Rich Felker 3d7e32d28d 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.

Rich Felker 2ca55a93f2 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.

Szabolcs Nagy b04971d91a add inline isspace in ctype.h as an optimization
isspace can be a bottleneck in a simple parser, inlining it
gives slightly smaller and faster code

src/locale/pleval.o already had this optimization, the size
change for other libc functions for i386 is

Rich Felker c1a9658bd1 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.

Rich Felker 419ae6d5c9 support _BSD_SOURCE feature test macro
patch by Isaac Dunham. matched closely (maybe not exact) to glibc's
idea of what _BSD_SOURCE should make visible.

Rich Felker 7e14ed1360 fix ctype macros to cast argument to (unsigned) first
issue reported by nsz, but it's actually not just pedantic. the
functions can take input of any arithmetic type, including floating
point, and the behavior needs to be as if the conversion implicit in
the function call took place.

Rich Felker 74eea628cf extensive header cleanup for standards conformance & correctness
thanks to Peter Mazinger (psm) for pointing many of these issues out
and submitting a patch on which this commit is loosely based
