Updated all cross-platform functions and types up to 8 June 2016

I have not updated two OSX-specific functions,

uiDarwinMarginAmount() and uiDarwinPaddingAmount().

I'm not exactly sure how this should be done.

Sorry about it being in multiple commits. Also, the previous pr (I closed) did not update, so I made a new one. My apologies.

• git rebase -i origin/master
• don't touch the first line.
• from line 2 to last line replace all the pick by fixup.
• save and then push with -f.
