8cdee891d7 fmt: handle precision 0 format stings in standard way 
The C-stdlib heritage of printf/fprintf/sprintf has two odd
aspects for precisions of zero with integers. First, the zero
can be specified in any of these ways, "%4.0d", "%.0d" and
"%.d" which was not previously supported here. Secondly, the
seemingly universal interpretation of precision for integers
is that precision==0 and value==0 means print nothing at all.
The code here now handles this for integers just as the code
in big/int.c does the same for the Int type. New tests are
added to fmt_test.go to verify these changes.

This simplifies the API and makes it easier to make the template

5a141064ed html: parse misnested formatting tags according to the HTML5 spec. 
This is the "adoption agency" algorithm.

The test case input is "<a><p>X<a>Y</a>Z</p></a>". The correct parse is:
| <html>
|   <head>
|   <body>
|     <a>
|     <p>
|       <a>
|         "X"
|       <a>
|         "Y"
|       "Z"

1. SudoG always contains a pointer to the element
(thus no variable size, and less copying).
2. chansend/chanrecv allocate SudoG on the stack.
3. Copying of elements and gorotuine notifications
are moved out of critical sections.

ba2e3af177 ld: remove overlap of ELF sections on dynamic binaries 
The dynamic ELF sections were pointing to the proper data,
but that data was already owned by the rodata and text sections.
Some ELF references explicitly prohibit multiple sections from
owning the same data, and strip behaves accordingly.

The data for these sections was moved out and their ranges are
now owned by their respective sections.  This change makes strip
happy both with and without -s being provided at link time.

A test was added in debug/elf to ensure there are no regressions
on this area in the future.

Fixes #1242.
Fixes #2022.

NOTE: Tested on Linux amd64/386/arm only.

b546f50716 runtime: make goc2c build on Plan 9 
pkg/runtime/Makefile:
. Adjusted so "goc2c.c" is built using the Plan 9 libraries.

pkg/runtime/goc2c.c:
. Added/subtracted #include headers to correspond to Plan 9
  toolkit.
. Changed fprintf(stderr,...)/exit() combinations to
  sysfatal() calls, adjusted the "%u" format to "%ud".
. Added exits(0) at the end of main().
. Made main() a void-returning function and removed the
  "return 0" at the end of it.

Tested on UBUNTU and Plan 9 only.

f1df07bf6a 5l, 6l, 8l: Add a PT_LOAD PHDR entry for the PHDR. 
Per the TIS ELF spec, if a PHDR entry is present in the
program header table, it must be part of the memory image of
the program. Failure to do this makes elflint complain, and
causes some tools that manipulate ELF to crash.

- suppress the print that -help is not defined.
- return a special error code if -help is set
- do not change behavior if an explict "help" flag is defined.

87d9e7e166 image: change Pix[0] to mean top-left corner of an image's Rect instead 
of the origin.

image/png and image/jpeg benchmarks show no significant changes.

The image/draw changes suggest to me that making a gofix for this is not
feasible. People are just going to have to make manual fixes.

b053400e37 http: update triv.go with gofix 
Sample code in triv.go wouldn't compile because it didn't use the new
FileSystem interface.
This was discussed on golang-nuts on July 7.

3987b91213 exp/template: better template invocation 
1) Make the value optional ({{template "foo"}})
2) Allow the template identifier to be a thing of type *Template.
The second makes it easy to drop templates in to a set dynamically
during invocation.
