This is sorta an optimisation, and sorta a bug fix. In one
test case I have available, it can speed a page build up from 3
minutes to 3 seconds.
The root of the problem is that $links{$page} contains arrays of
links, rather than hashes of links. And when a link is found,
it is just pushed onto the array, without checking for dups.
Now, the array is emptied before scanning a page, so there
should not be a lot of opportunity for lots of duplicate links
to pile up in it. But, in some cases, they can, and if there
are hundreds of duplicate links in the array, then scanning it
for matching links, as match_link and some other code does,
becomes much more expensive than it needs to be.
Perhaps the real right fix would be to change the data structure
to a hash. But, the list of links is never accessed like that,
you always want to iterate through it.
I also looked at deduping the list in saveindex, but that does
a lot of unnecessary work, and doesn't completly solve the problem.
So, finally, I decided to add an add_link function that handles deduping,
and make ikiwiki-transition remove the old dup links.
if suitable alternate text is unknown, then it should not be given.
empty alt text is suitable mainly for purely decorative images.

I think this used to be a fatal error, not just inline error, so I don't
know why it was never noticed, but if a page that an img directive mentions
gets deleted, bestlink() returns a file that no longer exists, and
srcfile() throws an error.
Note that bestlink's behavior of returning a deleted file could be
considered buggy. But, if it's changed to not do that, the page with the img
on it is not updated at all when the file is removed.
destpage does not normally need to be worried about when creating other files
as part of the process of rendering a page. Using destpage results in
inlined pages creating two copies of such files. It works to not use destpage
in this case because the inlining page depends on the source page, so if the
source page is modified or deleted the inlining page will be updated.
set to the destination page. This avoids need for hacks to munge the urls
in preview mode, which fixes several bugs.

old files.
* Change where the img plugin puts scaled images. It's better to make the
scaled images subpages of the page that embeds them, rather than putting
them alongside the original image, since if two pages scale the same image
the same way, this prevents complications in dealing with two pages
creating the same file. The move will be handled transparently, though you
might want to rebuild your wiki to make it occur in one step.
for extended pagespecs. The old calling convention will still work for
back-compat for now.
* The calling convention for functions in the IkiWiki::PageSpec namespace
has changed so they are passed named parameters.
* Plugin interface version increased to 2.00 since I don't anticipate any
more interface changes before 2.0.
previous ugly hack used to avoid writing rss feeds in previews.
* Fix the img plugin to avoid overwriting images in previews. Instead it
does all the work to make sure the resizing works, and dummys up a resized
image using width and height attributes.
* Also fixes img preview display, the links were wrong in preview before.
