[waffle] [PATCH 0/3] Memory leak fixes

[Emil Velikov]

Spotted while searching for a severe memory corruption under wgl.
Did not manage to find it yet, although notices these bad boys.

I will case the corruption bug over the next few days + cleanup&split
the patches hopefully I will see what's going wrong, or perhaps
someone will be kind enough to point out what I'm doing wrong :)

AFAICS the user is supposed to explicitly release the current context
using waffle_make_current(dry, NULL, NULL), is that correct ?

Patches are based on top of the for-upstream-2.1 branch.

Thanks
Emil
