Replace memcpy and sprintf with smart_strs.

Combine all HTTP headers into a single writev

- Fix copyright notices with 2001

If we cannot send the header, we don't need to continue with the page.

Include <sys/uio.h>. Apparently, the header cleanup in glibc 2.2.2
caused that file to be included by accident.

Save 50% of the syscalls when writing the HTTP header.

Especially on FreeBSD it seems to be common that send(2) does not
do a decent job. We handle that better now.

Propagate the response code/HTTP status code back to thttpd for logging.

Account the number of sent bytes properly

Many patches. I hope I remember them all:

- Make sapi_module available to external modules (PHPAPI)
- Make the php.ini path reported in phpinfo() always point to
real full path of

Many patches. I hope I remember them all:

- Make sapi_module available to external modules (PHPAPI)
- Make the php.ini path reported in phpinfo() always point to
real full path of the php.ini file
- Optimized the ISAPI module not to read unnecessary server
variables and read necessary variables at most once.

Add thttpd-dependent interface for maintaining persistent connections on
an iterative web-server. This will be used by the IRCG extension.

Fix aborted connection handling and stop modifying thttpd data

Add/unify aborted connection handling

Leave initializing of auth_(user|password) to php_handle_auth_data().

Use php_handle_auth_data

Provide basic auth info to scripts.

Protect shutdown handler from being called multiple times.

Restore the headers_only test to the centralized SAPI startup. If necessary, it can
be overriden in the activate() callback.

Set SG(request_info).path_translated to the path of the main script.

Compute absolute path to script

Use request_uri as PHP_SELF. decodedurl also includes the query string.

php_register_variables(.. ELS_CC ..)

Make proper use of SAPI's register_environment functionality.

Fix zend_fiel_handle handling. Should fix URL include
and various opened_path inconsistencies.

Heads up! I have moved the headers_only and response_code checks out of
SAPI and down into the individual SAPI modules. I have made the
appropriate changes in all the SAPI modules, but please verify these.
The reason for this change is that Apache sometimes will feed PHP
a request_method of GET but have r->header_only set to true. This happens
in an ErrorDocument redirect. In this same scenario we want to preserve
the status code as well instead of just overwriting it with a 200 and
losing this information. For now the other sapi modules act exactly as
before since they probably do not make this distinction, and they may
not even have a valid response code this early in the request.
@ Fix HEAD request bug on an Apache ErrorDocument redirect and preserve
@ the status code across the redirect as well. (Rasmus)
