On Android, fcntl is always implemented by fcntl64(2). This means that an LP32 binary can `fcntl(F_SETLK, struct flock)` (because fcntl64(2) passes through to the 32-bit fcntl(2) to handle F_SETLK), and it can also `fcntl(F_SETLK64, struct flock64)`. What it can't do before this patch is set _FILE_OFFSET_BITS=64 and then `fcntl(F_SETLK, struct flock)` where that `struct flock` is actually implicitly `struct flock64`. Move the kernel uapi structs out of the way, define them ourselves based on __LP64__ and _FILE_OFFSET_BITS, and fix up the relevant F_ constants. (Also add a .clang-format to turn off clang-format in libc/include/.) Bug: N/A Test: treehugger (and strace!) Change-Id: Iccd6c83d9133e1efcf93a7b49a6ae0f1bbd3d58b
