88a0ef00d7 enforce use of G_GNUC_PRINTF attributes
We've been very gradually adding G_GNUC_PRINTF annotations
to functions over years. This has been useful in detecting
certain malformed printf strings, or cases where we pass
user data as the printf format which is a potential security
flaw.

Given the inherant memory corruption danger in use of format
strings vs mis-matched variadic arguments, it is worth applying
G_GNUC_PRINTF to all functions using printf, even if we know
they are safe.

The compilers can reasonably reliably identify such places
with the -Wsuggest-attribute=format / -Wmissing-format-attribute
flags.

e0a2602070 tests/fp: Do not build softfloat3 tests if TCG is disabled
Technically we don't need the TCG accelerator to run the
softfloat3 tests. However it is unlikely an interesting
build combination. Developers using softfloat3 likely use
TCG too. Similarly, developers disabling TCG shouldn't
mind much about softfloat3 tests.

This reduces a non-TCG build by 474 objects!

004900acbc tests/fp/berkeley-testfloat-3: Ignore ignored #pragma directives
Since we already use -Wno-unknown-pragmas, we can also use
-Wno-ignored-pragmas. This silences hundred of warnings using
clang 13 on macOS Monterey:

3d2f73ef75 build: use "meson test" as the test harness
"meson test" starting with version 0.57 is just as capable and easy to
use as QEMU's own TAP driver.  All existing options for "make check"
work.  The only required code change involves how to mark "slow" tests;
they need to belong to an additional "slow" suite.

The rules for .tap output are replaced by JUnit XML; GitLab is able
to parse that output and present it in the CI pipeline report.

2fa3546c8f softfloat: Move floatN_log2 to softfloat-parts.c.inc
Rename to parts$N_log2.  Though this is partly a ruse, since I do not
believe the code will succeed for float128 without work.  Which is ok
for now, because we do not need this for more than float32 and float64.

Since berkeley-testfloat-3 doesn't support log2, compare float64_log2
vs the system log2.  Fix the errors for inputs near 1.0:
