[PATCH] IPC: add PATH_MAX-less fallback definition for MAX_PATH

Define MAX_PATH also when PATH_MAX is not defined (e.g on GNU/Hurd).
MAX_PATH is Windows constant, and it is used in this file only in a
code path for Windows; because of this, the static fallback define
should be good enough.

[PATCH] Add clamping to QColorTransferGenericFunction

This ensures that the inputs are within range for the use of these
function.

Depending on the values passed, they can trigger FE_INVALID errors
and thus NaN as return values.

This can happen for example when feeding an invalid ICC profile to
QColorSpace::fromIccProfile.

[PATCH] QColorTransferGeneric: fix the BT.2100 PQ EOTF

The PQ EOTF formula for BT.2100 [1][2] was incorrect. Fix it; while at
it, rename the variables to match the symbols used in the original
formula.

The inverse EOTF was correct, but also rename the variables there (for
the same reason).
