It implements the "startup-with-shell" feature on gdbserver. This means that it will be possible to start inferiors using the shell (instead of calling execv*), which brings many advantages. First of all, it will be possible to use I/O redirection, variable substitution and globbing expansion on gdbserver just like we do today on GDB. This is great because, among other things, it brings gdbserver on a pair with GDB when considering the Feature Parity project. Secondly, a great deal of code had to be shared between GDB and gdbserver, especially the fork_inferior function, which means that now both programs are using virtually the same code to start inferiors. I've also had to touch on other areas, like terminal.h, inflow.c and gdbthread.h, and even though only the APIs were shared (i.e., gdbserver's version of a gdbthread.h function may differ from GDB's version), this is also beneficial in the long run when we start to unify the code more deeply. But I'm "raining in the wet" here; all this has been explained in better terms before. I did my best to split the patches, but unfortunately the fork_inferior patch is big and I couldn't see a better way to do that. But it shouldn't be very hard to review them, because most of it is just "code movement". Thank you, and happy holidays!
