patchbomb: make it easy for the user to decline sending an intro message. - prompt(): respect interactive mode; clarify logic a bit - rename introneeded() to introwanted() and give it only one caller - add 'numbered' arg to makepatch() so it does not need to call introwanted() - factor makeintro() out of getpatchmsgs(), so it's easier to skip the intro message based on the user's behaviour Unexpected but perfectly reasonable side effect: in non-interactive mode, we don't show unanswerable "Cc" or "From" prompts anymore, so remove those from the test expectations.

building: build inotify for sys.platform='linux*' If Python interpreter was built under Linux 3.x kernel, it reports sys.platform to be 'linux3' (it is fixed for Python 3, but not for 2.x). This cancels building inotify extension, which was built only for 'linux2' platform. Improved test checks if sys.platform begins with 'linux', and together with test for kernel version to be greater than 2.6 it seems to cover all known cases.

patchbomb: simplify some contorted logic and odd variable names.
