        src/lib/libc/string: strcspn.c strpbrk.c strspn.c

Log Message:
Replace O(nm) versions of strspn, strcspn and strpbrk with O(n+m)
implementations based on the suggestions I made for DragonFly's libc
ages ago. For charset with more than one entry and iterating over the
first two characters of s, this is consistently faster on amd64.
