2017-12-17Declare non-local variables as const where possibleAaron Puchert
Having non-const variables of static lifetime or even global scope is usually a bad idea. These variables are inherently constants, and this should be enforced. This required marking some functions as not modifying input parameters and marking some pointers as pointers to const. One advantage is that the compiler usually puts const static variables in a read-only code segment, so they can't be modified physically. This can be verified with `nm` (on POSIX systems). To avoid changes to the public API, functions returning non-const pointers to data tables were left intact, but the returned data may not be modified. Internally we prefer using the proj_list_* functions over the pj_get_*_ref functions, because the former return const pointers.
2017-10-19Prevent crashes and leaks on allocation failure (#606)Aaron Puchert
* Prevent crashes and leaks on allocation failure Memory allocation can fail. We need to gracefully handle this case and prevent dereferencing null pointers. * Make NULL checks consistent within a file * Properly report allocation errors * Improve cleanup in pj_gc_reader.c * Implement pj_strdup and use instead of strdup The function strdup is not part of ANSI C 89, but a POSIX extension. Therefore we can not rely on it being available on all platforms.

Some of these should be false positives, but I re-wrote them anyway because they were unclear.
