Pending issues for next release

[Rich Felker <dalias@aerifal.cx>]

Here's a quick list of open issues that we might want to take care of
before another release:

- ARM-optimized memcpy, etc.
- put*ent functions in pwd/shadow/etc.
- program_invocation_name
- Posssible misaligned access bugs in mbsrtowcs (?)
- [u]intmax_t underlying type mismatches ABI on 64-bit systems (?)
- dn_skipname
- switching libc.so/ld-musl.so symlink direction

And a few things that have been on the agenda but neglected for a long
time, which may stay that way unless anybody's excited about moving
them forward quickly:

- zoneinfo
- inet_makeaddr
- scanf %m modifier
- getifaddrs
- cpuset/affinity
- ether.h functions

We're well overdue for a release, so I'm hoping we can get one out
sometime this week. I'm going to be pretty busy next week so if not
this week it'll probably be two weeks out.
