[Qemu-devel] [PULL 2/8] tests/libqos/e1000e: Make e1000e libqos functions independent from global_qtest

[Thomas Huth <thuth@redhat.com>]

libqos library functions should never depend on functions (like memread(),
memwrite() or clock_step()) that require global_qtest to be set, since
library functions might get used in qtests that track multiple states, too.
Thus let's replace the global_qtest-related functions with their independent
counterparts.
