Markus Armbruster 77daece3d9 qapi: Inline check_name() into check_union()
check_name() consists of check_name_is_str() and check_name_str().
check_union() relies on the latter to catch optional discriminators.
The next commit will replace that by a more straightforward check.
Inlining check_name() into check_union() now should make that easier
to review.

Markus Armbruster 88112488cf qapi: Make check_type()'s array case a bit more obvious
check_type() checks the array's contents, then peels off the array and
falls through to the "not array" code without resetting allow_array
and allow_dict to False.  Works because the peeled value is a string,
and allow_array and allow_dict aren't used then.  Tidy up anyway:
recurse instead, defaulting allow_array and allow_dict to False.

Markus Armbruster 67fa64ce0e qapi: Move check for reserved names out of add_name()
The checks for reserved names are spread far and wide.  Move one from
add_name() to new check_defn_name_str().  This is a first step towards
collecting them all in dedicated name checking functions next to
check_name().

While there, drop the quotes around the meta-type in
check_name_str()'s error messages: "'command' uses ... name 'NAME'"
becomes "command uses ... name 'NAME'".

Markus Armbruster d7bc17c602 qapi: Improve reporting of invalid name errors
Split check_name() into check_name_is_str() and check_name_str(), keep
check_name() as a wrapper.

Move add_name()'s call into its caller check_exprs(), and inline.

This permits delaying check_name_str() there, so its error message
gains an "in definition" line.

Markus Armbruster 2ab218aad6 qapi: Change frontend error messages to start with lower case
Starting error messages with a capital letter complicates things when
text can get interpolated both at the beginning and in the middle of
an error message.  The next patch will do that.  Switch to lower case
to keep it simpler.

For what it's worth, the GNU Coding Standards advise the message
"should not begin with a capital letter when it follows a program name
and/or file name, because that isn’t the beginning of a sentence. (The
sentence conceptually starts at the beginning of the line.)"

While there, avoid breaking lines containing multiple arguments in the
middle of an argument.

Markus Armbruster 638c4af931 qapi: Clean up member name case checking
QAPISchemaMember.check_clash() checks for member names that map to the
same c_name().  Takes care of rejecting duplicate names.

It also checks a naming rule: no uppercase in member names.  That's a
rather odd place to do it.  Enforcing naming rules is
check_name_str()'s job.

qapi-code-gen.txt specifies the name case rule applies to the name as
it appears in the schema.  check_clash() checks c_name(name) instead.
No difference, as c_name() leaves alone case, but unclean.

Move the name case check into check_name_str(), less the c_name().
New argument @permit_upper suppresses it.  Pass permit_upper=True for
definitions (which are not members), and when the member's owner is
whitelisted with pragma name-case-whitelist.

Bonus: name-case-whitelist now applies to a union's inline base, too.
Update qapi/qapi-schema.json pragma to whitelist union CpuInfo instead
of CpuInfo's implicit base type's name q_obj_CpuInfo-base.

Markus Armbruster 7be6c51194 qapi: Prefix frontend errors with an "in definition" line
We take pains to include the offending expression in error messages,
e.g.

    tests/qapi-schema/alternate-any.json:2: alternate 'Alt' member 'one' cannot use type 'any'

But not always:

    tests/qapi-schema/enum-if-invalid.json:2: 'if' condition must be a string or a list of strings

Instead of improving them one by one, report the offending expression
whenever it is known, like this:

    tests/qapi-schema/enum-if-invalid.json: In enum 'TestIfEnum':
    tests/qapi-schema/enum-if-invalid.json:2: 'if' condition must be a string or a list of strings

Error messages that mention the offending expression become a bit
redundant, e.g.

    tests/qapi-schema/alternate-any.json: In alternate 'Alt':
    tests/qapi-schema/alternate-any.json:2: alternate 'Alt' member 'one' cannot use type 'any'

I'll take care of that later in this series.

Markus Armbruster 0ca7b11709 qapi: Tighten QAPISchemaFOO.check() assertions
When we introduced the QAPISchema intermediate representation (commit
ac88219a6c), we took a shortcut: we left check_exprs() & friends
alone instead of moving semantic checks into the
QAPISchemaFOO.check().  check_exprs() still checks and reports errors,
and the .check() assert check_exprs() did the job.  There are a few
gaps, though.

QAPISchemaArrayType.check() neglects to assert the element type is not
an array.  Add the assertion.

QAPISchemaObjectTypeVariants.check() neglects to assert the tag member
is not optional.  Add the assertion.

It neglects to assert the tag member is not conditional.  Add the
assertion.

It neglects to assert we actually have variants.  Add the assertion.

It asserts the variants are object types, but neglects to assert they
don't have variants.  Tighten the assertion.

QAPISchemaObjectTypeVariants.check_clash() has the same issue.
However, it can run only after .check().  Delete the assertion instead
of tightening it.

QAPISchemaAlternateType.check() neglects to assert the branch types
don't conflict.  Fixing that isn't trivial, so add just a TODO comment
for now.  It'll be resolved later in this series.

Michal Privoznik 2546be1c85 qmp-dispatch: Use CommandNotFound error for disabled commands
If a command is disabled an error is reported.  But due to usage of
error_setg() the class of the error is GenericError which does not
help callers in distinguishing this case from a case where a qmp
command fails regularly due to other reasons.

We used to use class CommandDisabled until the great error
simplification (commit de253f1491 for QMP and commit 93b91c59db for
qemu-ga, both v1.2.0).

Use CommandNotFound error class, which is close enough.

As part of the push to drop python2 support, replace any explicit python2
dependencies with python3 versions.

For centos, python2 still exists as an implicit dependency, but by adding
python3 we will be able to build even if the configure script begins to
require python 3.5+.

Tested with centos7, fedora, ubuntu, ubuntu1804, and debian 9 (amd64).
Tested under a custom configure script that requires Python 3.5+.

the travis dockerfile is also moved to using python3, which was tested
by running `make docker-test-build@travis`, which I hope is sufficient.

Alex Bennée daa79d9a65 configure: preserve PKG_CONFIG for subdir builds
The slirp sub-module complains about not being able to find the glib
library on cross-compiles because it is using the default pkg-config
tool (which isn't installed in our cross-build docker images).
Preserve PKG_CONFIG in our host config and pass it down to slirp.

Alex Bennée b9fe0063b7 tests/tcg: add simple record/replay smoke test for aarch64
This adds two new tests that re-use the memory test to check basic
record replay functionality is still working. We have to define our
own runners rather than using the default pattern as we want to change
the test name but re-use the memory binary.

We declare the test binaries as PHONY as they don't really exist.

[AJB: A better test would output some sort of timer value or other
otherwise variable value so we could compare the record and replay
outputs and ensure they match]

This is a generic floating point multiply and accumulate test for
