[PATCH v1 00/28 for 5.0] testing and gdbstub

[Alex Bennée]

Hi,

This is the last chance to get any reviews in before I send a pull
request later today. To avoid having multiple PRs I've combined both
the testing changes and the gdbstub updates. In the end I had to drop
Gerd's vm updates as it cause problems with the acceptance testing.

The following patches still need review:
 - tests/tcg/aarch64: add test-sve-ioctl guest-debug test
 - tests/tcg/aarch64: add SVE iotcl test
 - tests/tcg/aarch64: add a gdbstub testcase for SVE registers
 - target/arm: generate xml description of our SVE registers
 - target/arm: prepare for multiple dynamic XMLs
 - target/i386: use gdb_get_reg helpers

Alex Bennée (20):
  gdbstub: make GDBState static and have common init function
  gdbstub: stop passing GDBState * around and use global
  gdbstub: move str_buf to GDBState and use GString
  gdbstub: move mem_buf to GDBState and use GByteArray
  gdbstub: add helper for 128 bit registers
  target/arm: use gdb_get_reg helpers
  target/m68k: use gdb_get_reg helpers
  target/i386: use gdb_get_reg helpers
  gdbstub: extend GByteArray to read register helpers
  target/arm: prepare for multiple dynamic XMLs
  target/arm: explicitly encode regnum in our XML
  target/arm: default SVE length to 64 bytes for linux-user
  target/arm: generate xml description of our SVE registers
  target/arm: don't bother with id_aa64pfr0_read for USER_ONLY
  tests/tcg/aarch64: userspace system register test
  configure: allow user to specify what gdb to use
  tests/guest-debug: add a simple test runner
  tests/tcg/aarch64: add a gdbstub testcase for SVE registers
  tests/tcg/aarch64: add SVE iotcl test
  tests/tcg/aarch64: add test-sve-ioctl guest-debug test

Changbin Du (1):

    to gdb

Damien Hedde (2):
  gdbstub: change GDBState.last_packet to GByteArray
