Via Russ Ross' bug report on golang-nuts, it was not possible
to send an HTTP request with a zero length body with either a
Content-Length (it was stripped) or chunking (it wasn't set).
This means Go couldn't upload 0-length objects to Amazon S3.
(which aren't as silly as they might sound, as S3 objects can
have key/values associated with them, set in the headers)
Amazon further doesn't supported chunked uploads. (not Go's
problem, but we should be able to let users set an explicit
Content-Length, even if it's zero.)
To fix the ambiguity of an explicit zero Content-Length and
the Request struct's default zero value, users need to
explicit set TransferEncoding to []string{"identity"} to force
the Request.Write to include a Content-Length: 0. identity is
in RFC 2616 but is ignored pretty much everywhere. We don't
even then serialize it on the wire, since it's kinda useless,
except as an internal sentinel value.
The "identity" value is then documented, but most users can
ignore that because NewRequest now sets that.
And adds more tests.

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.
