Each package using struct field tags assumes that

This CL adds support in package reflect for sharing
tags between multiple packages. In this scheme, the

(raw strings help when writing that tag in Go source).

that returns the associated value.

I have written up a Marshal and MarshalIndent pair that should
closely reflect the way that Unmarshal works. I would love feedback
on making this code more accessible and efficient... I haven't used
reflecton on this scale before, so there is probably a lot of work
that can be done on that.
Some potentially controversial things:
- All tag names are lower-cased by default.
- Zero-valued struct values are skipped.
- No namespace prefix (o:tag, etc) mechanism is supplied.
- You are allowed to marshal non-struct values (even though unmarshal
cannot handle them).
- A tag for a non-XMLName struct field that isn't "attr", "chardata",
or "innerxml" is used as the name of the tag. This could wreak
havoc if you try to marshal a protobuf struct.
- The "innerxml" and "chardata" are inserted verbatim. If you try to
marshal something straight from unmarshal, the results could be
unexpected (remove "innerxml" support from Marshal would be one
possible solution).

This was also causing the reverse proxy problem where incoming

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.

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.

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.

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.

Using the getaddrinfo order is only okay if we
are smart enough to try multiple addresses in Dial.
Since the code does not do that, we must make
the right first choice, regardless of what getaddrinfo
does, and more often that not that means using the
IPv4 address, even on IPv6 systems. With the CL
applied, gotest fails in package net on OS X.

getaddrinfo() orders the addresses according to RFC 3484.
This means when IPv6 is working on a host we get results like:
[]string = {"2001:4810::110", "66.117.47.214"}
and when it's not working we get:
[]string = {"66.117.47.214", "2001:4810::110"}
thus can drop firstFavoriteAddr.
This also means /etc/gai.conf works on relevant systems.

This mostly adds the infrastructure for writing various forms of
packets as well as reading them. Adding symmetric encryption support
was simply an easy motivation.
There's also one brown-paper-bag fix in here. Previously I had the
conditional for the MDC hash check backwards: the code was checking
that the hash was *incorrect*. This was neatly counteracted by another
bug: it was hashing the ciphertext of the OCFB prefix, not the
plaintext.

On windows, the command line is passed as a single null-terminated string. While the automatic parameter escaping done by syscall.StartProcess works fine with most Windows programs, some applications do their own custom parsing of the command line, in which case the automatic escaping becomes harmful.

A FlagSet is an independent set of flags that may be used,
for example, to provide flag processing for subcommands
in a CLI. The standard, os.Args-derived set of flags is a
global but non-exported FlagSet and the standard functions
are wrappers for methods of that FlagSet.
Allow the programmer to control whether the program
exits if there is a parse error. For the default set, the behavior
remains to exit on error.
