d63e84d2f7 fb: add fb_console_reserve_lines() 
This is like fb_console_scroll(), but only scrolls if necessary to
ensure that enough free space is available at the end of the console.
This avoids spuriously scrolling during shutdown if we still have space.

d73276b0bc tunables: add initial version. 
There are at least two types in the ADT related to USB,
but there's a decent chance that there are even more
required for other devices:

 * A simple tunable that applies to a whole device node
   and all its MMIO ranges specified in the "reg" property.
   This one seems to just be mask32.

 * A slightly more complex tunable that applies to a single
   MMIO range specified in the "reg" property. So far I've
   only seen 32 bit masks but the format looks like it should
   also support 8,16 and 64 bit masks.

efa4452a47 Fix libc header dependencies 
Turns out we had a bunch of silly dependencies on libc headers that are
not included with freestanding compilers. Fix all this and change the
CFLAGS to exclude libc headers and only include the built-in compiler
path.

Add our own versions of assert.h, errno.h, limits.h, and move malloc.h
and string.h together into a new path used as -isystem, so these headers
can be included using #include <>.

Remove a bunch of other dependencies in third-party code.

Add a strnlen function.

Disable building the libfdt overlay code for now, as it needs a strtoul
implementation. We can throw that in if/when we decide to use overlays.

b8349819fe Implement calling code as EL1 
This works by clearing HCR_EL2.TGE, and then doing essentially the same
thunk/return dance as for EL0 calls. However, since most EL1 exceptions
are not routed to EL2, we install hypercall vectors in EL1 to forward
them to EL2, and then short circuit the exception return to whatever
triggered the original exception.
