Replace assert(0) with abort() or cpu_abort()

When building with -DNDEBUG, assert(0) will not stop execution
so it must not be used for abnormal termination.

Use cpu_abort() when in CPU context, abort() otherwise.

Large page TLB flush

QEMU uses a fixed page size for the CPU TLB. If the guest uses large
pages then we effectively split these into multiple smaller pages, and
populate the corresponding TLB entries on demand.

When the guest invalidates the TLB by virtual address we must invalidate...

Remove cpu_get_phys_page_debug from userspace emulation

cpu_get_phys_page_debug makes no sense for userspace emulation, so remove it.

CRIS: Segmented addressing only for kernel mode.

Segmented translation through the CRIS MMU is only done for
accesses in kernel mode. In user-mode, all accesses are treated
as paged regardless of the mode config in RW_MM_CFG.

Revert "Get rid of _t suffix"

In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem. Something
like this must be presented on the list first so people can provide input...

Get rid of _t suffix

Clean up debugging code #ifdefs (Eduardo Habkost)

Use macros to avoid #ifdefs on debugging code.

This patch doesn't try to merge logging macros from different files,
but just unify the debugging code #ifdefs onto a macro on each file. A
further cleanup can unify the debugging macros on a common header, later...
