Core:EXTLINUX: convert the getfssec function to C
the main file read function (getfssec) has been converted to
C. Fow now, abort 90% stuff have been converted to C. The
next is to clean the code and convert the rest.

Core: Convert the searchdir function to C
for now, almost all the stuff related to EXT have been converted to C,
and fow my (limit) test, it works well.
The getfssec function haven't converted to C, because it also be called
from asm file, and I find it's a bit hard to convert it to C. But however,
it's my next plan.

core: prevent buggy INT 13h from leaving IF=0
If it can happen for CD-ROM BIOSes, it can probably happen elsewhere,
too; make sure we don't leave interrupts disabled after broken INT 13h
calls.

The two functions are converted to C.
And for another thing, I find that I haven't included the load_config.c file before(my fault),
so added it here.

simple menu: make ONTIMEOUT work with MENU HIDDEN
The command invoked when no keys were pressed for the specified time
(ONTIMEOUT) may be different from the menu item initially selected
when the menu is displayed (DEFAULT or MENU DEFAULT). Unfortunately,
this did not work together with MENU HIDDEN (which is exactly the case
when having a separate ONTIMEOUT command makes the most sense).
