Apply a similar transformation to %+v that we did to %#v, making it
a top-level setting separate from the + flag itself. This fixes the
appearance of flags in Formatters and cleans up the code too,
probably making it a little faster.

The %#v verb is special: it says all values below need to print as %#v.
However, for some situations the # flag has other meanings and this
causes some issues, particularly in how Formatters work. Since %#v
dominates all formatting, translate it into actual state of the formatter
and decouple it from the # flag itself within the calculations (although
it must be restored when methods are doing the work.)
The result is cleaner code and correct handling of # for Formatters.
TODO: Apply the same thinking to the + flag in a followup CL.
Also, the wasString return value in handleMethods is always false,
so eliminate it.

This is a minor cleanup following CL 142360043:
The internal parse and format functions in both packages
were almost identical - made them identical by adding an
extra parameter, and documented them as identical.
Eventually we should find a nice way to factor these functions
out, but we cannot do this now while in prep for 1.4.

Not a language change.
Several inaccuracies were fixed:
1) A variable declaration may declare more than just one
variable.
2) Variable initialization follows the rules of assignments,
including n:1 assignments. The existing wording implied a 1:1
or n:n rule and generally was somewhat unspecific.
3) The rules for variable declarations with no types and
untyped initialization expressions had minor holes (issue 8088).
4) Clarified the special cases of assignments of untyped values
(we don't just have untyped constants, but also untyped bools,
e.g. from comparisons). The new wording is more direct.
To that end, introduced the notion of an untyped constant's
"default type" so that the same concept doesn't have to be
repeatedly introduced.

Right now it is always pkgname.test.exe, but if pkgname is
patch or install or setup or update, Windows thinks that
running it will install new software, so it pops up a dialog
box asking for more permission.
Renaming the binary avoids the Windows security check.
This only applies to the binary that the Go command writes
to its temporary work directory. If the user runs 'go test -c'
or any of the other ways to generate a test binary, it will
continue to use pkgname.test.exe.

Update #8798
This is a new implementation of pprof,
written in Go instead of in Perl.
It was written primarily by Raul Silvera and
is in use for profiling programs of all languages
inside Google.
The internal structure is a bit package-heavy,
but it matches the copy used inside Google, and
since it is in an internal directory, we can make
changes to it later if we need to.
The only "new" file here is src/cmd/pprof/pprof.go,
which stitches together the Google pprof and the
Go command libraries for object file access.
I am explicitly NOT interested in style or review
comments on the rest of the files
(that is, src/cmd/pprof/internal/...).
Those are intended to stay as close to the Google
copies as possible, like we did with the pprof Perl script.
Still to do:
- Basic tests.
- Real command documentation.
- Hook up disassemblers.

For Go 1.3 these external packages were collapsed into
large single-file implementations stored in the cmd/objdump
directory.
For Go 1.4 we want pprof to be able to link against them too,
so move them into cmd/internal, where they can be shared.
The new files are copied from the repo in the file path (rsc.io/...).
Those repos were code reviewed during development
(mainly by crawshaw and minux), because we knew the
main repo would use them.

See comment 4 of https://code.google.com/p/go/issues/detail?id=8483#c4:
"So if a user creates a http.Client, issues a bunch of
requests and then wants to shutdown it and all opened connections;
what is she intended to do? The report suggests that just waiting for
all pending requests and calling CloseIdleConnections won't do, as
there can be new racing connections. Obviously she can't do what
you've done in the test, as it uses the unexported function. If this
happens periodically, it can lead to serious resource leaks (the
transport is also preserved alive). Am I missing something?"
This CL tracks the user's intention to close all idle
connections (CloseIdleConnections sets it true; and making a
new request sets it false). If a pending dial finishes and
nobody wants it, before it's retained for a future caller, the
"wantIdle" bool is checked and it's closed if the user has
called CloseIdleConnections without a later call to make a new
request.
