Issue Description:

In addition to CFFileDescriptor, which I requested in SR-8741, I've noticed three other missing classes in the public source drop. Since I don't know the reason for their omission, it's perfectly understandable if the answer to this is "sorry we can't release those" but I figured I'd ask 🙂

Here are the missing ones I'm noticing based solely on diffing the official CoreFoundation.h from the public repository (note that although the diffs are bigger than this, some of the missing #includes just haven't been added to CoreFoundation.h yet, but the files are in the repository; see #1691 for example):

• CFURLEnumerator

• CFFileSecurity

• CFStringTokenizer

These particular classes are almost entirely based on functionality which is actually not part of CF itself, so they may be difficult to port. We can keep around this request but it's less likely to happen than the one in SR-8741.

Yeah, that makes sense. I had a hunch these were a bit less likely than the other one 🙂

If I had to pick a priority for these though, from highest to lowest, I think it would be:

1. CFURLEnumerator

2. CFStringTokenizer

3. CFFileSecurity

This is mostly just based on informal perception of how widespread they are and how many things depend on things that depend on them. CFURLEnumerator for example is used by QT, which a lot of stuff depends on, so I care about it more 🙂

@parkera also, please let me know if would improve the likelihood of seeing any one of these if I create separate issues for each 🙂 I don't want someone willing to help seeing me ask for <easy thing> and <hard thing> at the same time and getting put off by <hard thing>

We can keep one bug for now, but make it clear here that we'll accept partial progress.
