b4548fcc03 trace: Remove %s in grlib trace events
Trace events cannot use %s in their format strings because trace
backends vary in how they can deference pointers (if at all).  Recording
const char * values is not meaningful if their contents are not recorded
too.

Change grlib trace events that rely on strings so that they communicate
similar information without using strings.

A follow-up patch explains this limitation and updates docs/tracing.txt.

a980a065fb usb: move USB_REQ_{GET,SET}_CONFIGURATION handling to common code
This patch adds fields to the USBDevice struct for the current
speed (hard-wired to full speed for now) and current device
configuration.  Also a init function is added which inializes
these fields.  This allows USB_REQ_{GET,SET}_CONFIGURATION
handling to be moved to common code.

For most drivers the conversion is trivial ad they support a single
configuration only anyway.  One exception is bluetooth where some
device-specific setup code runs after get/set configuration.  The
other is usb-net which actually has two configurations so the
the code to check for the active configuration has been adapted.

37fb59d303 usb: data structs and helpers for usb descriptors.
This patch adds hw/usb-desc.[ch] files.  They carry data structures
for various usb descriptors and helper functions to generate usb
packets from the structures.

The intention is to have a internal representation of the device
desription which is more usable than the current char array blobs,
so we can have common code handle common usb device emulation using
the device description.

The usage of this infrastructure is optional for usb drivers as there
are cases such as pass-through where it probably isn't very useful.

This patch adds code to look up data cluster offsets in the image via
the L1/L2 tables.  The L2 tables are writethrough cached in memory for
performance (each read/write requires a lookup so it is essential to

bdrv_is_allocated() to query the number of contiguous
allocated/unallocated clusters.

from trace-events is not enough since source code will call the
trace_*() function for the event.

This patch makes it easy to build without specific trace events by

trace: Allow bulk enabling/disabling of trace events at compile time

For 'simple' trace backend, allow bulk enabling/disabling of trace
events at compile time.  Trace events that are preceded by 'disable'
keyword are compiled in, but turned off by default. These can
individually be turned on using the monitor.  All other trace events are
enabled by default.

This could be enhanced when the trace-event namespace is partitioned into a
group and an ID within that group. In such a case, marking a group as enabled
would automatically enable all trace-events listed under it.

94a420b170 trace: Add trace-events file for declaring trace events
This patch introduces the trace-events file where trace events can be
declared like so:

qemu_malloc(size_t size) "size %zu"
qemu_free(void *ptr) "ptr %p"

These trace event declarations are processed by a new tool called
tracetool to generate code for the trace events.  Trace event
declarations are independent of the backend tracing system (LTTng User
Space Tracing, ftrace markers, DTrace).

The default "nop" backend generates empty trace event functions.
Therefore trace events are disabled by default.

The trace-events file serves two purposes:

1. Adding trace events is easy.  It is not necessary to understand the
   details of a backend tracing system.  The trace-events file is a
   single location where trace events can be declared without code
   duplication.

2. QEMU is not tightly coupled to one particular backend tracing system.
   In order to support tracing across QEMU host platforms and to
   anticipate new backend tracing systems that are currently maturing,
   it is important to be flexible and not tied to one system.
