The two functions need to check whether they are called for a specific path
to implement the virtual mount point for the external storage. This
is statistically rare and a hit on the common case. Therefore speed up
the common case by performing integer comparision first, and only expensive
string construction and comparision if that succeeds.

A thread polls the appropriate GPIO pin for sd card presence and mounts
using the mount system call.

The external storage will be created during make install, as simext folder in
the build directory. Upon pressing the e key the sim will mount (virtually
) this into the root directory. It can be accessed in the same way as an
sd/mmc card on real targets. This requires quite some path trickery in io.c.

Part of this change is to align sdlapp builds to other application targets
in that the sim_* wrappers are not used anymore (except for sim_read/write).
Path mangling is now done in rbpaths.c as well.

The iocharset mount option names the codepages slightly differently and
must be translated properly.

The virtual external storage can be inserted/extracted with the e key. This
has little effect because there is no way to access the storage (yet, a later
commit will change this). Except on ondio where the mmc needs to be
extracted before entering USB (like on real target).

CONFIG_STORAGE & STORAGE_HOSTFS allows to use parts of the storage_* API to be
compiled for application targets without compiling storage.c or performing
actually raw storage access. This is primarily to enable application targets to
implement HAVE_MULTIVOMULE/HAVE_HOTSWAP (in a later commit).
SIMULATOR uses the same mechanism without explicitely defining STORAGE_HOSTFS
(how to add a bit to an existing preprocessor token?).

This driver will subsume the old button-lradc driver and support far more
options. It can sense LRADC channels, PSWITCH, GPIOs and it handles special
"buttons" like headphone insertion and hold detection. It also provides a
more natural description of the buttons using a target-defined table with some
macros to make it easy to read and write. It uniformely handles debouncing on
LRADC channels and PSWITCH.

On some OSes like Windows or if running in a virtual machine, the one second
timeout might be too short.

Original fix by Marcin: it had a problem because crt0 on imx233 is more
complicated than many targets: since we use virtual memory, we first disable
the MMU, then move the entire image (including init and itext stuff), then
setup a temporary stack to setup the MMU. Only when the MMU is enabled, can
we move the init and itext stuff to its right location and finally boot.
This requires some trickery because:
- the initial move copies everything, including init and itext
- the stack overlaps with init and itext to reclaim space
- the temporary stack cannot be the same as the main stack to avoid trashing
the init and itext code, also it needs to be a physical address

Rework the irq code, to put more code in the C part. When interrupt
nesting is enable, Rockbox gets pretty unstable so disable it for now.
