KernelUtils: early init kernel version ... (unfortunately need to keep kernelVersion() around for some uses outside of p/m/C) The goal of this is to make isAtLeastKernelVersion() checks cheaper. Currently they all have to check that we've already parsed uname... We use that all over the place, even at runtime in BpfMap.h.

bpf: switch progs from using 'pin_prefix' to 'pin_location' ... Note: I discovered that C considers: char s[4] = "abcd"; a valid initialization without a terminating NULL, resulting in an invalid string. (Specifically pinned programs had a '\1' as their last char due to little endian encoding of the next field in the array of prog def structs) The simplest workaround appears to be to explicitly add a "\0" That results in a string/array that ends with 2 NULLs, and the compiler will at most *strip* the final one. ie. char s[4] = "abcd\0"; fails to compile. Obviously: char s[100] = "abcd\0"; also does the right thing, since it 0-pads with or without the extra null.
