The default float type is not very useful but for the most basic applications.
For instance, as it is now, using the math package requires conversions for float
variables (the arguments for math functions are usually float64). Typical real
applications tend to specify the floating point precision required.

This proposal removes the predeclared types float and complex. Variable declarations
without type specification but with constant floating point or complex initializer
expressions will assume the type float64 or complex128 respectively.

The predeclared function cmplx is renamed to complex.

  number of full text results shown
- removed flag -fulltext; use -maxresults=0 to disable fulltext

- better indication on result page if not all results are shown

A query string of the form ident.ident will be used both as a qualified
identifier for identifier search and as a regular expression.
Qualified identifier lookup got broken accidentally when introducing
regexp full text search. Cleaned up surrounding logic a bit.

With the current implementation, xml unmarshalling
will silently fail to unmarshal any paths passing
through the same element, such as:

type T struct {
	A string "dummy>a"
	B string "dummy>b"
}

This change tweaks the algorithm so that this works
correctly.

Also, using paths that would cause the same element to
unmarshal twice will error out ahead of time explaining
the problem, rather than silently misbehaving.

When data is received for a channel, but that channel
is not ready to receive it, the central run() loop
is currently blocked, but this can lead to deadlock
and interference between independent channels.
This CL adds an explicit buffer size to netchan
channels (an API change) - the sender will not
send values until the buffer is non empty.

The protocol changes to send ids rather than channel names
because acks can still be sent after a channel is hung up,
we we need an identifier that can be ignored.

Minor cleanup:

  - added a function to remove repeated code
  - for consistency, replaced "return nil" with a panic at an
    unreachable point
