attach injection on Linux

this was PR 204490

focusing on Linux as Windows has issues that are best solved with a kernel driver, unless we think we can rely on backward decoding heuristics or don't mind losing control for a while

we do have some issues on Linux:

• ability to suspend threads before we have control of them: we will probably rely on ptrace (xref issue #37 )
• determining the state of sharing of CLONE_* among threads: should probably use a modify-and-observe approach
