Fix: Ensure 31-bit shifts are unsigned. (#10128)

Shifting a signed 32-bit integer by 31 bits is undefined behaviour.
A few more than necessary are switched to unsigned for consistentency.

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.

Fix e66cec8f86: Permit loading of industry production callback with invalid cargo type.

It is only an error if the invalid result is actually used. This will be silently ignored at the moment.
It is still an error if a duplicate cargo type is returned.

(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 r16404) -Fix [FS#2911] (r16378): the number of spritegroups got halved when the new pool was added, which mean there weren't enough spritegroups when you have more than about a dozen ECS vectors.
-Change: increase the spritegroup pool's maximum size to something more than the number of real sprites that OpenTTD can handle; for example ECS has about 30 spritegroups per real sprite. With the 'old' limit that would mean 'only' about 4000 real sprites worth of spritegroups could be loaded.

(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 r11797) -Fix: Add protection against not already created industry while doing industry callback.
Some variables used were linked to invalid industry.
