GXemul Code2

Adding "trace" versions of SuperH bsr and bsrf_rn instructions. Adding the first SuperH instruction combination for speeding up a variable read loop (bt_samepage_wait_for_variable).

Fixing bug at end of address space, which caused symbols to not show up.

Adding missing Dreamcast entry.

Better reset of graphics during "switch to bootstrap 1" in Dreamcast fake ROM emulation.

Show symbols in more cases than before.

Adding Dreamcast devices as symbols, so that runtime debugging will show meaningful names instead of just addresses, when reading and writing device registers.

Use the 8x16 font as a fake Dreamcast ROM font. Adding fake/skeleton Dreamcast ROM SYSINFO_INIT, SYSINFO_ID, FLASHROM_INIT, and FLASHROM_RAED calls.

Make NetBSD/dreamcast etc. boot correctly with 480 pixels in the y direction (random read hack from PDTRA).

In SH4 instruction trace, include address in printout in a few more cases than before.

When unimplemented SuperH instructions cause an abort failure, GXemul now drops into the debugger instead of calling exit() (if started with -K).
