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.

add UIO_MAXIOV macro in sys/uio.h while there's no POSIX namespace provision for UIO_* in uio.h, this exact macro name is reserved in XBD 2.2.2. apparently some glibc-centric software expects it to exist, so let's provide it.

remove LFS64 programming interfaces (macro-only) from _GNU_SOURCE these badly pollute the namespace with macros whenever _GNU_SOURCE is defined, which is always the case with g++, and especially tends to interfere with C++ constructs. as our implementation of these was macro-only, their removal cannot affect any existing binaries. at the source level, portable software should be prepared for them not to exist. for now, they are left in place with explicit _LARGEFILE64_SOURCE. this provides an easy temporary path for integrators/distributions to get packages building again right away if they break while working on a proper, upstreamable fix. the intent is that this be a very short-term measure and that the macros be removed entirely in the next release cycle.
