Codechange: automatic adding of _t to (u)int types, and WChar to char32_t

Codechange: Deduplicate ResolveReal() for resolvers that don't use real sprite groups.

This may change behaviour when multiple loading/loaded stages are provided, as the various copies checked in different orders, however only one result is expected in these cases anyway.

Feature: NewGRF callback profiling (#7868)

Adds a console command newgrf_profile to collect some profiling data about NewGRF action 2 callbacks and produce a CSV file.

(svn r27989) -Fix (r27985): VA2 optimisation failed in various special cases:
- nvar=0 is meant to return the calculated result.
- Missing references resolve to NULL and got identified with the default result.
- Missing 'break' broke overlapping cases.
- Splitting into non-overlapping cases could result in more than 256 cases.

(svn r27928) -Fix: [NewGRF] While executing random triggers, var 5F should include the new triggers.
-Fix: [NewGRF] Reset used random triggers only after all A123 chains have been resolved, so that all RA2 in all chains can test the shard triggers. This also includes multiple RA2 in the same A123 chain.
-Fix: [NewGRF] Industry random triggers are stored per tile, even when randomising the shared random bits of the parent industry.

(svn r17672) -Revert (r8081): 'last_value' and 'reseed' are shared between procedure and main chain.
-Fix (r8075): 'scope' and 'count' are not.

(svn r12352) -Fix: Some callback-results were treated as 8 bit, when they were 15 bit, and vice versa.
Var 0x7E procedure-results are always 15 bit.
Callbacks 0x2A, 0x2C, 0x36 (sometimes), 0x39 and 0x145 are 15 bit.
Non-varaction2-calculated callback-results are also affected by the 8bit masking.

(svn r12124) -Codechange: Move newgrf-variables that are common to VarAction2 and Action7/9/D to their own function.
-Fix: Add some variables that were missing in one or both cases.

(svn r11412) -Fix (r11403): animation was not turned on properly.
-Fix (r11410): wrong assumption about random reseeds made the whole thing reseed way too often, making the animation look very ugly.
