ffe83e582e 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

da4a22993e 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.

b817e97961 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).

1b14bdbf1c 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.

nacl support:
  * system calls, threading, locks.

586d9d5a19 use $(shell uname) instead of $GOOS when

this makes a cross-compiling (e.g., GOOS=nacl) build

fed4770685 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.

4a4ec23870 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
