[PATCH] new valid_signal() function
This patch adds a new function valid_signal() that tests if its argument is a valid signal number. The reasons for adding this new function are: - some code currently testing _NSIG directly has off-by-one errors. Using this function instead avoids such errors. - some code currently tests unsigned signal numbers for <0 which is pointless and generates warnings when building with gcc -W. Using this function instead avoids such warnings. I considered various places to add this function but eventually settled on include/linux/signal.h as the most logical place for it. If there's some reason this is a bad choice then please let me know (hints as to a better location are then welcome of course).
