And also specify the maximum size when writing to static buffers. The
warning below refers to the case where "str5" could be larger than
"str5 - str4", then the strcat would have overlapping dst and src.
Compiler doesn't pick up the bound from the snprintf above, so we make
clear the bounds of str5 by using strncat() instead of strcat().

More tests could probably be added, but this should cover
concatenation, resizing, clearing, formatted printing,
and checking the length, so it should be quite complete.

V2: Address review feedback from Timothy, plus fixes
- Use a large enough char array
- Actually test the formatted appending
- Test that clear function resets string length
V3: Port to gtest
V4: Fix test makefile
Fix copyright header
Fix missing extern C
Use more appropriate name for C-file
Add tests for append_char
