dynbuf: return NULL when there's no buffer length

2020-05-17T21:20:56+00:00

... as returning a "" is not a good idea as the string is supposed to be
allocated and returning a const string will cause issues.

source cleanup: remove all custom typedef structs

2020-05-15T06:54:42+00:00

 - Stick to a single unified way to use structs
 - Make checksrc complain on 'typedef struct {'
 - Allow them in tests, public headers and examples

 - Let MD4_CTX, MD5_CTX, and SHA256_CTX typedefs remain as they actually
   typedef different types/structs depending on build conditions.

Closes #5338
