feature test macros: make _GNU_SOURCE enable everything
previously, a few BSD features were enabled only by _BSD_SOURCE, not by _GNU_SOURCE. since _BSD_SOURCE is default in the absence of other feature test macros, this made adding _GNU_SOURCE to a project not a purely additive feature test macro; it actually caused some features to be suppressed. most of the changes made by this patch actually bring musl in closer alignment with the glibc behavior for _GNU_SOURCE. the only exceptions are the added visibility of functions like strlcpy which were BSD-only due to being disliked/rejected by glibc maintainers. here, I feel the consistency of having _GNU_SOURCE mean "everything", and especially the property of it being purely additive, are more valuable than hiding functions which glibc does not have.
