Fix (shadings) : Remove colors from C stack.
DETAILS :
This is the 3nd step of fixing the bug 688955
"64K stack overflows with shadings".
This change is algorithmically equivalent.
1. New functions reserve_colors_inline, reserve_colors work with
the color stack in heap.
2. Currently the color stack pointer is saved at each
recursion level for simplifying the debugging.
We intend t move it later to the shading fill state structure.
Currently it is passed via most function calls as a new argument.
3. In automatic data the colors change type
from a structure to pointer.
4. Since we want to keep colors be constant while
the heavy decompositioin recursion, we made
the local color pointers point to const data.
Therefore a new argument is added to some functions,
which construct colors and therefore need
a non-conmst access. Thise changes are commented with
"providing a non-const access".
5. Minor change : cs_is_linear changes the 1st argument type to 'const'
(gscspace.c, gxcspace.h).
EXPECTED DIFFERENCES :
None.
