Undo CL 4254056 now that enough time has elapsed
that people with old trees have all built and removed
those files (which are no longer generated in that location).

. By defining getcallerpc(x) as __builtin_return_address(0)
here, it becomes possible to use the Plan 9 compatible form
when compiling using GCC. The alternative is to add conditional
compilation based on the compiler identity in "cmd/8g/gsubr.c"
to distinguish between the two cases.

goinstall: report every newly installed package to the dashboard
This makes "goinstall -a" work on systems with GOROOTs that are
not user-writable, as is the case with Debian's Go packages.
This also makes goinstall.log the canonical list of installed
packages, in that only packages new to goinstall.log are reported to
the dashboard.
A side-effect is that writing to goinstall.log is now mandatory.
(A bug in the original implementation meant this was the case, anyway.)
The principal benefit of this change is that multiple packages from the
same repository can now be reported to the dashboard. It is also less
likely for a user to report multiple installations of the same package
to the dashboard (they would need to remove the package from
goinstall.log first).

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.

Fixes a problem where Readdir would always return
empty directories (Readdir is only called by godoc
if the usual directory handler is commented out
in godoc.go, and if a zip file system is provided;
thus, this bug never manifested itself in godoc).
Also:
- better choice of variable/field names
- simplified error handling a bit
- better comments

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.

look at URL.
