default features: make musl usable without feature test macros the old behavior of exposing nothing except plain ISO C can be obtained by defining __STRICT_ANSI__ or using a compiler option (such as -std=c99) that predefines it. the new default featureset is POSIX with XSI plus _BSD_SOURCE. any explicit feature test macros will inhibit the default. installation docs have also been updated to reflect this change.

improve ctype.h macros to diagnose errors the casts of the argument to unsigned int suppressed diagnosis of errors like passing a pointer instead of a character. putting the actual function call in an unreachable branch restores any diagnostics that would be present if the macros didn't exist and functions were used.

add macro version of ctype.h isascii function presumably internal code (ungetwc and fputwc) was written assuming a macro implementation existed; otherwise use of isascii is just a pessimization.
