works
fine for constraining IOs but breaks clock constraints. This commit
expands clock constraint application code to look up net aliases first,
ports second.
Two user-visible changes were made:
* `-DUSE_RUST` is replaced with `-DBUILD_RUST`, by analogy with
`-DBUILD_PYTHON`
* `-DCOVERAGE` was removed as it doesn't work with either modern GCC
or Clang
