- Mark getc() as inline, this has no effect on gcc but helps clang.
- Move getc() body before xgetc() so gcc does not emit a warning about
function having no body.
This patch shrinks boot2 a little.
o It switches kname to be just a pointer instead of an array.
o It changes ioctl to unsigned from uint8_t.
o It changes the second keyhit limit to 3 seconds from 5.
o It removes bi_basemem/bi_extmem/bi_memsizes_valid setting.
In sys/boot/i386/boot2/boot2.c, change the type of the 'opts' variable
from uint16_t back to uint32_t. The actual option bitmasks (RB_* and
RBX_*) assume at least a 32 bit variable.

and sys/boot/pc98/boot2, do not simply assign 'gcc' to CC, since compile
flags are sometimes passed via this variable, for example during the
build32 stage on amd64. This caused the 32-bit libobjc build on amd64
to fail.
Instead, only replace the first instance of clang (if any, including
optional path) with gcc, and leave the arguments alone.

It's based on the newest i386's one and has the advantage of:
- ELF binary support.
- UFS2 filesystem support.
- Many FreeBSD slices support on a disk.

Bonus: including kern.mk just to pick kernel warning flags
was an extremely bad idea anyway, because it also picked
up CFLAGS (it probably wasn't the case at the time of CVS
rev. 1.1, I haven't checked). Remove duplicate CWARNFLAGS
from CFLAGS.

order to resolve the conflict.
to get the physical address doesn't work for all values of KVA_PAGES,
while masking 8 MSBs works for all values of KVA_PAGES that are
multiple of 4 for non-PAE and 8 for PAE. (This leaves us limited
with 12MB for non-PAE kernels and 14MB for PAE kernels.)
To get things right, we'd need to subtract the KERNBASE from the
virtual address (but KERNBASE is not easy to figure out from here),
or have physical addresses set properly in the ELF headers.

are no longer limited to a virtual address space of 16 megabytes,
only mask high two bits of a virtual address. This allows to load
larger kernels (up to 1 gigabyte). Not masking addresses at all
was a bad idea on machines with less than >3G of memory -- kernels
are linked at 0xc0xxxxxx, and that would attempt to load a kernel
at above 3G. By masking only two highest bits we stay within the
safe limits while still allowing to boot larger kernels.

which is set only when MNT_ASYNC is set and mnt_noasync is zero, and
check that flag instead of MNT_ASYNC before initiating async io.

Move the remaining bits of <sys/diskslice.h> to <i386/include/bootinfo.h>
Move i386/pc98 specific bits from <sys/reboot.h> to
<i386/include/bootinfo.h> as well.
Adjust includes in sys/boot accordingly.
