Introduce option DDB_STRUCT. Kernels compiled with this option (except on
a few arches where toolchain limitations apply) will embed some symbolic information about the various structs used within the kernel, and have new ddb commands allowing struct display and some useful information gathering. Kernel rodata increase varies accross platforms from ~150KB to ~300KB. This option is not enabled by default.
