wcwidth redeclaration

Build fails for git 1.5.1.3 on AIX, with the message:

utf8.c:66: error: conflicting types for 'wcwidth'
/.../lib/gcc/powerpc-ibm-aix5.3.0.0/4.0.3/include/string.h:266: error: previous declaration of 'wcwidth' was here

Fix this by renaming our static variant to our own name.
