#196535 by sun, chx, dww: check whether Drupal can issue HTTP requests at all, so we know that this is the cause of problems, not the remote host not responding.

 - whitespaces at end of lines
 - indentation
 - control structure usage
 - whitespace in empty lines
 - phpdoc comment formatting

- Patch #137138 by jvandyk: fixed problem with drupal_http_request() not setting the proper error code when a network effect occurs.  Causes the XML-RPC backend to fail.

/me looks down
OH MY GOD... I'M MELLLLTTIIINNGG NOOOOOOO.... AAARGHHHHHH.

Oh well, don't the people inside the asylum say the outside world is insane, too?

   * xmlrpc_value_calculate_type() fails for empty arrays
   * PHPDoc for xmlrpc_value_calculate_type()
   * use is_*() instead of gettype() as advised in the PHP manual (and document this)
   * coding style

- Patch #7458 by chx: merged the XML-RPC multicall support into xmlrpc() and use lazy-loading for the XML-RPC libraries.(performance improvement).

- Patch #28482 by Uwe: add CVS $Id$ tags to all source files in Drupal core. This allows admins to know exactly which version of which files they use. In addition I want to use CVS $Id$ tags in my upcoming security.module to check for possible vulnerabilities. That's not possible if some files simply don't have $Id$s.

Note: I also (mostly) unified the tags to use the "// ID" form instead of "/* ID */", but that's more of a cosmetic issue. I'm not sure whether *.txt files and the stuff in themes/ need tags(?).

- Patch #11728 by Uwe Hermann: fixed some typos in the code comments, Doxygen documentation and screen output.

  Uwe: I dropped the 'iff' chunks as 'iff' stands for 'if and only if'.

/**
 * Wrapper around xml_parser_create() which extracts the encoding from the XML
 * data first and sets the output encoding to UTF-8. This function should be
 * used instead of xml_parser_create(), because PHP's XML parser doesn't check
 * the input encoding itself.
 *
 * This is also where unsupported encodings should be converted.
 * Callers should take this into account: $data might have been changed after
 * the call.
 *
 * @param $data The XML data which will be parsed later.

- Fixed a weird typo introduced by the <b> -> <strong> patches and indented
  the code a bit better.

- Committed a slightly modified version of Slavica's table prefix patch.

- Renamed 'xmlrpc_decode' to '_xmlrpc_decode' to avoid redeclaration when
  PHP's XML-RPC library is enabled.

- Renamed 'xmlrpc_encode' to '_xmlrpc_encode' to avoid redeclaration when
  PHP's XML-RPC library is enabled.

- Removed 'if (funcion_exist("xmlrpc_encode"))' check from common.inc.

- Patch by Ulf: XHTML-ified the code.

- removed references to $this->user() from themes.
- removed $BaseTheme->user(). It was deprecated a while back.

NOTE: this update will break custom themes, so make sure you update your
themes before updating!

- Upgraded the XML-RPC libraries to the latest version as suggested by
  Julian.

  passing them that way.
