This is to make it easier to support Solaris syslog.  On
Solaris syslog messages are sent via STREAMS using putmsg to
/dev/conslog.  The putmsg call uses a a control buffer of type
log_cdtl and a data buffer which is the message, and it is in
general a big mess.  This CL just splits out the Unix domain
support so that Solaris can use a different mechanism.  I do
not propose to implement the Solaris support today.  This
split will make it possible for gccgo to just call the libc
function for now.

The Flush functionality wasn't removed, but now you have
to test if your ResponseWriter is also a Flusher:

func ServeHTTP(rw http.ResponseWriter, req *http.Request) {
   if f, ok := rw.(http.Flusher); ok {
       f.Flush()
   }
}

When writing custom scanners, I found that
Token itself was rarely useful, as I did not always

Caller code needs to change:

rw.SetHeader("Content-Type", "text/plain")
to:
rw.Header().Set("Content-Type", "text/plain")

This now permits returning multiple headers
with the same name using Add:

rw.Header().Add("Set-Cookie", "..")
rw.Header().Add("Set-Cookie", "..")

This patch also fixes serialization of headers, removing newline characters.

Fixes the broken linux/amd64 build.
The symbol table, itself a symbol, was having
its size rounded up to the nearest word boundary.
If the rounding add >7 zero bytes then it confused
the debug/gosym symbol table parser.  So you've
got a 1/8 chance to hit the bug on an amd64 system.

Just started in the recent change because I fixed
the rounding to round to word boundary instead
of to 4-byte boundary.

Much of the bulk of Go binaries is the symbol tables,
which give a name to every C string, Go string,
and reflection type symbol.  These names are not worth
much other than seeing what's where in a binary.

This CL deletes all those names from the symbol table,
instead aggregating the symbols into contiguous blocks
and giving them the names "string.*", "go.string.*", and "type.*".

Before:
$ 6nm $(which godoc.old) | sort | grep ' string\.' | tail -10
  59eda4 D string."aa87ca22be8b05378eb1c71...
  59ee08 D string."b3312fa7e23ee7e4988e056...
  59ee6c D string."func(*token.FileSet, st...
  59eed0 D string."func(io.Writer, []uint8...
  59ef34 D string."func(*tls.Config, *tls....
  59ef98 D string."func(*bool, **template....
  59effc D string."method(p *printer.print...
  59f060 D string."method(S *scanner.Scann...
  59f12c D string."func(*struct { begin in...
  59f194 D string."method(ka *tls.ecdheRSA...
$

After:
$ 6nm $(which godoc) | sort | grep ' string\.' | tail -10
  5e6a30 D string.*
$

Those names in the "Before" are truncated for the CL.
In the real binary they are the complete string, up to
a certain length, or else a unique identifier.
The same applies to the type and go.string symbols.

Removing the names cuts godoc by more than half:

-rwxr-xr-x 1 rsc rsc 9153405 2011-03-07 23:19 godoc.old
-rwxr-xr-x 1 rsc rsc 4290071 2011-03-07 23:19 godoc

For what it's worth, only 80% of what's left gets loaded
into memory; the other 20% is dwarf debugging information
only ever accessed by gdb:

-rwxr-xr-x 1 rsc rsc 3397787 2011-03-07 23:19 godoc.nodwarf
