Switch ogle over to the in-tree debug/proc package. Fix
debug/proc to install to the right place. Delete the old
ptrace package. The diff looks huge, but it's mostly
s/ptrace/proc/.
Fix declared and not used errors and unused import errors in
the interpreter and update code to use ast.BasicDecl and
multi-type switch. There are still a lot of "switch _ :=
x.(type)" that should make use of the new type switch syntax,
but those will be a different CL.
change code font to "monospace", which will
let the browser use the font the user has set up
as the default fixed-width font, instead of forcing Courier.
also set the size to 100%, which means 100% of the
font size in the surrounding text. this looks a little
better in the main body but much better when the
code is in a heading (like Package unsafe).
changes to accommodate nacl:
* change ldt0setup to set GS itself; nacl won't let us do it.
* change breakpoint to INT $3 so 8l can translate to HLT for nacl.
* panic if closure is needed on nacl.
* do not try to access symbol table on nacl.
* mmap in 64kB chunks.
use $(shell uname) instead of $GOOS when
deciding what the host process support is.
this makes a cross-compiling (e.g., GOOS=nacl) build
still generate valid host debugger binaries.
nacl:
add jmp to constant pc.
generate HLT for INT $3
do not insert NOPs between REP/REPN and subsequent instruction.
allow very long time for convergence.
convert 386 to use %gs instead of %fs for extern register.
required for nacl and may be nicer for ffi,
because %gs is the standard register for thread-local storage.

step 2 of the great buffer shift.
make strings.Buffer handle strings and bytes with comparable efficiency.
if ok, next step will be to move this code to bytes.Buffer and terminate
strings.Buffer's short happy life.
8l: step toward native client.
- ELF header bits and addresses
- do not let instructions span 32-byte boundary
- align CALLs so return is to 32-byte boundary
- align indirect jump targets to 32-byte boundary
(only possible indirect jumps are function entries)
still to do:
- replace indirect jump, indirect call, and ret with
nacl-approved instruction sequences
- switch to GS segment for m-local storage

A step towards "externalizing" some Go docs.
+ style sheet: like code.google.com but less feature-ful
+ JS with table-of-contents generation
+ tweaked go_spec.html and go_mem.html to use new style+JS
+ static-HTML-ified a few other Go docs:
+ static HTML versions of some wiki pages (which I'll turn
into links to these pages).
A notable thing that is _not_ in this changelist: any change
to the godoc tool or whatever thing generates http://go/godoc
first step toward cgo tool.
can extract import "C" doc comment
