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.
