standard API to syscall.Write, even on Windows where

The goal is to allow clients to distinguish function-local objects
from package-local objects and identify the specific function by
examining its scope. For example, a compiler may need to mangle
object names according to the outer function name.

go/types no longer reports a constant value for a slice,
e.g. []byte("foo").
ssa.Const no longer support slice constants, only
bool/string/numeric and nil.
emitConv emits a Convert instruction for string->[]byte
conversions.

The issue is addressed with the change in conversions.go.
Also:
- added corresponding API test
- made names for untyped ints, bools consistent with others
- use *Basic with names byte/rune instead of uint8/int32 for better output
- minor cleanups

Packages were not being created for all types.Packages,
specifically, indirectly imported packages were missing.
(*Program).CreatePackages now iterates over the type-checker's
package map too.
Also: removed all concurrency from importer. I think it was
incorrect (and hard to fix).
Also: change LoadInitialPackages so that all named packages
are loaded from source. This happens regardless of whether
GCImporter is used to satisfy imports.
Details:
- importer.Config.SourceImports flag determines whether to
load all packages from *.go source.
(Before, this was indicated by Config.Build != nil.)
- importer.Config.Build field effectively defaults to
&go/build.Default. A zero importer.Config is now usable.
- importer.Importer.Config field is now exported.
- LoadPackage renamed to ImportPackage since the resulting
packages may come from GCImporter (and be incomplete).
- doImport and ImportPackage fused.

Also report an error for "cross-interpretation": not supported
due to the interpreter's assumption that host and target
{int,uint,uintptr} are the same. (Too tedious and messy to fix.)
Tested manually:
% cat d.go
package main
const m = ^uintptr(0)
const w = m>>8&1 + m>>16&1 + m>>32&1
func main() { println(m, w) }
% ./ssadump -build=P -run d.go
package main:
const m m = 18446744073709551615:uintptr
const w w = 3:uintptr
18446744073709551615 3
% GOARCH=386 ./ssadump -build=P -run d.go
package main:
const m m = 4294967295:uintptr
const w w = 2:uintptr
Error: Cross-interpretation is not yet supported (target has GOARCH 386, interpreter has amd64).

This can import all of the standard library, and has been tested
by using gotype to type check libgo with gccgo's export data (this
would be nice to automate, but I can't see a good way to do it,
not least because system-specific source files cause errors which
I needed to identify manually).
It includes a builtin export locator. Unfortunately I can't see a
more reliable way to locate the builtin export files than to parse
the output of 'gccgo -###'.

(*CallCommon).Signature() now returns non-nil even for
built-ins. Builtins are now created with specialized types for
each use. Added sanity-check.
CallCommon.HasEllipsis field eliminated. It was an incorrect
memoization of Signature().IsVariadic() used only for
printing.
Also: introduce and use newTypeVar utility.

The display of search results can now be changed. A slice of functions for displaying the results can now be provided. By default, three functions are provided to display documentation, source code, and textual results.
This makes it possible to replace them with equivalents that, say,

Anonymous field names are emitted as "" in the export data
since the actual name can be reconstructed easily from the
field's type name. But "" names are not exported names and
thus the respective qualified name emits complete package
information even if the actual field name is exported. Fix
the package upon import.

The package of a struct field is independent of the type of the
struct field - the old code was technically not correct. That said,
it does not seem possible (or very difficult) to create a test case
because for exported anonymous fields that field package doesn't matter
(it's not needed for name identity), and non-exported anonymous fields
cannot be accessed from an imported package.

Although such a control-flow path is impossible by
