This replaces most the map[string][]string usage with
a new Values type name, with the usual methods.
It also changes client.PostForm to take a Values, rather
than a map[string]string, closing a TODO in the code.

This change was adapted from gccgo's libgo/runtime/mem.c at
Ian Taylor's suggestion. It fixes all.bash failing with
"address space conflict: map() =" on amd64 Linux with kernel
version 2.6.32.8-grsec-2.1.14-modsign-xeon-64.
With this change, SysMap will use MAP_FIXED to allocate its desired
address space, after first calling mincore to check that there is
nothing else mapped there.

Three optimizations: First, special-case power of two bases
that partion a Word(), bases 2, 4, 16, and 256. These can
be moved directly from internal Word() storage to the output
without multiprecision operations. Next, same approach for
the other power-of-two bases, 8, 32, 64, and 128. These
don't fill a Word() evenly, so special handling is needed
for those cases where input spans the high-bits of one Word
and the low bis of the next one. Finally, implement the
general case for others bases in 2 <= base <= 256 using
superbases, the largest power of base representable in a
Word(). For base ten, this is 9 digits and a superbase of
10^9 for 32-bit Words and 19 digits and 10^19 for 64-bit
compiles. This way we do just 1/9th or 1/19th of the expensive
multiprecision divisions, unpacking superdigits using fast
native machine arithmetic. The resulting code runs 7x to
800x the speed of the previous approach, depending on the
length of the number to be converted--longer is relatively
faster.
Also, extended the tests and benchmarks for string to nat
(scan()) and nat to string (string()) functions. A further
enhancement awaits the next CL to make general cases about
7x faster for long cases.

Programs expect that Read and Write are synchronous.
The background goroutines make the implementation
a little easier, but they introduce asynchrony that
trips up calling code. Remove them.

add QuoteToASCII.
The Quote and QuoteRune functions now let printable
runes (as defined by unicode.IsPrint) through. When
true 7-bit clean stuff is necessary, there are now two
new functions: QuoteToASCII and QuoteRuneToASCII.
Printf("%q") uses Quote. To get the old behavior, it
will now be necessary to say
Printf("%s", strconv.QuoteToASCII(s))
but that should rarely be necessary.

Also remove use of vector; a slice works fine - although
it's an unusual one.

This change moves a number of common PKIX structures into
crypto/x509/pkix, from where x509, and ocsp can reference
them, saving duplication. It also removes x509/crl and merges it into
x509 and x509/pkix.
x509 is changed to take advantage of the big.Int support that now
exists in asn1. Because of this, the public/private key pair in
http/httptest/server.go had to be updated because it was serialised
with an old version of the code that didn't zero pad ASN.1 INTEGERs.

This is in preparation of escape analysis; function parameters
can now be tagged with interesting bits by the compiler by
assigning to n->note.
tested by having typecheck put a fake tag on all parameters of
pointer type and compiling the tree.

The LDREXD and STREXD instructions require
aligned addresses, and the ARM stack is not
guaranteed to be aligned during the check.
This may cause other problems later (on the ARM
not all 64-bit pointers may be 64-bit aligned)
but at least the check is correct now.
