fc2480da3c goinstall: write to goinstall.log in respective GOPATH
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).

480ef72c23 sort: fixed bug in (Float64Slice) Less; NaN less than anything else
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.

Fixes #2092.

2d972ad493 exp/template: construct sets from plain template files
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,

dcef981217 godoc/httpzip.go: use correct path in Readdir
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

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.
