Fix presence of unsigned in a parameter signature resetting the type

name being constructed. In the common case of using an unsigned
parameter this was typically harmless.

When unsigned was used as part of a template type parameter this would
overwrite the type info already built up, so:

   array<unsigned int>

would become:

   unsigned int>

The parameter types were being used only to generate the hash to pair
with whatever clscan generates. The side effect of which being, any
function that suffered from this problem would not have its call address
patched up.

Function parameter serialisation constructs/destructors template params.

replicate_transient attribute.

Export transient flag.

(these should all really be custom flags to prevent changing tools)

Fix stack overflow parsing very large JSON arrays.

Versioned binary support for skipping transient classes.

Specify which transient flags to filter for JSON serialisation.

Fix the chicken-and-egg problem where you use type hashes generated from

types in the same library:

1) clscan parses your C++ file.
2) Your C++ file includes clcppcodegen.h.
3) OOPS! That file is generated by step 5 and doesn't exist yet.
4) clmerge parses the output from clscan.
5) clmerge generates clcppcodegen.h.

Make clcpp::GetTypeNameHash constexpr so that you can use them as

switch case values and parameterise in other ways.

clcpp::GetTypeNameHash returns the hash as a constant rather than

looking it up in the table. Two benefits:
* Faster runtime.
* Can be used immediately at startup without calling clcppInitGetType.
