[PATCH v7 0/4] gdbstub and TCG plugin improvements

[Akihiko Odaki]

This series extracts fixes and refactorings that can be applied
independently from "[PATCH v9 00/23] plugins: Allow to read registers".

The patch "target/riscv: Move MISA limits to class" was replaced with
patch "target/riscv: Move misa_mxl_max to class" since I found instances
may have different misa_ext_mask.

V6 -> V7:
  Rebased.

V5 -> V6:
  Added patch "default-configs: Add TARGET_XML_FILES definition".
  Rebased.

V4 -> V5:
  Added patch "hw/riscv: Use misa_mxl instead of misa_mxl_max".

V3 -> V4:
  Added patch "gdbstub: Check if gdb_regs is NULL".

V2 -> V3:
  Restored patch sets from the previous version.
  Rebased to commit 800485762e6564e04e2ab315132d477069562d91.

V1 -> V2:
  Added patch "target/riscv: Do not allow MXL_RV32 for TARGET_RISCV64".
  Added patch "target/riscv: Initialize gdb_core_xml_file only once".
  Dropped patch "target/riscv: Remove misa_mxl validation".
  Dropped patch "target/riscv: Move misa_mxl_max to class".
  Dropped patch "target/riscv: Validate misa_mxl_max only once".
