error_is_set(&var) is the same as var != NULL, but it takes
whole-program analysis to figure that out. Unnecessarily hard for
optimizers, static checkers, and human readers. Dumb it down to
obvious.
Gets rid of several dozen Coverity false positives.
Note that the obvious form is already used in many places.

Currently string-output-visitor formats floats as %g, which is nice in
that trailing 0's are automatically truncated, but otherwise this causes
some issues:
- it uses 6 significant figures instead of 6 decimal places, which
means something like 155777.5 (which even has an exact floating point
representation) will be rounded to 155778 when converted to a string.
- output will be presented in scientific notation when the normalized
form requires a 10^x multiplier. Not a huge deal, but arguably less
readable for command-line arguments.
- due to using scientific notation for numbers requiring more than 6
significant figures, instead of hard-defined decimal places, it
fails a lot of the test-visitor-serialization unit tests for floats.
Instead, let's just use %f, which is what the QJSON and the QMP visitors
use.

This introduces new test reporting infrastructure based on
gtester and gtester-report.
Also, all existing tests are moved to tests/, and tests/Makefile
is reorganized to factor out the commonalities in the rules.
