Issue 3207 was caused by setting GOPATH=GOROOT.
This is a common mistake, so diagnose it at command start
and also correct the bug that it caused in get (downloading
to GOROOT/src/foo instead of GOROOT/src/pkg/foo).
Issue 3268 was caused by recognizing 'packages' that
had installed binaries but no source. This behavior is not
documented and causes trouble, so remove it. We can
revisit the concept of binary-only packages after Go 1.

Factored the error synchronization code into two functions
syncStmt and syncDecl. Because they may return w/o advancing
the scanner, there is potential for endless loops across
multiple parse functions; typically caused by an incorrect
token list in these functions (e.g., adding token.ELSE to
syncStmt will cause the parser to go into an endless loop
for test/syntax/semi7.go without this mechanism). This would
indicate a compiler bug, exposed only in an error situation
for very specific source files. Added a mechanism to force
scanner advance if an endless loop is detected. As a result,
error recovery will be less good in those cases, but the parser
reported a source error already and at least doesn't get stuck.

This moves the various CA root fetchers from crypto/tls into crypto/x509.
The move was brought about by issue 2997. Windows doesn't ship with all
its root certificates, but will instead download them as-needed when using
CryptoAPI for certificate verification.
This CL changes crypto/x509 to verify a certificate using the system root
CAs when VerifyOptions.RootCAs == nil. On Windows, this verification is
now implemented using Windows's CryptoAPI. All other root fetchers are
unchanged, and still use Go's own verification code.
The CL also fixes the hostname matching logic in crypto/tls/tls.go, in
order to be able to test whether hostname mismatches are honored by the
Windows verification code.
The move to crypto/x509 also allows other packages to use the OS-provided
root certificates, instead of hiding them inside the crypto/tls package.

in the TCP/IP stack somewhere. (Ironically, most of these

Before:

The mechanism used is a <meta> tag in the HTML document
retrieved from fetching:
https://<import>?go-get=1 (preferred)
http://<import>?go-get=1 (fallback)
The meta tag should look like:
<meta name="go-import" content="import-alias-prefix vcs full-repo-root">
The full-repo-root must be a full URL root to a repository containing
a scheme and *not* containing a ".vcs" qualifier.
The vcs is one of "git", "hg", "svn", etc.
The import-alias-prefix must be a prefix or exact match of the
package being fetched with "go get".
If there are multiple meta tags, only the one with a prefix
matching the import path is used. It is an error if multiple
go-import values match the import prefix.
If the import-alias-prefix is not an exact match for the import,
another HTTP fetch is performed, at the declared root (which does
*not* need to be the domain's root).
For example, assuming that "camlistore.org/pkg/blobref" declares
in its HTML head:
<meta name="go-import" content="camlistore.org git https://camlistore.org/r/p/camlistore" />
... then:
$ go get camlistore.org/pkg/blobref
... looks at the following URLs:

Ultimately it finds, at the root (camlistore.org/), the same go-import:
<meta name="go-import" content="camlistore.org git https://camlistore.org/r/p/camlistore" />
... and proceeds to trust it, checking out git //camlistore.org/r/p/camlistore at
