Allows for several "connections" all resulting in
a single real connection that talks to the network.
Right now, nothing uses this though.

HttpContentLengthHeadZero - allow Content-Length of 0 to be returned on HEAD
HttpExpectStrict - allow admin to control whether we must see "100-continue"
This is helpful when using Ceph's radosgw and httpd.

This is a first stab, the checks will likely have to be revised.
For now, we check
* if the request line contains control characters
* if the request uri has fragment or username/password
* that the request method is standard or registered with RegisterHttpMethod
* that the request protocol is of the form HTTP/[1-9]+.[0-9]+,
or missing for 0.9
* if there is garbage in the request line after the protocol
* if any request header contains control characters
* if any request header has an empty name
* for the host name in the URL or Host header:
- if an IPv4 dotted decimal address: Reject octal or hex values, require
exactly four parts
- if a DNS host name: Reject non-alphanumeric characters besides '.' and
'-'. As a side effect, this rejects multiple Host headers.
* if any response header contains control characters
* if any response header has an empty name
* that the Location response header (if present) has a valid scheme and is
absolute
If we have a host name both from the URL and the Host header, we replace the
Host header with the value from the URL to enforce RFC conformance.
There is a log-only mode, but the loglevels of the logged messages need some
thought/work. Currently, the checks for incoming data log for 'core' and the
checks for outgoing data log for 'http'. Maybe we need a way to configure the
loglevels separately from the core/http loglevels.

This reverts r1407643, but changes the syntax of HttpProtocol to
min=0.9|1.0, which is less ambiguous than the previous +0.9|-0.9.
Allowing to configure an arbitrary version range was a bad idea,
because it only checked the version in the request line, without
affecting the semantics of the headers, etc.
A tighter restriction off the version in the request line is still
possible with <If "%{SERVER_PROTOCOL_NUM} ..."> .

excluded from this cleanup as they must be signature identical to the
clib functions, and although the definition of size_t has been flakey,
the definition of those functions appears to be generally clean since
ANSI C.

everywhere.
We know that the core module has module_index 0. Therefore we can save
some pointer operations in ap_get_module_config(cv, &core_module) and
ap_set_module_config(cv, &core_module, val). As these are called rather often,
this may actually have some (small) measurable effect.

and context document root (which is the file system directory that
this URL prefix is mapped to). This generalization of the document
root makes it easier for scripts to create self-referential URLs and
to find their files.
- Expose CONTEXT_DOCUMENT_ROOT and CONTEXT_PREFIX as envvars, in mod_rewrite,
and in ap_expr.
- Make mod_alias and mod_userdir set the context information.
- Allow to override the document root on a per-request basis. This allows
mass vhosting modules to set DOCUMENT_ROOT correctly.
- Make mod_vhost_alias set the per-request document root
PR: 26052, 46198, 49705
Remaining tasks:
- Use the context document root & prefix in mod_rewrite to make RewriteBase
unneccessary in many cases. Do this without breaking compatibility.
- Write docs.

EXEC_ON_READ phase.

This makes <If> apply to all requests, not only to file base requests and
it allows to use <If> inside <Directory>, <Location>, and <Files> sections.
The merging of <If> sections always happens after the merging of <Location>
sections, even if the <If> section is embedded inside a <Directory> or
<Files> section.
