The good news is that there is a tsort in the python standard library; the bad news is that it was only added in Python 3.9. To bridge the gap between our current minimum supported Python version and 3.9, provide a local implementation that has the same API as the stdlib version for the parts we care about. In future when QEMU's minimum Python version requirement reaches 3.9 we can delete this code and replace it with an 'import' line.

<zhiwei_liu@linux.alibaba.com> For riscv host, it will set dec->cfg to zero. Thus we shuld guard the dec->cfg deference for riscv host disassemble. And in general, we should only use dec->cfg for target in three cases: 1) For not incompatible encodings, such as zcmp/zcmt/zfinx. 2) For maybe-ops encodings, they are better to be disassembled to the "real" extensions, such as zicfiss. The guard of dec->zimop and dec->zcmop is for comment and avoid check for every extension that encoded in maybe-ops area. 3) For custom encodings, we have to use dec->cfg to disassemble custom encodings using the same encoding area.

Therefore, when they generate exceptions, they are not handled by cpu_restore_state_from_tb(). For x86 this is not a problem, because x86_restore_state_to_opc() only restores pc and cc, which already have the correct values if the first TB instruction causes an exception. However, on several other architectures, restore_state_to_opc() is not stricly limited to state restoration and affects some exception-related registers, where guests can notice incorrect values, for example: - arm's exception.syndrome; - hppa's unwind_breg; - riscv's excp_uw2; - s390x's int_pgm_ilen. Fix by always calling tcg_tb_insert(). This may increase the size of region_trees, but tcg_region_reset_all() clears it once code_gen_buffer fills up, so it will not grow uncontrollably. Do not call tb_link_page(), which would add such TBs to the QHT, to prevent tb_lookup() from finding them. These TBs are single-use, since subsequent reads from I/O memory may return different values; they are not removed from code_gen_buffer only in order to keep things simple.
