Before, they were assuming any joystick had at least 1 hat; this way, they now treat it similarly to buttons. If requesting the status of a button the joystick doesn't have, they return 0. If the joystick doesn't have a hat, querying a hat position will likewise now also return 0. This code will obviously need changed when we get around to proper (e.g. multiple) hat support.
This creates a factor that is used to multiply the timestamp. It will
overflow less, (once every 300 years or so) and not lose as much precision
as the previous implementation.
The performance is slightly improved, there are no more branches and one
floating point multiply.
Note: this relies on long double having a 64 bit mantissa. This is the
case on x86 Windows, Linux, and Mac OS. However, it is unconfirmed to
work on other architechtures.

The new design is centered around the Event Trace JSON format but it
should still be possible to adapt it for other profiling tools. The old
profiling system has been removed.
See also my comments on #762. The flag is almost entirely redundant, so this PR removes it in all instances where it's used in the ballistic primaries code. There are one or two places where removing it was not a no-op, so I adjusted the rest of the code accordingly (most notably in the parsing validation when it checks that primary weapon cargo has been assigned). I also added a few divide-by-zero checks and slightly tweaked the support ship rearm code. The use of the SIF_BALLISTIC_PRIMARIES flag in the ingame_join code was replaced with a dummy value to avoid bumping the multiplayer packet version number.
This disables all mouse grabbing which is useful for debugging when SDL gets interrupted without giving up
control of the mouse. That usually leads to problems since you can't
interact with the debugger window anymore.
* Adds VM_CENTERING to replace view_centering
* view_modify() now takes care of centering the view
* Reorganized view-related controls and logic to be cleaner
The new joystick API (commit f91c681ee1) didn't include calls to joy_ff_init() and joy_ff_shutdown(), disabling haptic support. Simply restoring these calls was enough to make it work on my system again.
If CurrentJoystickGUID was present but set to an empty string, the new code was comparing all joystick GUIDs against the empty string, and therefore concluding that no joystick was currently selected. This just treats an empty string as though CurrentJoystickGUID weren't set at all, allowing the index-based CurrentJoystick to take over.
Kobrar reported that joystick events were not properly assigned to the
right Joystick instances because the GUIDs of the joysticks was the same
(that's another problem since the code assumes that they actually are
Globally Unique like the name says).
The fix was to simply use the instance ID for checking if two sticks are
the same which seems to work more reliably.
* There's now registers for both 4 position and 8 position hats for both timestamps and downcounts
* There's conversion code to allow an 8-position hat to act like a 4-position hat, which is needed by the FSO codebase which only uses 4-pos hats
* There's also conversion code to allow a 4-pos hat to act like an 8-position hat to some degree.
This introduces a new mechanism for handling bit flags. Instead of using an int (or two, or three) to write bits into, this uses the std::bitset in a wrapper class that accepts an enum class as input. This means that certain classes of errors we've had a few of in the engine, where a coder used the wrong set of flags or checked them against the wrong variable (SF_STEALTH vs SIF_STEALTH, for example) can now be detected at a compiler level rather than not at all.
getHatPosition() returns a value from the HatPosition enum, so the conversion to a 0-based index is incorrect (and causes the hat switch to basically not work with continuous controls).
When the hat switch code was fixed to restrict joysticks to 32 buttons again, it forgot to invalidate buttons between numButtons() and 32. This could lead to some assertions being failed when the joystick got asked for the status of a nonexistent button.
* Fix (undocumented) issue with hat presses not registering.
* Use array instead of a vector for _hat::DownCount
* No, no die-nam-ick numbor of boot-ons to-day. Und no, ve only haff vone hat. Sad Heavy is Sad.
* Fixes an out-of-bounds error caused by incorrect indexing in Joystick::handleHatEvent.
Also fixes a bug where the hatGetDownTime would return a nonzero value if the hat was active but in a different position than the input parameter.
SDL_HAPTIC_SQUARE was removed immediately before the SDL 2.0.0 release and replaced with SDL_HAPTIC_LEFTRIGHT, due to running out of bits. SDL_HAPTIC_SQUARE is a periodic effect. SDL_HAPTIC_LEFTRIGHT is for controller rumble. Just because the latter replaced the former doesn't mean they're equivalent (and in fact they are completely different, which results in a malformed effect that won't work right, if at all). As a result, I've replaced the effect with SDL_HAPTIC_SINE, since a sine wave is the closest periodic effect to a square wave. This allows the effect to actually work, although not in exactly the same way as it would if it were actually a square wave (SDL 2.1 is supposed to contain SDL_HAPTIC_SQUARE again and presumably the effect can be changed back to a square wave whenever that happens).
