This doesn't account for the fact that getpwnam() isn't
thread-safe on FreeBSD; it also doesn't account for systems
where getpwnam_r lives outside of libc.

See thread with subject "[?PATCH?] using getpwnam_r in mod_userdir"
in Nov. 2000 new-httpd for some better long-term ideas for how to
handle the problem.

it allocates just that amount.  But, MM actually uses some of it, so we
need to over allocate just a bit.  On 32 bit machines 40 bytes is enough,
but on a 64 bit machine it isn't.  So, we bump it up to 80 bytes until
MM fixes this bug.

the hostname is interpolated into the filename, we need to be sure
that the result of interpolation doesn't expose parts of the
filesystem that should be private. This was done by checking the
syntax of the Host: header according to RFC 1123 and RFC 952. However,
many people have broken configurations that violate this syntax
(frequently because they use underscores in their names), and it also
doesn't accommodate the current effort to internationalize the DNS. I
don't think the former is a compelling reason to relax the syntax
checking, but the latter does justify this change.

The only RFC on internationalized DNS at the moment is RFC 2825 which
is an introduction to how difficult the whole thing is; the other
official documentation is a pile of Internet Drafts produced by the
Internationalized Domain Names Working Group of the IETF (with names
starting "draft-ietf-idn-"). However they have very little to say
about URIs, and the current Internet draft about internationalized
URIs (draft-masinter-url-i18n-05) has very little to say about
hostnames :-( On the gripping hand there is some useful information at
<http://www.apng.org/idns/> where there is some iDNS testbed work
going on. The basic idea is that although the format of the hostnames
in the DNS itself remains compatible with RFC 1123, the actual
hostname presented to the resolver is in UTF8, and therefore the
hostname in the URL and Host: header is also in UTF8.

This change relaxes the checking so that only character sequences that
are sensitive to the filesystem are rejected, i.e. forward slashes,
backward slashes, and sequences of more than one dot.

  Per new-httpd discussions, this version of mod_autoindex has been set
  aside as a test for rputs style backwards compatibility.  It has really
  horrid chunking charateristics, so it was the ideal nominee for the job.

  Please refer to src/modules/standard/mod_autoindex.c for the complete
  revision history.  When rputs is entirely eliminated (if it ever is)
  then this version should be eliminated.

the content-length has changed because some other filter changed the
length of the actual data.  We also ALWAYS want to calculate the content

if we decided to do so initially *and* we've seen all the data.

Prior to this change, for a http/1.1 request to mod_autoindex, the
unconditional call to ap_set_content_length() gave us the wrong
value (only taking into account the first brigade) and disabled
chunking.
