[Qemu-devel] [PATCH v7] util/path: Use the GLib memory allocation routines

[zhanghailiang <zhang.zhanghailiang@huawei.com>]

In this file, we don't check the return value of malloc/strdup/realloc which may fail.
Instead of using these routines, we use the GLib memory APIs g_malloc/g_strdup/g_realloc.
They will exit on allocation failure, so there is no need to test for failure,
which would be fine for setup.
