Change request: SELinux tweaks.

[Luke Macken]

Attached are some patches that will fix many AVC's that are currently
happening within our infrastructure.

Patch 0010-Fix-our-semanage_fcontext-function-to-work-on-symlin.patch
/should/ fix the problem introduced in
41acfbc83c80d12d915a0d6087e841aba2c7e78c that caused restorecon to flip
out when trying to apply context to a symlink.

The rest should all be fairly straight-forward fixes that involve
flipping booleans, setting context, and creating custom policy modules.
Apologies for the binary blobs in the diffs :)
