 Stop message.el from loading about 40 libraries it doesn't always need.
 The general approach is to autoload rather than require, and to
 require in the specific functions rather than the file.  (Bug#5642)

 * gmm-utils.el: Don't require wid-edit.
 (widget-create-child-value, widget-convert, widget-default-get):
 Autoload.

 (message-fetch-field, gnus-group-name-decode): Declare rather than
 autoloading.
 (gnus-fetch-field): Require message.
 (gnus-decode-newsgroups): Require gnus-group.

 * ietf-drums.el: Don't require time-date.

 * message.el: Don't require hashcash, canlock, ecomplete.
 Do require mail-utils.  Require nnheader only when compiling.

 expand-file-name rather than nnheader-concat.

 (hashcash-wait-async): Declare.

 gnus-group-posting-charset-alist is bound.  Require hashcash if needed.
