to reduce the call indirections with u_resource_vtbl.
The worst call tree you could get was:
- u_transfer_inline_write_vtbl
- u_default_transfer_inline_write
- u_transfer_map_vtbl
- driver_transfer_map
- u_transfer_unmap_vtbl
- driver_transfer_unmap
That's 6 indirect calls. Some drivers only had 5. The goal is to have
1 indirect call for drivers that care. The resource type can be determined
statically at most call sites.
The new interface is:
pipe_context::buffer_subdata(ctx, resource, usage, offset, size, data)
pipe_context::texture_subdata(ctx, resource, level, usage, box, data,
stride, layer_stride)
v2: fix whitespace, correct ilo's behavior
