John Snow 7a6a740d8d qtest: Add base64 encoded read/write
For larger pieces of data that won't need to be debugged and
viewing the hex nibbles is unlikely to be useful, we can encode
data using base64 instead of encoding each byte as %02x, which
leads to some space savings and faster reads/writes.

For now, the default is left as hex nibbles in memwrite() and memread().
For the purposes of making qtest io easier to read and debug, some
callers may want to specify using the old encoding format for small
patches of data where the savings from base64 wouldn't be that profound.

memwrite/memread use a data encoding that takes 2x the size of the original
buffer, but base64 uses "only" (4/3)x, so for larger buffers we can save a
decent amount of time and space.

John Snow ba4ed39346 libqtest: add qmp_async
Add qmp_async, which lets us send QMP commands asynchronously.
This is useful when we want to send commands that will trigger
event responses, but we don't know in what order to expect them.

Sometimes the event responses may arrive even before the command
confirmation will show up, so it is convenient to leave the responses
in the stream.

Stefan Hajnoczi 89b516d8b9 glib: add compatibility interface for g_get_monotonic_time()
This patch fixes compilation errors when building against glib <2.28.0
due to the missing g_get_monotonic_time() function.

The compilation error in tests/libqos/virtio.c was introduced in commit
70556264a8 ("libqos: use microseconds
instead of iterations for virtio timeout").

Add a simple g_get_monotonic_time() implementation to glib-compat.h
based on code from vhost-user-test.c.

Stefan Hajnoczi 96b8ca47f8 Revert "qtest: Fix crash if SIGABRT during qtest_init()"
It turns out there are test cases that use multiple libqtest instances.
We cannot use a global qtest instance in the SIGABRT handler.

This reverts commit cb201b4872.

Stefan Hajnoczi cb201b4872 qtest: Fix crash if SIGABRT during qtest_init()
If an assertion fails during qtest_init() the SIGABRT handler is
invoked.  This is the correct behavior since we need to kill the QEMU
process to avoid leaking it when the test dies.

The global_qtest pointer used by the SIGABRT handler is currently only
assigned after qtest_init() returns.  This results in a segfault if an
assertion failure occurs during qtest_init().

Move global_qtest assignment inside qtest_init().  Not pretty but let's
face it - the signal handler depends on global state.

Peter Maydell 0100f42550 libqtest: Avoid inline varargs functions
Older versions of gcc (eg 4.6) can't handle varargs functions declared
inline for anything other than completely trivial uses, and complain:

tests/qom-test.c: In function 'qmp': tests/libqtest.h:359:60: sorry,
unimplemented: function 'qmp' can never be inlined because it uses
variable argument lists

Avoid this problem by putting the functions into libqtest.c instead
of using inline definitions in libqtest.h.

Andreas Färber 6acf801de5 libqtest: Convert macros to functions and clean up documentation
libqtest.h provides a number of shortcut macros to avoid tests feeding
it the QTestState they operate on. Most of these can easily be turned
into static inline functions, so let's do that for clarity.
This avoids getting off-by-one error messages when passing wrong args.

Some macros had a val argument but documented @value argument. Fix this.

While touching things, enforce gtk-doc markup for return values and for
referencing types.
