Previously comparisons with NaN led to contradictory results if it was
compared to anything not NaN, since Less always returned false, thus
breaking monotonicity of ordering.
This fix makes NaN less than anything else and adds NaN and (+-)Inf to
testcases.

Replace cas with xadd in scheduler.

Verified with Promela model.
When there's actual contention for the atomic word,
this avoids the looping that compare-and-swap requires.

This is the last piece (I hope) of the set creation code.
These helpers create sets from files containing individual
template definitions, free of {{define}} clauses. This
design is helpful if the templates live one per file,
undecorated.

Also:
- Add parser.SpuriousError flag. If set, the parser reports all (including
spurious) errors rather then at most one error per line.
- Add -e flag to gofmt and gotype: If set, gofmt and gotype report all
(including spurious) errors rather than at most one error per line.
- Updated the respective documentation.

Now handles standard precision specifications, standard interactions of
redundant specifications (such as precision and zero-fill), handles the
special case of precision specified but equal to zero, and generates the
output without recursive calls to format/printf to be clearer and faster.

ServeMux depends on having a URL
in order to mux. It might be that the right
fix is to have CONNECT handlers just not
look at URL.

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.

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.
