When debugging snippets after M-x toggle-debug-on-error, errors in the
`post-command-hook' might cause `yas--post-command-handler' to be
removed. That's OK, always check that it's there before attempting any
`yas-expand-snippet' calls, since it is essential to check snippet
movement.
* yasnippet.el (yas-expand-snippet): Assert `yas-minor-mode' and
`yas--post-command-handler' active.
* yasnippet.el (yas--field-probably-deleted-p): Protect against
nil `yas--field-number'.
* yasnippet-tests.el (delete-numberless-inner-snippet-issue-562): New test
The main thrust is to get rid of the use of the `cl-struct-slots'
property which doesn't exist in Emacs-25 any more.
* yasnippet.el: Update copyright

`yas--make-blank-template' to `yas--make-template'

Collect some conventions about contributing to Yasnippet (which have
been scattered amongst various issues/pull request) into a single file.

Clarify what happens with yas-new-snippet.
Added more detail about how yas-new-snippet behaves,
particularly how it guesses a directory to save in.
* doc/snippet-development.org (Quickly finding snippets):
enhance section.
* yasnippet.el (yas--fallback): let-bind yas-fallback-behavior to
'yas--fallback before actually doing the fallback. Signal an error if
it's 'yas--fallback (indicating we're in an infinte loop).

load time from `load-file-name'.

local and call `yas--load-pending-juts' in all those at the end.
* yasnippet.el (cl-lib): Don't need `eval-and-compile'.
