Adhemerval Zanella cf11e74b0d wcsmbs: Ensure wcstr worst-case linear execution time (BZ 23865) 
It uses the same two-way algorithm used on strstr, strcasestr, and
memmem.  Different than strstr, neither the "shift table" optimization
nor the self-adapting filtering check is used because it would result in
a too-large shift table (and it also simplifies the implementation bit).

Checked on x86_64-linux-gnu and aarch64-linux-gnu.
