Florian Weimer cb4692ce1e libio: asprintf should write NULL upon failure 
This was suggested most recently by Solar Designer, noting
that code replacing vsprintf with vasprintf in a security fix
was subtly wrong:

  Re: GStreamer Security Advisory 2024-0003: Orc compiler
  stack-based buffer overflow
  <https://www.openwall.com/lists/oss-security/2024/07/26/2>

Previous libc-alpha discussions:

  I: [PATCH] asprintf error handling fix
  <https://inbox.sourceware.org/libc-alpha/20011205185828.GA8376@ldv.office.alt-linux.org/>

  asprintf() issue
  <https://inbox.sourceware.org/libc-alpha/CANSoFxt-cdc-+C4u-rTENMtY4X9RpRSuv+axDswSPxbDgag8_Q@mail.gmail.com/>

I don't think we need a compatibility symbol for this.  As the
GStreamer example shows, this change is much more likely to fix bugs
than cause compatibility issues.
