[PATCH v2 0/5] TriCore fixes and gdbstub

[Bastian Koppelmann <kbastian@mail.uni-paderborn.de>]

Hi,

this series fixes a few TriCore problems:

- Segfault due to non initialized ctx->env ptr (see
  https://lists.gnu.org/archive/html/qemu-devel/2019-09/msg03527.html)
  I fixed this by properly detangling any reference of the env pointer in the
  translate functions. (as suggested by Peter Maydell)

- Unimplemented tricore_cpu_get_phys_page_debug() which lead to a temporary fix
  (see b190f477e29c7cd03a8fee49c96d27f160e3f5b0)

The last patch implements a gdbstub for TriCore.

Cheers,
Bastian

v1 -> v2:
  - Fixed codingstyle problems
  - tricore_cpu_gdb_read_registers uses a GByteArray pointer for the mem_buf
    argument
