The commit adds to the generate_code.pl script support to add #line directives
to generated code to allow build breaks to be more easily found from the
generated code.
Added a verbose option to the generated test suites which can list the
dependencies not met for skipped test cases.
Also clarifies internal interfaces between the main_test.function and test code,
and fixed a bug on calculating available tests in run-test-suites.pl.
Restructed test suite helper and main code to support tests suite helper
functions, changed C++ comments to C-style, and made the generated
source code more navigable.
Added to generate_code.pl:
- support for per test suite helper functions
- description of the structure of the files the script uses to construct
the test suite file
- delimiters through the source code to make the machine generated code
easier to understand
Our Windows implementation based on vsnprintf_s( ..., _TRUNCATE ) sometimes
writes *two* terminating NULLs. Allow for that, but obviously bytes past the
end of the buffer mustn't be touched.
- Added in each tests program to be sure they are run (putting them in a test
suite/function specific to the platform layer would cause them to be skipped
when PLATFORM_C is not defined).
- Platforms have already moved from a standard to a broken snprintf in the
past [1], so make sure to catch that if it ever happens again.

Things that are not guaranteed by the standard but should be true of all
platforms of interest to us:
- 8-bit chars
- NULL pointers represented by all-bits-zero
compile time
The new test framework generates a data file parsing engine plus the
templated function code. In order to 'understand' defines, during
the generation phase, a mapping is made to check for dependencies and
result code mappings.
