sleep: code shrink
Use less stack by using same "sigset_t set" object for new and saved signal set, remove redundant clearing of set, and do not save/restore errno around sigprocmask(SIG_SETMASK) - it never changes it. While at it, improve comments and make code style consistent across sleep.c file. text data bss dec hex filename - 242 0 0 242 f2 libc/unistd/sleep.o + 197 0 0 197 c5 libc/unistd/sleep.o Signed-off-by: Denys Vlasenko <dvlasenk@redhat.com>
