The net/http package supports setting the HTTP Authorization header
using the Basic Authentication Scheme as defined in RFC 2617, but does
not provide support for extracting the username and password from an
authenticated request using the Basic Authentication Scheme.
Add BasicAuth method to *http.Request that returns the username and
password from authenticated requests using the Basic Authentication
Scheme.

In CL 131450043, which raised it to 160,
I'd raise it to 192 if necessary.
Apparently it is necessary on windows/amd64.
One note for those concerned about the growth:
in the old segmented stack world, we wasted this much
space at the bottom of every stack segment.
In the new contiguous stack world, each goroutine has
only one stack segment, so we only waste this much space
once per goroutine. So even raising the limit further might
still be a net savings.
Fixes windows/amd64 build.

Actually it mostly deletes code -- alg.print and alg.copy go away.
There was only one usage of alg.print for debug purposes.
Alg.copy is used in chan.goc, but Keith replaces them with
memcopy during conversion, so alg.copy is not needed as well.
Converting them would be significant amount of work
for no visible benefit.

Signer is an interface to support opaque private keys.
These keys typically result from being kept in special hardware
(i.e. a TPM) although sometimes operating systems provide a
similar interface using process isolation for security rather
than hardware boundaries.
This changes provides interfaces for representing them and
alters crypto/tls so that client certificates can use
opaque keys.

Run it right before main.init.
There is still some runtime initialization that
happens before runtime.init, and some of that
may call into Go code (for example to acquire locks)
so this timing is not perfect, but I believe it is the
best we can do.
This came up because global variables intialized
to func values are done in the generated init code,
not in the linker.

As part of the translation of the runtime, we need to rewrite
C printf calls to Go print calls. Consider this C printf:
runtime·printf("[signal %x code=%p addr=%p pc=%p]\n",
g->sig, g->sigcode0, g->sigcode1, g->sigpc);
Today the only way to write that in Go is:
print("[signal ")
printhex(uint64(g->sig))
print(" code=")
printhex(uint64(g->sigcode0))
print(" addr=")
printhex(uint64(g->sigcode1))
print(" pc=")
printhex(uint64(g->sigpc))
print("]\n")
(That's nearly exactly what runtime code looked like in C before
I added runtime·printf.)
This CL recognizes the unexported type runtime.hex as an integer
that should be printed in hexadecimal instead of decimal.
It's a little kludgy, but it's restricted to package runtime.
Other packages can define type hex with no effect at all.
Now we can translate that original printf as the more compact:
print("[signal ", hex(g->sig), " code=", hex(g->sigcode0),
" addr=", hex(g->sigcode1), " pc=", hex(g->sigpc), "]\n")

ErrorContext now has all the information it needs from the Node,
rather than depending on the template that contains it. This makes
it easier for html/template to generate correct locations in its
error messages.
Updated html/template to use this ability where it is easy, which is
not everywhere, but more work can probably push it through.

Also fix a bunch of bugs:
1. Accesses to last_gc must be atomic (it's int64).
2. last_gc still can be 0 during first checks in sysmon, check for 0.
3. forcegc.g can be unitialized when sysmon accesses it:
forcegc.g is initialized by main goroutine (forcegc.g = newproc1(...)),
and main goroutine is unsynchronized with both sysmon and forcegc goroutine.
Initialize forcegc.g in the forcegc goroutine itself instead.

While here, OpenBSD's __tfork system call returns a pid_t which is an
int32 on all OpenBSD architectures, so change runtime.tfork's return
type from int64 to int32 and update the assembly implementations
accordingly.
