inferior_thread_state contains state about the program itself like its
registers and any signal it received when it last stopped.
This state must be restored regardless of how the inferior function call
ends (either successfully, or after it hits a breakpoint or signal)
if the program is to properly continue where it left off.

the handling of SIGSTOP for a ptraced process has changed. Earlier
versions of the kernel would ignore these SIGSTOPs, while now
SIGSTOP is treated like any other signal, i.e. it is not muffled.
If the gdb user does a 'continue' after the 'attach', gdb passes
the global variable stop_signal (which stores the signal from the
attach, SIGSTOP) to the ptrace(PTRACE_CONT,...) call. This is
problematic, because the kernel doesn't ignore such SIGSTOP
now. I.e. it is reported back to gdb, which in turn presents it
back to the user.
To avoid the problem, we use STOP_QUIETLY_NO_SIGSTOP, which allows
gdb to clear the value of stop_signal after the attach, so that it
is not passed back down to the kernel. */

/* If STARTUP_WITH_SHELL is set, GDB's "run"

This is in order for argument-expansion to occur. E.g.,
(gdb) run *
The "*" gets expanded by the shell into a list of files.
While this is a nice feature, it turns out to interact badly
with some of the catch-fork/catch-exec features we have added.
In particular, if the shell does any fork/exec's before
the exec of the target program, that can confuse GDB.
To disable this feature, set STARTUP_WITH_SHELL to 0.
To enable this feature, set STARTUP_WITH_SHELL to 1.
The catch-exec traps expected during start-up will
be 1 if target is not started up with a shell, 2 if it is.
