proc/native,proc/gdbserial: let target access terminal Change the linux verison of proc/native and proc/gdbserial (with debugserver) so that they let the target process use the terminal when delve is launched in headless mode. Windows already worked, proc/gdbserial (with rr) already worked. I couldn't find a way to make proc/gdbserial (with lldb-server) work. No tests are added because I can't think of a way to test for foregroundness of a process. Fixes #65 2018-04-16 10:01:08 +00:00			`import (`
proc/native,proc/gdbserial: ignore SIGTTIN, SIGTTOU when fg'ing target If we send a process to foreground while the headless instance may get a SIGTTOU/SIGTTIN, if not ignored this signal will stop the headless. It's not clear why this only happens the second time we do this but that's how it is. Also removes the direct syscall to TIOCSPGRP and lets the go runtime do it instead.
