The timestamp argument to a trace event method is documented as follows:
The method can also take a timestamp argument before the trace event
arguments:
def runstate_set(self, timestamp, new_state):
...
Timestamps have the uint64_t type and are in nanoseconds.
In reality methods with a timestamp argument actually receive a tuple
like (123456789,) as the timestamp argument. This is due to a bug in
simpletrace.py.
This patch unpacks the tuple so that methods receive the correct
timestamp argument type.

A persistent build problem we see is where a source file
accidentally omits the #include of log.h. This slips through
local developer testing because if you configure with the
default (log) trace backend trace.h will pull in log.h for you.
Compilation fails only if some other backend is selected.
To make this error cause a compile failure regardless of
the configured trace backend, split out the parts of log.h
that trace.h requires into a new log-for-trace.h header.
Since almost all manual uses of the log.h functions will
use constants or functions which aren't in log-for-trace.h,
this will let us catch missing #include "qemu/log.h" more
consistently.

[eblake: rebase to master]
Signed-off-by: Eric Blake <eblake@redhat.com>
Our qapi-schema.json is composed of modules connected by include
directives, but the generated code is monolithic all the same: one
qapi-types.h with all the types, one qapi-visit.h with all the
visitors, and so forth. These monolithic headers get included all
over the place. In my "build everything" tree, adding a QAPI type
recompiles about 4800 out of 5100 objects.
We wouldn't write such monolithic headers by hand. It stands to
reason that we shouldn't generate them, either.
Split up generated qapi-types.h to mirror the schema's modular
structure: one header per module. Name the main module's header
qapi-types.h, and sub-module D/B.json's header D/qapi-types-B.h.
Mirror the schema's includes in the headers, so that qapi-types.h gets
you everything exactly as before. If you need less, you can include
one or more of the sub-module headers. To be exploited shortly.
Split up qapi-types.c, qapi-visit.h, qapi-visit.c, qmp-commands.h,
qmp-commands.c, qapi-event.h, qapi-event.c the same way.
qmp-introspect.h, qmp-introspect.c and qapi.texi remain monolithic.
The split of qmp-commands.c duplicates static helper function
qmp_marshal_output_str() in qapi-commands-char.c and
qapi-commands-misc.c. This happens when commands returning the same
type occur in multiple modules. Not worth avoiding.
Since I'm going to rename qapi-event.[ch] to qapi-events.[ch], and
qmp-commands.[ch] to qapi-commands.[ch], name the shards that way
already, to reduce churn. This requires temporary hacks in
commands.py and events.py. Similarly, c_name() must temporarily
be taught to munge '/' in common.py. They'll go away with the rename.

Linking code from multiple separate QAPI schemata into the same
program is possible, but involves some weirdness around built-in
types:
* We generate code for built-in types into .c only with option
--builtins. The user is responsible for generating code for exactly
one QAPI schema per program with --builtins.
* We generate code for built-in types into .h regardless of
--builtins, but guarded by #ifndef QAPI_VISIT_BUILTIN. Because all
copies of this code are exactly the same, including any combination
of these headers works.
Replace this contraption by something more conventional: generate code
for built-in types into their very own files: qapi-builtin-types.c,
qapi-builtin-visit.c, qapi-builtin-types.h, qapi-builtin-visit.h, but
only with --builtins. Obey --output-dir, but ignore --prefix for
them.
Make qapi-types.h include qapi-builtin-types.h. With multiple
schemata you now have multiple qapi-types.[ch], but only one
qapi-builtin-types.[ch]. Same for qapi-visit.[ch] and
qapi-builtin-visit.[ch].
Bonus: if all you need is built-in stuff, you can include a much
smaller header. To be exploited shortly.

The include directive permits modular QAPI schemata, but the generated
code is monolithic all the same. To permit generating modular code,
the front end needs to pass more information on inclusions to the back
ends. The commit before last added the necessary information to the
parse tree. This commit adds it to the intermediate representation
and its QAPISchemaVisitor. A later commit will use this to to
generate modular code.
New entity QAPISchemaInclude represents inclusions. Call new visitor
method visit_include() for it, so visitors can see the sub-modules a
module includes.
Note that unlike other entities, QAPISchemaInclude has no name, and is
therefore not added to entity_dict.
New QAPISchemaEntity attribute @module names the entity's source file.
Call new visitor method visit_module() when it changes during a visit,
so visitors can keep track of the module being visited.

The parse tree is a list of expressions. Except include expressions
currently get replaced by the included file's parse tree.
Instead of throwing away the include expression, keep it with the file
name expanded so you don't have to track the including file's
directory to make sense of it.
A future commit will put this include expression to use.

A massive number of objects depends on QAPI-generated headers. In my
"build everything" tree, it's roughly 4800 out of 5100. This is
particularly annoying when only some of the generated files change,
say for a doc fix.
Improve qapi-gen.py to touch its output files only if they actually
change. Rebuild time for a QAPI doc fix drops from many minutes to a
few seconds. Rebuilds get faster for certain code changes, too. For
instance, adding a simple QMP event now recompiles less than 200
instead of 4800 objects. But adding a QAPI type is as bad as ever;
we've clearly got more work to do.

Whenever qapi-schema.json changes, we run six programs eleven times to
update eleven files. Similar for qga/qapi-schema.json. This is
silly. Replace the six programs by a single program that spits out
all eleven files.
The programs become modules in new Python package qapi, along with the
helper library. This requires moving them to scripts/qapi/. While
moving them, consistently drop executable mode bits.

These classes encapsulate accumulating and writing output.
Convert C code generation to QAPIGenC and QAPIGenH. The conversion is
rather shallow: most of the output accumulation is not converted.
Left for later.
The indentation machinery uses a single global variable indent_level,
even though we generally interleave creation of a .c and its .h. It
should become instance variable of QAPIGenC. Also left for later.
Documentation generation isn't converted, and QAPIGenDoc isn't used.
This will change shortly.

Each generator carries a copyright notice for the generator itself,
and another one for the files it generates. Only the former have been
updated along the way, the latter have not, and are all out of date.
Fix by copying the generator's copyright notice to the generated files
instead. Note that the fix doesn't copy the "Authors:" part; the
generated files' outdated Authors list goes away without replacement.
