194e105784 From Ilya Dogolazky ilya.dogolazky at teleca dot fi: 
The new algorithm does not use any array initialisation.
Instead of that the only integer variable "index" is initialized.
It is not using any bitwise operations and shifts as well.

The well-known algorithm (an efficient representation for sparse sets) is
mentioned as exercise 2.12 in "The Design and Analysis of Computer Algorithms"
by Alfred Aho, John Hopcroft and Jeffrey Ullman. It is described here
http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.30.7319
and here

b5174f925f SUSv3 says, wcwidth(wc) returns: 
1) wc is nul wide-character, return 0.
  2) wc is printable wide-character, return column width.
  3) else, return -1.
but our implementation, case 3) returns 0. it's wrong!

9acf218ba1 Before using the slightly more involved bitmap tables, 
check that the charset for strspn/strcspn is non-trivial.
An empty charset is either a direct return or a strlen and
a single charset a simple loop.

2ca83a6a31 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.

e3361bb265 Add strsep(3) to libkern. 
To avoid code duplication, move strsep.c to the kernel/userland
common files.

Soon I will commit source-address selection (options IPSELSRC).
It will use strsep(3).
