This change adds `ProcessVmRead` and `ProcessVmWrite` wrappers around the syscalls `process_vm_readv` and `process_vm_writev`, available since Linux 3.2. These follow the same permission model as `ptrace`, but they don't actually require being attached, which means they can be called directly from any thread in the debugger. They also use `iovec` to write entire blocks at once, rather than having to peek/poke each `uintptr`. These wrappers are used in `Thread.ReadMemory` and `WriteMemory`, still falling back to `ptrace` if that fails for any reason. Notably, `process_vm_writev` respects memory protection, so it can't modify read-only memory like `ptrace`. This frequently occurs when writing breakpoints in read-only `.text`, so to avoid a lot of wasted `EFAULT` calls, we only try `process_vm_writev` for larger writes. |

About Delve
Delve is a debugger for the Go programming language. The goal of the project is to provide a simple, full featured debugging tool for Go. Delve should be easy to invoke and easy to use. Chances are if you're using a debugger, things aren't going your way. With that in mind, Delve should stay out of your way as much as possible.
