* Switched hashtables.h over to std::undordered_map from boost version.
* Added new macros DECL_VEC_FOR_SWIG() and DECL_MAP_FOR_SWIG() in macros.h.
These along with future DECL_HASH_FOR_SWIG() unify the declaration to swig
and C++ so that the resultant type name is common in both languages, and
the types AGREE.
* Fixed swigging of NETINFO_ITEM and NETINFO_LIST via magic.
* Newly exposed (python wrapped) are: D_PADS, TRACKS (was TRACK_PTRS),
NETNAME_MAP, NETCODE_MAP, wxString (without constructor purposely, read
comment in wx.i), MARKERS, ZONE_CONTAINERS, NETCLASSPTR, KICAD_T types.
* std::vector<SOMETHING*> tends to end up named SOMETHINGS in C++ and python.
Having the name consistent between like types is helpful, and between
languages. std::map<> ends up as SOMETHING_MAP.
* NETINFO_LIST::m_netNames and NETINFO_LIST::m_netCodes are now std::map
instead of hashtables, because swig does not yet support std::unordered_map.
* You can now get to any netclass or net info. NETNAMES_MAP and NETCODES_MAP
are traversable basically the same as a python dictionary using a python
string (not wsString) as the key! The wxString typemap converts python
string to wxString before the lookup happens. Iteration also works.
To use multiple working threads. This entailed adding KiCad typedefs:
*) Add typedefs for MUTEX and MUTLOCK which mask the actual choices for the project.
*) Add FOOTPRINT_LIST::DisplayErrors( wxWindow* ) which is a single strategy for
showing aggregated load errors. Although what's there is only scaffolding
and needs a volunteer who knows HTML pretty well.
*) Ensure all callers of ReadFootprintFiles() use the new DisplayErrors() function.
*) Push utf8.cpp and utf8.h into common library for open use.
