Several source and netlist objects inherit `LineInfo` while separately
storing the lexical position associated with the same source location. This
requires callers to copy the file, line, and lexical position independently.
Add the lexical position to `LineInfo`. Have `set_line()` initialize it when
it is unset, so new objects inherit the complete source location while later
diagnostic location updates preserve their established declaration order.
Initialize the field to `UINT_MAX` so zero remains available as a valid
scanner position and missing initialization is distinguishable. Have
`FILE_NAME()` preserve a more precise identifier position.
Remove constructor parameters that duplicate the position supplied through
`FILE_NAME()`. Use the shared field for identifiers, wires, events, event
triggers, nets, and elaborated events. Assign static class property nets
their declaration location since they previously relied on the standalone
`NetNet` position defaulting to zero.

The LineInfo class defines a copy-constructor, but relies on the default
copy-assignment operator.
In newer versions of C++ this deprecated and modern compilers generate a
warning about this. A class must either use the default copy-constructor
and default copy-assignment operator or provide a user defined version of
both.
Since the current user-defined copy-constructor for LineInfo does the same
as the default copy-constructor, remove the custom one and rely on the
default constructor.

Include the compiler infrastructure to vhdlpp for collecting the
file and line information and attaching it to entities and ports.
Make the parser store the file name during parse.
Create a libmisc library where I can put source files that are
used by multiple programs within the source tree.
