Move CVE information into advisories directory One of the requirements to becoming a CVE Numbering Authority (CNA) is to publish advisories. Do this by maintaining a file for each CVE fixed in the advisories directory in the source tree. Links to the advisories can then be shared as: https://sourceware.org/git/?p=glibc.git;a=blob_plain;f=advisories/GLIBC-SA-YYYY-NNNN The file format at the moment is rudimentary and derives from the git commit format, i.e. a subject line and a potentially multi-paragraph description and then tags to describe some meta information. This is a loose format at the moment and could change as we evolve this. Also add a script process-fixed-cves.sh that processes these advisories and generates a list to add to NEWS at release time.

getaddrinfo: Potential use-after-free
When an NSS plugin only implements the _gethostbyname2_r and
_getcanonname_r callbacks, getaddrinfo could use memory that was freed
during buffer resizing, potentially causing a crash or read or write to
arbitrary memory.
