WT-2691 Use wrappers for ctype functions to avoid sign extension errors (#2818)
* Cast arguments for ctype functions to avoid sign extension errors.
Create __wt_* versions of all ctype functions, and use them whenever
wt_internal.h is available. Add check to prevent direct use of ctype functions
from core source.
* Change wrappers to use u_char arguments, and return bool.
Remove unused wrappers.
* Use u_char in preference to unsigned char.
* Examples do not have u_char defined on Windows.
