mesa: Returns a GL_INVALID_VALUE error on several APIs when buffer size is negative

Section 2.3.1 (Errors) of the OpenGL 4.5 spec says:

    "If a negative number is provided where an argument of type sizei or
    sizeiptr is specified, an INVALID_VALUE error is generated.

This patch adds checks for negative buffer size values passed to different APIs.
It also moves up the check on other APIs that already had it, making it the first

While there may be other APIs throughtout the code lacking this check (or at least
not at the beginning of the function), this patch focuses on the cases that break

glsl: Improve precision of mod(x,y)

Currently, Mesa uses the lowering pass MOD_TO_FRACT to implement
mod(x,y) as y * fract(x/y). This implementation has a down side though:
it introduces precision errors due to the fract() operation. Even worse,
since the result of fract() is multiplied by y, the larger y gets the
larger the precision error we produce, so for large enough numbers the
precision loss is significant. Some examples on i965:

Operation                           Precision error
-----------------------------------------------------
mod(-1.951171875, 1.9980468750)      0.0000000447
mod(121.57, 13.29)                   0.0000023842
mod(3769.12, 321.99)                 0.0000762939

mod(-987654.125, 123456.984375)      0.0160663128
mod( 987654.125, 123456.984375)      0.0312500000

This patch replaces the current lowering pass with a different one
(MOD_TO_FLOOR) that follows the recommended implementation in the GLSL
man pages:

mod(x,y) = x - y * floor(x/y)

This implementation eliminates the precision errors at the expense of
an additional add instruction on some systems. On systems that can do
negate with multiply-add in a single operation this new implementation
would come at no additional cost.

v2 (Ian Romanick)
