Akash 984fcfda2e Counters: Update videomode enum with proper prefix
Thanks to @colepcsx2 (https://github.com/PCSX2/pcsx2/pull/1896#commitcomment-21858717) for pointing it out!

I also updated the prefix in the inferior video mode detection of GSdx, I'm not even sure why we need the videomode info on the plugin side, might be useful someday.

Akash 38c2de3ae3 GSdx-PCRTC: Minor modification to NTSC saturation
Allow the output circuit saturation to take place at cases where one of the output circuit is enabled with frame mode rendering, I'm not sure it would be safe to allow saturations when both of the output circuits are enabled with frame mode rendering. Unlike field mode rendering, frame mode doesn't use identical rectangles at same co-ordinates for output in two alternating fields and potentially they could use a much bigger output size when both of the output circuits are enabled and are separated without any intersection. So let's limit the saturation to only the cases where we detect a single output circuit for frame mode rendering.

Fixes a regression in Devil May Cry 3 and Sky Gunner.

willkuer a18d624bcb gsdx: Add an automatic CRC hack level
If a user switches renderer they also have to remember to change the CRC
hack level for the best user experience with the selected renderer.

This commit adds a new automatic CRC level that autoselects the
recommended CRC level for the selected renderer, so that a user doesn't
have to make the change manually.

Akash 500d2e076d GSdx-PCRTC: Apply saturation only for field mode
Previously, the NTSC saturation was also applied for double scan mode (Interlaced and Frame) where the developers send double the height to the DISP registers, saturation shouldn't be performed at such cases as the developers could send a value of 780 while the real size of the output would be 390 due to double scan mode. Doing the saturation later after identifying the real size also seems a bit counter-intuitive as we haven't discovered any cases where double scan games require the NTSC saturation hack. So let's just apply the saturation only for Interlaced (Field) Mode and omit the saturation step for other modes.

Akash 17b33afd64 GSdx-PCRTC: Move hacks away from GetDisplayRect()
Isolate all the hacks into a separate subroutine and properly document about them, should make it easier for people to understand the display rectangle setup code, the hacks were totally messing up the readability of the function earlier.

Akash a2cdcb4e4d GSdx-PCRTC: Improve output circuit selection
Previously, the auto output circuit selection of the GSdx wasn't good, it simply defaulted to the second output circuit even when the first output circuit is also enabled. The new algorithm for auto selecting returns the merged rectangle dimensions when both of the output circuits are enabled and if the condition for merge is not satisfied then it returns the bigger output circuit.

Akash 09c72375ab GSDX: Pass total height of framebuffer on GetOutput()
Some PSX games seem to store image data of the drawing results in an undeterminate area out of range from the current context buffer. At such cases, calculate the height of both the frame memory rectangles combined.

What happens on "Crash bash" -

* At first draw, scissoring is limited to SCAY0- 0 & SCAY1- 255
* At second draw, scissoring is limited to SCAY0- 255 & SCAY0-511

Previously, we limited the height to the value of one single output texture, so instead of that let's calculate the total height of both the two buffers combined to prevent such issues.

Akash b56ff3fce7 GSDX-TC: Pass merged output size for scaling
Passes the merged output circuit as the base size for texture cache scaling code. Helps fixing scaling issues where games use both of the output circuits for rendering.

Future Note: Alter the behavior of IsEnabled() check always preferring the second output circuit for some weird reason. I plan on changing it to a better auto-output circuit selection mechanism but that could probably be done some time in the future.

Akash 61a6fe9cd9 GSDX: Apply saturation only to interlaced video mode
JMMT uses a bigger display height on NTSC progressive scan mode, which is not really unusual hence adjust the saturation hack to only take effect on interlaced NTSC mode.

However, the whole double screen issue on FMV still exists. As a bit of information, this game has the second output disabled but seems to have some valid data inside of it, maybe the second output data is leaked into the first one? most likely a bug in the frambuffer data management rather than a CRTC issue (needs to be investigated)

Gregory Hainaut b34243fa7b gsdx state: TEX0 write behavior might depends on the context
Game: harley davidson
* write tex0 ctx0
* write tex0 ctx1
* draw  ctx 0

Previous GSdx behavior will load the clut every write of TEX0. In the
above case the draw will take the wrong clut.

To be honest, it could be a wrong emulation on the EE core emulation.
The hardware likely got a single clut (1KB cache is quite expensive)
So clut loading must be skipped if the context is wrong.

Next draw will use the ctx1 clut so I apply TEX0 when the context is switched

Please test harley davidson :)

v2: detect context switch from UpdateContext function
V3: always set m_env.CTXT[i].offset.tex, avoid crash (Thanks to FlatOutPS2 that spot the issue)
V4: move bad psm correction code (rebase put it in the wrong place)

Gregory Hainaut 029d74f855 gsdx: add an auto flush hack to implement a Read Write GS effect.
It impacts all renderers. It ought to fix issue in GTA radiosity,
Shadows in Jak series. (note shadows will suck in upscaling)

Implementation is really brutal. Expect a massive slow down, but at least we can test the effect
easily.

Normally perf impact will remain reasonable if the game doesn't use a Read-Write effect

Performances number are welcomes (my guess is really awful in HW mode, slow in SW mode).
You can enable it with "UserHacks_AutoFlush = 1"

Gregory Hainaut c9a1558c60 gsdx: save the blit buffer register when a transfer is started
Fix motocross mania missing texture. Close #1319

As far as I understand, transfer is initialized in DIR. But the real

by a new value.
