bd5fdb3b82 PR_INTERPHUDRANDOM
Fixes several things to do with the boss healthbar.
- Makes its randomised jitter work with interp/pause
- Constantly calling the external PRNG tanks performance, at least on Windows, so this solves that too

Done as a special non-netsynced random class so the author of this commit wouldn't have to create a third suite of duplicated Random functions.

845fe12b52 Conversion to using gamedata_t
A small piece of (STJr/SRB2!1756).
Due to how RR currently handles time attack records and how it WILL handle unlocks, it's not currently feasible to split everything such that you can have two independent gamedata_t... but what's done so far is certainly more sane and less dependent on global variables
Other minor refactors:
- M_UpdateUnlockablesAndExtraEmblems and M_SilentUpdateUnlockablesAndEmblems are now one function with a boolean for loudness
- Unlock prints are currently living in the console, since the cecho stuff was a little broken

492c068cdd Try some things to reduce rng biases
- Don't clamp all RNG calls to [0, FRACUNIT-1]. Only does this for P_RandomFixed now.
- Use rejection sampling for any clamped RNG calls, to remove modulo bias.
- Because of this, P_RandomRange ranges >= FRACUNIT are no longer undefined behavior.
- Added P_Random/M_Random to grab RNG output directly.
- Shuffle M_Random's RNG as well, since OS rand can be [0,INT32_MAX] instead of [0,UINT32_MAX].

3e4edc534d Remove strange RNG sync hack
Previously it was using P_SetRandSeed, which sets both initial and current seed to the same thing, since it's meant for level load init. It first set all RNG seeds to the current seed, and then it set all of the seeds to their initial value. The comment about this just says its "stupid and hacky", and I have no idea how it even worked before.

Now we send over both init seed and current seed independently and set them both. Hopefully this will fix the desyncs.

fbce35d27e cast P_Random(Key/Range) PRNG calls to INT64 to preserve old behavior
(it's still technically "undefined" behavior anyway)

ac03ce39c8 *_Random is now *_RandomByte.
P_RandomChance is now a macro for something that should happen a
certain percentage of time.

P_SignedRandom was moved to a macro. Nobody cared.

ce2c2de58a P_Random now using a variant of xorshift
This actually passes most diehard tests, as opposed to the old RNG.
It's also similarly fast.

Internally the PRNG generates a fixed point number from [0,1) now,
which makes P_RandomKey and P_RandomRange much easier to
calculate. P_Random is just a simple shift, as well.

Also, the lack of floating point math in P_RandomKey and
P_RandomRange now is probably for the best.
