<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Hm. I thought we got rid of this on purpose, since the ao2_alloc_options of the framed object already provides it a ref count of 1.
Who decrements the allocation reference?</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">We did remove it by mistake. After format_cap_framed_init we need framed to have 2 references. The one we add here belongs to the cap->formats list, the other (from ao2_alloc) belongs to cap->preference_order.
These two references are removed when the format is removed from the cap. See format_cap_destroy or ast_format_cap_remove for example, the frame is decremented when removed from the cap->formats and cap->preference_order. This without this reference I'm adding back in we get a frack for every format added to a cap.</pre>

* chan_mgcp: buf unused variable prevents devmode build
* chan_skinny / chan_unistim: tech.capabilities double ao2_cleanup
* format_cap: ao2_ref(framed, +1) was mistakenly removed, causing many fracks
In the case of format_cap, I didn't notice that it was being added to a cap->formats and caps->preference_order.</pre>
