general uniforms support

9

Hi This feature is unfinished but I think it should help. Usage: ``` ./ffmpeg -i media/0.mp4 -i media/1.mp4 -filter_complex "gltransition=duration=4:offset=1.5:source=WaterDrop.glsl:uniforms='amplitude=10.0&speed=15.5'" -y out.mp4 ``` Limits: only `int` and `float` are supported

使用一个定长数组作为buf， 减少因为数组resize导致的额外realloc开销。 在个人电脑上 utf8的性能提高5%左右，非utf8有微小提升。 测试机器： MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports) 8 GB 2133 MHz LPDDR3 256G ssd
