 This patch includes several improvements to the wxr importer:

 * The code for handling author names and mapping them to local user names
 is refactored and simplified.  The old code was copied straight from the
 MT importer; the new version is easier to follow and runs faster on sites
 with large user tables.

 * Gzipped files are supported if zlib is available (this fixes one half of
 #5485).

 * There's a simple check to confirm whether or not the file appears to be
 the correct format.  An error is displayed if it is not.  Previously the
 importer would silently ignore a file if it was the wrong format.

 * Filters are added to make it possible to turn off the ability to add new
 users and download files.  There's also a filter for specifying a maximum
 size for attachment imports.  These are mainly of interest for wpmu.

 * Failed attachment downloads are removed.

 * The uploaded import file is given a '.import' extension.

 * import_start and import_end actions are added.
