Commits 7216ae3d and d2828429 disabled some error message hints, all because a change to use modern error reporting meant that the hint would be output prior to the actual error. Fix this by making hints a first-class member of Error. For example, we are now back to the pleasant: $ qemu-system-x86_64 --nodefaults -S --vnc :0 --chardev null,id=, qemu-system-x86_64: --chardev null,id=,: Parameter 'id' expects an identifier Identifiers consist of letters, digits, '-', '.', '_', starting with a letter.

The -msg timestamp=on option prepends a timestamp to error messages. This is useful on stderr where it allows users to identify when an error was raised. Timestamps do not make sense on the monitor since error_report() is called in response to a synchronous monitor command and the user already knows "when" the command was issued. Additionally, the rest of the monitor conversation lacks timestamps so the error timestamp cannot be correlated with other activity. Only prepend timestamps on stderr. This fixes libvirt's 'drive_del' processing, which did not expect a timestamp. Other QEMU monitor clients are probably equally confused by timestamps on monitor error messages.

The SOFT_RST or RXEN in the control register can be used as a condition to unblock the net layer via can_receive(). So check for possible flushes on RCR changes.

Return false from can_receive() when the FIFO doesn't have a free RX slot. This fixes a bug in the current code where the allocated buffer is freed before the fifo pop, triggering a premature flush of queued RX packets. It also will handle a corner case, where the guest manually frees the allocated buffer before popping the rx FIFO (hence it is not enough to just delay the flush_queued_packets()).

The goal is to split the functions such that cpu-exec is CPU specific content, while cpus-exec-common.c is generic code only. The function interface to cpu-exec needs to be virtualised to prepare support for multi-arch and moving these definitions out saves bloating the QOM interface. So move these definitions out of cpu-exec to a new module, cpu-exec-common.

Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T).

cp_virtio is called for both the asm-s390/ and linux/ directories, so it looks for pci_regs.h and input.h files in asm-s390/ too. This makes little sense.

We do not want to copy linux/hyperv.h. The solution is to make cp_virtio (now renamed to cp_portable) copy one file only, instead of using the "find" command, and call it multiple times.
