wfDl() is a wrapper around dl(), which is an evil function and
basically only works from the command line of Zend. Luckily
no extension has ever used this thing, so let's just remove it
outright.
For comparison, here's a list of places it does not work:
- hhvm
- php as apache module
- php compiled with zts support
- safe_mode
- Basically any shared host that cares about security
Most callers are using it to check for extension support and are
actually failing gracefully when wfDl() returns false. In these
places we're just going to use extension_loaded().
While we're at it, clean up some of the test skip logic in the
media tests so we can bail as early as possible if we know we
can't complete the test.
This also immediately removes $wgLoadFileinfoExtension. It's been
enabled by default since 5.3 and falls back gracefully when the
support isn't available.

First letters are supposed to be primary collation elements.
However, we do not want expansions to be considered
as firstletters (aka thorn "þ" -> "th" which isn't
the same as any other first letter (since "t" !== "th" )
however if þ was a first letter, the word "the" and
even worse the word "too" would be sorted under it, which
is wrong.
Looking for feedback if this all sounds sane. I have tested
it, it got rid of the contractions while at the same time
not removing any letter it wasn't supposed to.
Once this is merged, we could get rid of all the
-<langcode> entries. The other firstLetter array
entries for tailorings could be merged into
generateCollationData.php too, since incorrect
things would get pruned automatically, which
would probably make the logic in Collation.php
simpler.
