Move the logging mechanism to SAPI

Fixed SAPI modules to properly register their related modules.

Tried to centralize global variable registration as much as possible:

- Added $HTTP_ENV_VARS[] and $HTTP_SERVER_VARS[] support, which similarly
to $HTTP_GET_VARS[], contain environment

Tried to centralize global variable registration as much as possible:

- Added $HTTP_ENV_VARS[] and $HTTP_SERVER_VARS[] support, which similarly
to $HTTP_GET_VARS[], contain environment and server variables. Setting
register_globals to Off will now also prevent registration of the
environment and server variables into the global scope (Zeev)
- Renamed gpc_globals to register_globals (Zeev)
- Introduced variables_order that deprecates gpc_order, and allows control
over the server and environment variables, in addition to GET/POST/Cookies
(Zeev)

- Added flush() support to SAPI
- Got rid of the old flush() implemenetation in favour of the new one
- Added implicit_flush() support to the output buffering layer.
@- Added implicit_flu

@- Added implicit_flush() to control whether flush() should be called
@ implicitly after any output (Zeev)

Move reentrancy initialisation/destruction into SAPI.
These calls only do something, if reentrancy emulation is required.

Happy Y2K patch! Happy new year (or the new millennium, depending on whether
you start counting at 0 or 1).

Use sapi_module_struct to contain SAPI module name

(php_ns_request_handler) set SG(server_context) to non-NULL

Reapply configuration for each request

(php_ns_config) use 3.0's Ns_ConfigGetPath instead of Ns_ConfigPath

Output information about HTTP headers

- zend_file_handles must now flag whether their .filename property should be
free by Zend or not (uses e*() functions)

(php_ns_sapi_header_handler): use sapi_free_header()

Revert last patch (leak in libzend is fixed now)

Avoid fd leak which appears when using ZEND_HANDLE_FILENAME

Add reentrant versions of ctime, localtime, gmtime, asctime.

These cannot be implemented platform-independent, so we fall back to the native
non-reentrant versions, but lock during each

Add reentrant versions of ctime, localtime, gmtime, asctime.

These cannot be implemented platform-independent, so we fall back to the native
non-reentrant versions, but lock during each access (only if ZTS is used).

To initialize/destroy the used data structures, you need to call
reentrancy_startup() before sapi_startup(), and reentrancy_shutdown() after
sapi_shutdown().

(php_ns_hash_environment) Ns_ConnHost() may return NULL, check for it

(PHP getallheaders) added function for AOLserver

(php_ns_hash_environment) added REMOTE_PORT, SERVER_PORT, SERVER_NAME,
PATH_TRANSLATED, GATEWAY_INTERFACE variables

(php_ns_request_ctor) enable HTTP Access Authentication

(php_ns_hash_environment) supply PATH_TRANSLATED to scripts

(php_ns_hash_environment): provide more CGI/1.1 variables to scripts.

Added REQUEST_METHOD, QUERY_STRING, REMOTE_ADDR

(php_info_aolserver): add more information from the server context

(php_ns_hash_environment) add SERVER_SOFTWARE, SERVER_BOOTTIME, SERVER_BUILDDATE, SERVER_PROTOCOL
