6f441292d0 CModule construction optimization
Moved construction logic to separate method, and call that from constructor instead. When willing to change the entire context on the same object, you can now just call 'InitFromXXXX()'. Previously, a whole new object would be generated and copied into ours, and then deleted again.

b4cd72034e CModule: light cleanup
Remove the option to disable dynamic init, it was broken anyways as the string was getting constructed, and therefore, dynamic memory could be allocated if string exceeds a certain size where it has to be moved from stack to heap. The only functions we were interested in, while not allocating anything have been made static instead in the last refactor round.

b76f4aa3bd CModule class improvements
*Use unordered_map to get mpdule sections instead, as this is more performant than comparing strings.
* Removed 'm_SectionName' field from ModuleSections_t, as the unordered map now keeps track of them.
* Removed all extraneous module section copies.
* Renamed 'GetImportedFunction' to 'GetImportedSymbol'.
* Renamed 'GetExportedFunction' to 'GetExportedSymbol'.
*Made a static version of 'GetImportedSymbol' and 'GetExportedSymbol', so it could be used on raw module base addresses.
*Created inlines for getting the DOS and NT headers.
*Improved formatting so the code could be read more easily on a vertical monitor.

975c40876a CModule and CMemory class improvements
This commit significantly reduces output code size, and a noticeable increase in performance. Changes are:
- Removed all extraneous std::string and std::vector copy constructions; use raw pointers instead to boost performance.
- Marked simple getters in CModule inline.
- Marked several functions in CModule const.
- Slightly reordered CModule class.
- 'CMemory::CheckOpCodes' and 'CMemory::Patch' now take a const reference.

359820615f Move low level code to tier0/tier1
Moved to tier0/tier1 so it could be compiled into a static library in the future.
