QemuOpts: add qemu_opt_get_*_del functions for replace work
Add qemu_opt_get_del, qemu_opt_get_bool_del, qemu_opt_get_number_del and qemu_opt_get_size_del to replace the same handling of QEMUOptionParameter (get and delete). Several drivers are coded to parse a known subset of options, then remove them from the list before handing all remaining options to a second driver for further option processing. get_*_del makes it easier to retrieve a known option (or its default) and remove it from the list all in one action. Share common helper function: For qemu_opt_get_bool/size/number, they and their get_*_del counterpart could share most of the code except whether or not deleting the opt from option list, so generate common helper functions. For qemu_opt_get and qemu_opt_get_del, keep code duplication, since 1. qemu_opt_get_del returns malloc'd memory while qemu_opt_get returns in-place memory 2. qemu_opt_get_del returns (char *), qemu_opt_get returns (const char *), and could not change to (char *), since in one case, it will return desc->def_value_str, which is (const char *).
