Make sys_signame upper case.

This matches the constants from <signal.h> with 'SIG' removed, which POSIX
requires kill and trap to accept and 'kill -l' to write.

'kill -l', 'trap', 'trap -l' output is now upper case.

In Turkish locales, signal names with an upper case 'I' are now accepted,
while signal names with a lower case 'i' are no longer accepted, and the
output of 'killall -l' now contains proper capital 'I' without dot instead
of a dotted capital 'I'.

Two arrays were born from the same seeds, both grew into complementary sets
of pointers to strings. These two arrays were fixed to the same size, but one
had an implicit zeroed trailer element, which was unused because the size was
used up by the ones before said zeroed trailer element. So the unused limb was
chopped off the over-sized-but-not-over-sized array, and everyone lived happily
ever after.

Fix the style of the SCM ID's.
I believe have made all of libc .c's as consistent as possible.

Add a strsignal(3) (like strerror(3)) for libc compatability with other
systems. NetBSD, Linux, SVR4 etc all have it.
