Rework symbol_search function.
...
There are too many ad hoc handlers of symbol_search partial results.
Rewrite symbol_search to clean up things like partial results and
member/method detections. Use this reworked symbol_search function
to rewrite expression elaborate for the PECallFunction expressions.

Add support for string parameters
...
Parameters can have string type and do the usual string stuff,
and also implement some of the string methods on string parameters
so that they evaluate down to constants.

Rework parsing of parameter types
...
Use the common data_type_or_implicit rules to support type
definitions for parameters. This eliminates a bunch of special
rules in parse.y, and opens the door for parameters having
more complex types.

Fix expression type for packed struct member access (GitHub issue #386 )

A NetESelect is used for accessing packed struct members and also for
accessing dynamic array elements. In these cases the expr_type() and
enumeration() methods should reflect the member/element type.

Handle case that strings are arguments of functions/tasks.
...
When strings are arguments to functions/tasks, that doesn't suddenly
make them implicitly scalar. Strings are vectors and should be treated
that was, even if they are IMPLICIT_REG.
