musl 0.9.12 released

[Rich Felker <dalias@aerifal.cx>]

I'm pleased to announce musl 0.9.12, just barely on-schedule:

    Notable new features include zoneinfo timezone support, PIE
    support on all supported targets, simple heap-based buffer
    overflow detection in free/realloc, and mildly improved IPv6
    support. Various dynamic linker improvements have been made for
    arch variants and non-root installations. The C++ ABI is now
    stabilized and compatible with glibc's C++ ABI. Several major bugs
    have been fixed including a potentially-dangerous regression in
    scanf introduced in 0.9.11 that could pass invalid pointers to
    free, a flaw in dl_iterate_phdr's reporting of library headers
    that could crash C++ exception-handling, and longstanding integer
    overflows in time conversion code that produced incorrect results
    for certain pre-1935 dates. Other minor bugs have also been fixed.

Rather than the usual future-directions here, I'll follow up on the
roadmap thread/wiki.
