Merge the x1000 and jz47xx exception handling code since they use
the same exception vectors and handlers. The interrupt handler is
now called from the common exception vector, but remains separate
for each board since they have different IRQ layouts.
The new exception handler can provide a stack traceback from the
interrupted code, rather than the (uninteresting) caller traceback
displayed by panicf. This allows you to see what led up to a null
pointer deref or division by zero, which makes it _much_ easier to
track down errors that occur in common leaf functions like strcmp.

The abiflags data is only used to communicate ABI information to a
program loader -- you can see what info is stored with readelf -A.
Dropping it shaves 24 bytes off of every binary (including plugins).

Using a macro to put each function in its own .icode-based section
allows us to put the functions in IRAM _and_ have linker GC. This
removes a troublesome #ifdef BOOTLOADER_SPL on the X1000 target.

Main/IRQ from: 7.5/0.75 to: 7.25/1.0
With the reduction of the opus codec stack usage, giving the IRQ stack
some additional breathing room is now possible.

New amounts:
7.50K main stack
0.75K irq stack
Prior values of 8K+1K overflowed IRAM by ~660 bytes on Onda 7x7 targets,
but worked on the xDuoo X3.
(The discrepancy is due to the Onda targets having more LCD code shoved
into IRAM.)

Cleaned up, rebased, and forward-ported from the xvortex fork.

Vectors are needed by the CPU, but they don't need to be accessed by Rockbox.
Without the KEEP(), they can be removed when liking with --gc-sections,
creating a broken binary without any warnings. This tells the linker to not
remove them. It should enable use of --gc-sections for all targets. When not
using --gc-sections, this does not change the binary.

This is related to gdb, and gdb can only work on SH and ifp
This was mistakenly kept when app.lds was forked for each SoC
Side-effect: fix DEBUG builds when the rockbox binary is expected to
be loaded at the start of DRAM and there is no runtime relocation

* Add initial RoLo support
* Don't enable IRAM in plugins for now
* Initial try at getting PCM working (doesn't crash anymore at least)
* Replace hard-coded constant with #define in usb-jz4740
