Moved the details of how to read a directory
and how to parse the results behind the new
syscall functions ReadDirent and ParseDirent.

Now os needs just one copy of Readdirnames
for the three Unix variants, and it no longer
imports "unsafe".

- used to be only for standard log, not for user-built.
- there were no getters.
Also rearrange the code a little so we can avoid allocating
a buffer on every call.  Logging is expensive but we should
avoid unnecessary cost.

This should have no effect on existing code.

This CL includes a gofix module and full code updates: all.bash passes.
(There may be a few comments I missed.)

The interesting packages are:

        os

Amazon S3 sends Transfer-Encoding "chunked"
on its 404 responses to HEAD requests for
missing objects.

We weren't ignoring the Transfer-Encoding
and were thus interpretting the subsequent
response headers as a chunk header from the
previous responses body (but a HEAD response
can't have a body)

A connection shouldn't be made available
for re-use until its body has been consumed.

(except in the case of pipelining, which isn't
implemented yet)

This CL fixes some issues seen with heavy load
against Amazon S3.

Subtle implementation detail: to prevent a race
with the client requesting a new connection
before previous one is returned, we actually
have to call putIdleConnection _before_ we
return from the final Read/Close call on the
http.Response.Body.

According to RFC 3986: "For consistency, URI producers
and normalizers should use uppercase hexadecimal digits
for all percent-encodings."  Using lower case characters
makes it incompatible with Google APIs when signing OAuth requests.
