Looks like lots of water got in, doesn't it?

As an aside, one of the things that really impressed me about this old GM iron was the brakes. Mine were neglected when I got it. Leak in the rear line, crud (like dirt and stuff) in the master cylinder. The fluid was cloudy (though thankfully not jelly like yours). All I did was replace the rear line and flush the system several times with new DOT4 until it ran clear. By flush I just mean open the bleeder on each corner and stomp the pedal a lot. No bad master cylinder, no bad brake pistons, no leaks. Just a solid pedal and great braking. I've been through about 1.5 sets of front pads since then it's all great. Not sure the newer stuff would take that kind of abuse!

P.S. Oh yeah, I've got a great one-man-bleed technique: Get yourself a long hose for the bleed screw and a catch jar. Plug the end of the hose with a screw. Slit the side of the hose for a few inches near the end with the screw. Now you have a one way valve for cheap. When you stomp, the fluid bursts out. When any suction occurs the slit just sucks closed. Nice!

P.P.S. I would take the same approach as a first step. First I would scoop all the crud you can out of the master cylinder reservoir. Then I would fill with nice fresh fluid. Then I would blow about five or six bottles of brake fluid through the system by visiting each corner in turn and flushing until you see good fluid. Then I would flush some more. Don't forget to keep topping up so you don't get air in. Good luck!

Here's another thought: That still looks like water to me. Is the lid of your master cylinder sealing? Is the rubber gone or something?
