The gccgo compiler does not provide a gc-style GOROOT with standard
library sources. The effect is that guru may not fully work when using
gccgo. However, it can fully work if the GOROOT environment variable
points to valid gc-style GOROOT. In that case, make it work by telling
the go/build package to use gc mode.

Global, package-level queries can be done without typechecking.
This makes it significantly cheaper.
Instead of typechecking, consider all packages that directly
import the query package. In each of those packages, filter out:
* files that don't contain the query name
* files that don't import the query package
Fully parse the remaining files and look for selector expressions
matching the query package and name.
There are a few twists (dot imports, the query package, xtests).
They are described, along with how they are handled,
in the large comment at the beginning of globalReferrersPkgLevel.
On my machine and GOPATH, this reduces typical time
needed to find referrers to encoding/json.MarshalIndent
from (roughly)
real 0m39.946s
user 2m27.844s
sys 0m54.774s
to (roughly)
real 0m5.687s
user 0m15.793s
sys 0m16.001s
The processing of packages could be parallelized;
that is left for a future change, to ease reviewing.
Benefits from that will be limited;
building the reverse import graph accounts for 73%
of the runtime, and that is dominated by syscalls.

Previously, goyacc's line number tracking would run off by one whenever
a multiline comment was used inside of an action, like so:
expr:
TOKEN
{
/* Hello. */
}
This is because the character after the multi-line comment close marker
(i.e., the character immediately after `*/`) was blindly printed out
instead of properly accounted for. A newline character after a
multi-line comment would fail to increment lineno, for example, and any
error messages generated after that point would refer to the wrong line.
Similarly, a variable reference after a multi-line comment, like
$$.val = &someStruct{Value: /* oops */$1}
would copy the $ literally into the resulting Go code. (This was not a
problem in practice because multi-line comments are typically followed
by whitespace.)
Adjust the control flow so the character after the multi-line comment
close marker character gets run through the relevant switch statement
and accounted for.

Before this change, findImportGoPath used a field within the
(otherwise read-only) structs in the dirScan map to cache the distance
from the importing package to the candidate package to be imported. As
a result, the top-level imports.Process function was not safe to call
concurrently: one goroutine could overwrite the distances while
another was attempting to sort by them. Furthermore, there were some
internal write-after-write races (writing the same cached distance to
the same address) that otherwise violate the Go memory model.
This change fixes those races, simplifies the concurrency patterns,
and clarifies goroutine lifetimes. The functions in the imports
package now wait for the goroutines they spawn to finish before
returning, eliminating the need for an awkward test-only mutex that
could otherwise mask real races in the production code paths.

Currently, links inside blog articles are absolute links to golang.org.
But when a godoc server is run locally, the blog package should
serve local links pointing to the local godoc server. It is not possible
to simply change the links inside the blog templates to relative urls
because the blog articles are independant pages on their own.
And moreover, they are served from blog.golang.org.
Rather, the blog package consumes and serves blog articles.
So, a flag was added in the Config struct to denote whether
to convert the links or not. This flag is then set from the
call site in godoc package where the blog server is initialized from.
This was required because "golang.org/x/tools/blog" is a package
which can be used by other code to serve blog pages and not just godoc.
This preserves existing functionality for all working code which
imports "golang.org/x/tools/blog" and changes the functionality only
when a godoc server is run locally.

This CL groups the package list into two groups - standard library(GOROOT),
and third-party code(GOPATH).
It also wraps the list with a collapsible div header used in the package
documentation page. This makes the entire page easy to view and manage, and also
makes it consistent with the rest of the pages.
To implement this, a new function was added to the filesystem interface
which returns the root type of the filesystem. In most cases, it is either GOROOT
or GOPATH. There are other kinds of filesystems which are not used in the home page,
so additional values have been added to satisfy the interface.
A side effect of this is that the html template code has become a bit spaghetti-like
with if conditions all over. This is because the same template is used to render
a package directory as well as the package home page. A better way is to use
two separate templates for the different tasks. This cleans out a lot of the
if conditions and make for a much cleaner code. This has been taken care in CL 101295.
