fix assumption in fputs that fwrite returning 0 implies an error internally, the idiom of passing nmemb=1 to fwrite and interpreting the return value of fwrite (which is necessarily 0 or 1) as failure/success is fairly widely used. this is not correct, however, when the size argument is unknown and may be zero, since C requires fwrite to return 0 in that special case. previously fwrite always returned nmemb on success, but this was changed for conformance with ISO C by commit 500c6886c654fd45e4926990fee2c61d816be197.

fix multiple stdio functions' behavior on zero-length operations previously, fgets, fputs, fread, and fwrite completely omitted locking and access to the FILE object when their arguments yielded a zero length read or write operation independent of the FILE state. this optimization was invalid; it wrongly skipped marking the stream as byte-oriented (a C conformance bug) and exposed observably missing synchronization (a POSIX conformance bug) where one of these functions could wrongly complete despite another thread provably holding the lock.

clean up stdio_impl.h this header evolved to facilitate the extremely lazy practice of omitting explicit includes of the necessary headers in individual stdio source files; not only was this sloppy, but it also increased build time. now, stdio_impl.h is only including the headers it needs for its own use; any further headers needed by source files are included directly where needed.

use restrict everywhere it's required by c99 and/or posix 2008 to deal with the fact that the public headers may be used with pre-c99 compilers, __restrict is used in place of restrict, and defined appropriately for any supported compiler. we also avoid the form [restrict] since older versions of gcc rejected it due to a bug in the original c99 standard, and instead use the form *restrict.
