Unicode support
finish byte <-> utf8 and localencoding <-> utf8 conversions
- make substr($bytestr,0,0,$charstr) do the right conversion
add Unicode::Map equivivalent to core
add support for I/O disciplines
- a way to specify disciplines when opening things:
turn Cwd into an XS module? (Configure already probes for getcwd())
mmap for speeding up input? (Configure already probes for the mmap family)
sendmsg, recvmsg? (Configure doesn't probe for these but the units exist)
+ sockatmark?
setitimer, getitimer? (the metaconfig units exist)
