Subject: [PATCH v2] headers_install.pl: autoconvert asm/inline/volatile to __xxx__

Headers in userspace should be using the __xxx__ form of the asm, inline,
and volatile keywords.  Since people like to revert these things without
realizing what's going on, have the headers install step autoconvert these
keywords.

v2
	- get asm/volatile to actually work ... i missed this due to other
	  local patches.  "asm volatile" should get fixed now.
