Earle F. Philhower, III 03ea61a32a Add valgrind and string tests to host_tests (#4939)
* Add valgrind and string tests to host_tests

Valgrind identified an error that was causing intermittent failures in
the host tests, and can check for subtle memory access and allocation bugs.
Add it to the standard host_test suite, and any errors will cause test
failure.

Also start adding string tests, since two undefined behaviors have been
found so far just by inspection.

* Add additional String tests

Looks like a possible bug in the concatenation operator, need to verify
expected behavior.

* Remove verbose from valgrind run

No need to be so chatty on the test.  Errors were a little hard to spot.
Go to normal verbosity.

* Add lcov and more string tests

LCOV and genhtml can generate nice HTML coverage charts hilighting test
coverage issues in a much simpler way than gcov text format.  Generate these
automatically from gcov output.

Add additional string creation and comparison tests.

* Move String coverage to >50%

Additional string tests and checks

* 66% test coverage in String

* Add allocation-unit-sized strings test

Ensure that strings that are right on the edge of the allocation
size are handled properly and account for trailing 0.
