cmd/go: respect $GOBIN always

Before, we only consulted $GOBIN for source code
found in $GOROOT, but that's confusing to explain
and less useful.  The new behavior lets users set
GOBIN=$HOME/bin and have all go-compiled binaries
installed there.

Fixes #3269.

Undo CL 5783076 and apply correct fix.

The /doc hack is wrong.  The code to handle this case was
already there and just needs a simple fix:

 	// We didn't find any directories containing Go files.
 	// If some directory returned successfully, use that.
-	if len(all) == 0 && first != nil {
+	if !haveGo {
 		for _, d := range first {
 			haveName[d.Name()] = true
 			all = append(all, d)

For people untarring with -p or as root, preserving file permissions.
This way we don't make tars owned by adg/eng or adg/staff or whatever
machine Andrew was on. Instead, we always build tarballs owned by predictable
users.

Except archive/tar doesn't seem to work.

Use archive/zip instead of 7z on Windows.

Look for all Windows deps before starting build, and include looking

their PATHs.

files.

     As we've dropped support for Mac OS X 10.5, I think the generated .pkg
     should reflect that decision.
     But this CL make it impossible to generate pkg on Mac OS X 10.6, at least
     for me.

The generated syscall files for Windows are still breaking "go tool api"
(unknown function []byte); I'll look at fixing that separately.

1) The -D argument should always be a pseudo-import path,
like _/Users/rsc/foo/bar, never a standard import path,
because we want local imports to always resolve to pseudo-paths.

2) Disallow local imports in non-local packages.  Otherwise
everything works but you get two copies of a package
(the real one and the "local" one) in your binary.

To make sure that there is no resource leak,
I suggest to fix the 'fakedb' driver such as it fails when any
Stmt is not closed.
First, add a check in fakeConn.Close().
Then, fix all missing Stmt.Close()/Rows.Close().
I am not sure that the strategy choose in fakeConn.Prepare/prepare* is ok.
The weak point in this patch is the change in Tx.Query:
  - Tests pass without this change,
  - I found it by manually analyzing the code,
  - I just try to make Tx.Query look like DB.Query.

In a transaction, on a Stmt.Query error, it was possible for a
connection to be added to a db's freelist twice. Should use
the local releaseConn function instead.

Thanks to Gwenael Treguier for the failing test.

Also in this CL: propagate driver errors through releaseConn
into *DB.putConn, which conditionally ignores the freelist
addition if the driver signaled ErrBadConn, introduced in a
previous CL.

We should check the CRC32s of files on EOF, even if there's no
data descriptor (in streamed files), as long as there's a non-zero
CRC32 in the file header / TOC.

We now always write the "optional" streaming data descriptor
signature, which turns out to be required for OS X.

Also, handle reading the data descriptor with or without the
signature, per the spec's recommendation. Fix data descriptor
reading bugs found in the process.
