The general approach is to autoload rather than require, and to
require in the specific functions rather than the file.  (Bug#5642)

* url/url.el: Move mailcap require earlier in the file.

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

* gnus/gnus-util.el: Don't require time-date, netrc.
(message-fetch-field, gnus-group-name-decode): Declare rather than
autoloading.
(gnus-fetch-field): Require message.
(gnus-decode-newsgroups): Require gnus-group.

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

* gnus/message.el: Don't require hashcash, canlock, ecomplete.
Do require mail-utils.  Require nnheader only when compiling.
(smtpmail-default-smtp-server): Remove declaration.
(message-send-mail-function): Check smtpmail-default-smtp-server
is bound rather than requiring smtpmail.
(message-auto-save-directory, message-insert-signature): Use
expand-file-name rather than nnheader-concat.
(nnheader-insert-file-contents): Autoload.
(hashcash-wait-async): Declare.
(message-send-mail): Only call gnus-setup-posting-charset if
gnus-group-posting-charset-alist is bound.  Require hashcash if needed.
(message-send-mail-with-sendmail): Require sendmail.
(canlock-password, canlock-password-for-verify): Declare.
(message-canlock-password): Require canlock.
(nnheader-get-report): Autoload.
(gnus-setup-posting-charset): Declare.
(message-send-news): Require gnus-msg.
(message-make-references, message-make-in-reply-to): Use mail-header-id
rather than the alias mail-header-message-id.
(ecomplete-add-item, ecomplete-save): Declare.
(message-put-addresses-in-ecomplete): Require ecomplete.
(ecomplete-display-matches): Autoload.

* gnus/mm-decode.el: Don't require mailcap, gnus-util.
(gnus-map-function, gnus-replace-in-string, gnus-read-shell-command)
(message-fetch-field, mailcap-parse-mailcaps, mailcap-mime-info):
Autoload.
(mailcap-mime-extensions): Declare.

* gnus/mm-encode.el: Don't require mailcap.
(mailcap-extension-to-mime): Autoload.

* gnus/mml-sec.el: Don't require password-cache.

* gnus/mml.el (gnus-setup-posting-charset): Declare rather than autoload.
(mailcap-parse-mimetypes, mailcap-mime-types): Declare.
(mml-minibuffer-read-type): Require mailcap.
(mml-preview): Require gnus-msg.

* gnus/mml1991.el: Require password-cache.
(password-cache-expiry): Remove declaration.

* gnus/mml2015.el: Require password-cache.
(password-cache-expiry): Remove declaration.

* gnus/nneething.el (mailcap): Require mailcap.

* gnus/nnheader.el: (declare-function): Add compatibility stub.
(message-remove-header): Declare rather than autoload.
(nnheader-replace-header): Require message.

* gnus/rfc2047.el: Don't require qp.
