When writing custom scanners, I found that
Token itself was rarely useful, as I did not always
want to stop at white space. This change makes
it possible to stop at any class of characters
while reusing the buffer within State.

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

The parser populates all scopes for a given file (except
type-related scopes for structs, interfaces, and methods
of types) at parse time.

A new parser flag, DeclarationErrors, enables error messages
related to declaration errors (as far as it is possible to
provide them).

The resulting AST has all (non-field, non-method) identifiers
resolved that can be resolved w/o doing imports or parsing
missing package files.

The ast.File node contains the (partially complete)
package scope and a list of unresolved global identifiers.

All type-specific data structures have been removed from the AST.

The existing typechecker is functional but needs to be adjusted
(simplified) accordingly. Utility functions to resolve all
identifiers for a package (after handling imports and parsing
all package files) are  missing.

Unrelated changes:
- Rename typechecker/testdata files to that they are not considered
  by gofmt.
- Minor cleanups/simplifications.

Parses all .go files in src and misc without declaration errors.
Runs all tests. Changes do not affect gofmt output.

In June 2010 I accidentally checked in pending
changes to package rpc in a compiler CL:
https://golang.org/cl/1736041

I backed them out by hand in a followup CL:
https://golang.org/cl/1736042

That followup CL missed the lines being deleted
in this CL, spotted by Petar.

hg diff -r 5678:5683 src/cmd/prof/gopprof \
        src/pkg/image/png/reader.go \
        src/pkg/rpc/client.go \
        src/pkg/rpc/jsonrpc/all_test.go \
        src/pkg/rpc/jsonrpc/server.go \
        src/pkg/rpc/server.go \
        test/arm-pass.txt

confirms that these lines in server.go are the
only ones that were missed by the original followup.

Fixes #1583.
