- implemented stand-alone Throttle mechanism
- added new flag -index_throttle to godoc
- index throttling enables index creation when running
godoc on app engine as it keeps godoc responsive

#include "go.h" (or "gg.h")
becomes
#include <u.h>
#include <libc.h>
#include "go.h"
so that go.y can #include <stdio.h>
after <u.h> but before "go.h".
This is necessary on Plan 9.

The following testcases now pass:
`<a href=x` tests that we do not error on partial unquoted attrs.
`<a href=x ` tests that spaces do end unquoted attrs on spaces.
`<a href=''` tests that we recognize the end of single quoted attrs.
`<a href=""` tests that we recognize the end of double quoted attrs.

My theory is that suse has larger TCP buffer sizes
by default. I now check over 100MB, rather than over 2MB.
100MB is ~halfway between the 1MB limit and the 200MB
request that's attempted.

It's a balance between fetching too much

The kludge is targeted at broken web browsers
like Chrome and IE, but it gets in the way of
sending 400 or 500-series error results with
formatted bodies in response to AJAX requests
made by pages executing in those browsers.
Now the AJAX cases will work and Chrome
and IE will be as broken with Go servers as
they are with all the other servers.
Fixes#2169.

CL 4938041 made some incorrect changes to the filter
function which caused a different doc/codelab/wiki/index.html
file to be generated.
Added FilterFileExports and FilterPackageExports function.
Same as the existing FileExpors/PackageExports functions
but using shared code. The old functions will be removed
in the next CL.

When a line directive was encountered we would push a new 'z' entry into
the history to indicate the start of new file attributation, and a 'Z'
entry to change line numbering. However we didn't pop the 'z' entry, so
we were actually corrupting the history stack. The most obvious
occurance of this was in the code that build the symbol tables for the
DWARF information - where an internal stack in the linker would overflow
when more than a few line directives were encountered in a single stack
(Issue 1878). So now we pop the 'z' entry when we encounter the end of
the file that the directive was in, which maintains the history stack
integrity.
Also, although new 'z' entries for new files had relative paths
expanded, the same was not done for line directives. Now we do it for
line directives also - so that the now correct DWARF information has the
full path available.
Fixes#1878.

Introduce extra scope for the variable declared by a
TypeSwitchGuard so that it doesn't conflict with vars
declared by the initial SimpleStmt of a type switch.
This is a replacement for CL 4896053 which caused
a build breakage.
Also:
- explicitly detect type switches (as opposed to detecting
expression switches and then do extra testing for type switches)
- fix all outstanding TODOs in parser.go
- ran all tests

This adds http.MaxBytesReader, similar to io.LimitReader,
but specific to http, and for preventing a class of DoS
attacks.
This also makes the 10MB ParseForm limit optional (if
not already set by a MaxBytesReader), documents it,
and also adds "PUT" as a valid verb for parsing forms
in the request body.
Improves issue 2093 (DoS protection)
Fixes#2165 (PUT form parsing)

Make the stack traces more readable for new
Go programmers while preserving their utility for old hands.
- Change status number [4] to string.
- Elide frames in runtime package (internal details).
- Swap file:line and arguments.
- Drop 'created by' for main goroutine.
- Show goroutines in order of allocation:
implies main goroutine first if nothing else.
There is no option to get the extra frames back.
Uncomment 'return 1' at the bottom of symtab.c.

The Go version has 64 character long section names; originally,
in Plan 9, the limit was 16. To provide compatibility, this
change allows the input length to be either the target length
or the earlier option. The section name is extended with spaces
where required.
This has been tested to work without regressions in the
Go environment, testing the older alternative has not been
possible yet.
