Allows the developer to pass a map either by itself for
evaluation, or inside a struct. Access to data inside
maps is identical to the current system for structs, ie.
-Psuedocode-
mp map[string]string = {
"header" : "A fantastic header!",
"footer" : "A not-so-fantastic footer!",
}
template.Execute(mp)
...can be accessed using {header} and {footer} in
the template. Similarly, for maps inside structs:
type s struct {
mp map[string]string,
}
s1 = new s
s1.mp["header"] = "A fantastic header!";
template.Execute(s1)
...is accessed using {mp.header}. Multi-maps, ie.
map[string](map[string]string) and maps of structs
containing more maps are unsupported, but then, I'm
not even sure if that's supported by the language.
Map elements can be of any type that can be written
by the formatters. Keys should really only be strings.

Previously a netFd could be queued for reading/writing in the channel,

Error information is carried from RPC server to client in the string
'Error' field of rpc.Response. An empty string is sent in the success

We are dealing with the multiplicative group ℤ/pqℤ. Multiples of
either p or q are not members of the group since they cannot have an
inverse. (Such numbers are 0 in the subgroup ℤ/pℤ.)
With p and q of typical size (> 512 bits), the probability of a random
blind [1..pq-1] being a multiple of p or q is negligible. However, in
the unit tests, much smaller sizes are used and the event could occur.
This change checks the result of the ext GCD and deals with this case.
It also increases the size of p and q in the unit test as a large
number of the keys selected were p, q = 227,169.

added new net.PacketConn interface for packet protocols.
implemented proper UDP listener.
cleaned up LocalAddr/RemoteAddr methods - cache in netFD.
threw away various unused methods.
an interface change:
introduced net.Addr as a network address interface,
to avoid conversion of UDP host:port to string and
back for every ReadFrom/WriteTo sequence.
another interface change:
since signature of Listener.Accept was changing anyway,
dropped the middle return value, because it is available
as c.RemoteAddr(). (the Accept signature predates the
existence of that method.)
Dial and Listen still accept strings, but the proto-specific
versions DialTCP, ListenUDP, etc. take net.Addr instead.
because the generic Dial didn't change and because
no one calls Accept directly (only indirectly via the http
server), very little code will be affected by these interface
changes.
design comments welcome.

Firstly, with -Werror, GCC switched to printing warnings starting
with "error:". Widening the string matches solves this as the messages
are otherwise unchanged.
Secondly, GCC 4.4 outputs DWARF sections with with NUL bytes in all
the offsets and requires the relocation section for .debug_info to be
processed in order to result in valid DWARF data. Thus we add minimal
handling for relocation sections, which is sufficient for our needs.
