328. [func] Added isc_base64_decodestring().

Browse Source 
(This is basically bin/named/server.c:base64_cstring_tobuffer(), which I
will remove in another revision that will not need to be pulled up.  I also
would like to change isc_base64_totext() and isc_base64_tobuffer() to be
isc_base64_encoderegion() and isc_base64_decodelexer(), unless there are
exceptions.  I find their existing names to be quite confusing with regard to
what translation function each performs.)

328. [func] Added isc_base64_decodestring().
327. [bug] rndc.conf parser wasn't correctly recognising an IP
address where a host specification was required.
326. [func] 'keys' in an 'inet' control statement is now
required and must have at least one item in it.
warning is issued if a 'unix' control channel is
defined (not supported).
A "not supported" warning is now issued if a 'unix'
control channel is defined.
325. [bug] isc_lex_gettoken was processing octal strings when
ISC_LEXOPT_CNUMBER was not set.
